I applaud you for fighting and wish you luck with your car. But, if your case had to go to court, it would have more than likely gone Mazda's way if the mods involved raised the boost levels beyond what the car came with. And that wouldn't be hard for Mazda to prove.

Supposedly stock cars have blown but given the amount of these cars produced around the world, had this been a regular occurrence, there would more than likely have been a class suit against Mazda regarding the engine. So far I haven't heard anything (not that there isn't one in the making).

You're luckier than you think. Unless you can produce ample evidence that the motor has a defect, it's an open and shut case for Mazda (imo).

Still waiting for my car...

To be honest, I am just getting worn down. Unfortunately, the times I think about the car most often is when I am sitting in front of a computer. This thread just so happened to be close by for my outburst.

I am lucky to have gotten my car fixed and I will most likely pay for the aftermarket part removal and installation. The furthest I will go will be to ask for a reduction which I did today. I was told by the dealership staff that they will reduce the labor time they charge for which is great.

I miss hitting boost :P

blew at 80,000
 

first off i abused my car every day im lucky it lasted this long mazda warranteed about $14,000 in parts through extended and factory warranty. fuel pumps axles differntials and basically anything you can name but they did not warranty my new motor so i wnet all out on the new setup. i had 80,000 miles traveling 135 mph shifted from 5th gear heard pop and then a cylinder misfire occured in cylinder 3 thats all she wrote.shot a hole in the cylinder the technician said the pump leaned out or when i ran syntheic oil the car ate it up so for a recomendation synthetic should not be ran in any disi motor we blow it out i have seen another motor lock up and he used syntheic oil every time he came in at regular intervals and had no oil left in the motor. the current setup was hks twin igniton controller, stock plugs, cobb stage 2 map,cp-e downpipe, corksport tbe, injen cold air intake, apexi super grounding system, stock fuel pump, stock top mount, a ton of suspension work, bsd, oil pan baffle, dynoed the car at 280 whp 312 wtq before it blew up. for current set up check out the profile. bigger and better things are coming in the future.

I find it hard to believe that its the fault of synthetic oil. Synthetic oil is superior to dino oil especially when it comes to its ability to withstand heat. I would say running synthetic oil after break in would actually help with wear/tear on these motors especially.

Furthermore there are other direct injenction motors out there running synthetic oil with no issues.

This makes you one of the first reported people to blow with the BSD.

Did you have water or meth injection by any chance?

so you had an hks twin power and an apexi super grounding?
you had a cpe dp but a corksport tbe?

stock fp also which isnt good

no i was not running methanol i blew the motor so now im building it and changing up the whole setup i got rid of the cobb crap and learned that cp-e is easier to tune with i blew my motor because cobb doesnt say you need a fuel pump to run any of the tunes so when i leaned out nothing could help i had no problems at all the whole time i had the bsd on for three weeks and after that last part the motor went im not sayomg it was the bsd but cobb sucks.

So were you showing dropping fuel pressure under boost?

lol another right after the BSD was done

no i wasnt at all i had no problems before with fuel pressure dropping and right when i shifted into 6th and got back on the throttle the popping occured and then misfire came up and i drove home on two cylinders. the only thing i can think of is the fuel pressure did drop and leaned out and then detonation happened and blew a hole in cyliinder three but the top of the piston melted to the cylinder wall which is like the spark plug got to hot and melted because the spark plug in cylinder one shot off which was suprising since the hole was in three i had fulll compression in the fourth cylinder and the rest were 120 for cylinder 1 and cylinder 2 and three both had around 40 psi if that helps any

ZOOM ZOOM BOOM FTL!!!!!!!!!!!!!
 

another blown motor for this week i tried everything to prevent this from happening (BSD,METH,TUNING)just to name a few!!!!!!!!!!!!!!

^^ how many miles? how did it happen?

It had aroung 14k miles 1st gear around 4k rpm kaboom!!!!!!!!!!!

Can you elaborate on your mods/tune/etc.?

So, I picked up my car yesterday from the dealership.

A couple small things I will have to go back to the dealership about (broken battery box cover, cracked tweeter grill, let them know they did not tighten down my starter 12v+ wire on the battery, random yellow wire running directly over turbo where it will melt, etc.) but other than that, it feels good to have it back.

As for the 4 hours labor, I spoke to the service manager and explained my thoughts. He said he would charge me the internal labor cost which is $85/hour rather than the regular $110/hour. I said great, sounds fair.

When I went to pay, the girls at the service desk said "We didn't hear him say $85/hour so we'll charge you $68/hour". They did hear what the manager said, but it pays off to be sexy ;). Kidding aside, I thought that was pretty fair.

Can a mod please update the list on the 1st page?

Yeah I'm on my second engine. Mazda replaced engine AND turbo under warranty.

New engine knocks every other day between 3-9 degrees. Car is 100% stock now.

I had 60k kms on the engine. Cylinder #4 ceased and did a window in the front of the block taking the starter with it, was in part throttle 3rd gear. Final bill 12,500$.

Thanks Mazda for paying the bill, not sure if they would pay again on my next visit....I guess after 40k more km they couldnt care less.

I read this post from time to time, I have some suggestions for everyone.

STOP CRAPPING UP THIS THREAD. What was a resource thread is now 11 pages of BS.

Would a moderator please delete all non "I blew my engine posts" (to include my post here)
Also I would suggest locking the thread, and a moderator take PM's of new blown engines, then post the FULL info up.

One more thing, anyone that says "well stock cars blow to" is a f-tard. If you personally have one then I feel for you. Otherwise stfu.

The irony of your post...:haha:

Heart Felt Sympathy I'm Sure???
 

If you read the second post, listing the blown motors, you’ll see that there are at least four (including mine) with stock motors and a few more where the only mod is the MS CAI. That Mazda endorsed mod is pretty darn close to stock.

There is a lot of good resource info here, you just have to be able to read it. So what is your point?

When this happenned, did you see any smoke come out the exhaust? Blue/grey smoke possibly?

The car had no smoking issues before it blew up. The car now has smoking issues due to the stock turbo seals haha. If it's not one thing, it's another. Off to Mazda tomorrow for a new turbo hopefully.

I know a guy who blow his engine.. he was in 6th gear shift to 4th, doing about 55mph full throttle, reached 75mph, boom! Was a hole in the engine block, and cracks arond #1 cylinder house... The only mods he had was catbacksystem..
Year of the car was -06 and has gone about 5000miles, Iam from sweden.. dont know what that is in yours miles... think it is like 3000... not much anyway.. And Mazda fixed it on the warrenty.... think he got a new engine..

Has octane rating of fuel used been taken into account in these cases? Sorry if it has been talked about, don't feel like reading all the pages.

+1. Here's a list of the latest I could find that are not on the first page. These are all from this forum, 6 more...

Realgib3
Darksun280
boosted3
Smoke_31
MS3BOOSTIN
Speed I

Can we really count the oil starvation cases?

add me to the list
 

Car; 2007 Mazdaspeed 3 23000ish miles
Cylinder; probably 2
Damage; blew a hole through the block
RPM;5100~
Mods; TurboXs FMIC, Cobb SRI/TIP, Greddy Type-S, AEM UEGO and TRU-BOOST, Street Unit TP, Stock cat-back with removed resonators, PT-Performance Trans Mount
Exhaust Manifold; Stock
Situation; Pulling out to catch up with traffic in 2nd, got on it and the car took off as usual and then boom, smoke and quiet motor. So I just coasted to the nearest side street and pulled off of the main road. My boost controller is set at 16.5 psi.
Warranty; probably not, won't know for a couple of days
Oil; Castrol Edge Synthetic 5w-30

:grumble:

Just to cover the basics: No BSD, No Tune, No Meth correct? Tks

you turned up your boost and your didn't tune for it?

come one now, that is hardly any fault of the manufacturer. with that many mods, you need a custom tune

Who said anything about the manufacturer being at fault?

Anyway, yeah I hadn't gotten around to the BSD yet and the tune was set up to happen on Wed.

question, where you going wot when this happened? and no fp?

imo even if your stock, a dashhawk should be a priority if you buy this car. it is honestly my favorite piece of the car because without it i wouldn't know what is going on with the car.

3000 miles on new motor blew agian
 

engine blew at 10000 miles.....got new engine from mazda.....blew again 13000 miles bone stock......... traded it for a cx-9.....lots parts for sale cp-e standback2, standback2 software, and pnp harness....cobb turbo inlet.....possibly my dashhawk....rks bov...pm me

^^^ Fail?

Anyone see the conflict in that post.

"Blew bone stock."

"Parts for sale: standback2, standback2 software, and pnp harness....cobb turbo inlet.....possibly my dashhawk....rks bov"

I say Standback Tuning FAIL

just brought my car in for service and the manager is pretty cool.

i asked about putting an sri in and if it would be a problem.

he said hell no, just don't put a BOV in. that there were 2 cars in the back with blown engines and that they won't honor the warranty. the big issue was that they couldn't produce any paperwork that they had service done with their car. no receipts, nothing.

i don't know how or why the BOV becomes the deal breaker with the warranty, but i just wanted to share my conversation with you.

thanks

the first blow did happen with the standback, down pipe testpipe, cpe flash on ecu,cobb turbo inlet, aem intake. bent #4 rod at 10000 miles.....they replaced the engine under thier good will policy.....not under warranty.....and under the warning they would not replace it agian.....they did it under good will policy because they found that the # 4 injector definitly stuck causing the # rod to bend.....with the second engine blew with no aftermarket parts including the standback....the ecu was flashed back stock.....I wasnt going to chance that i somehow caused the injector to stick.....didnt matter same #4 rod bent again at 13000...however they already had taken my drivetrain warranty...they recommended trading it in on something else.....i did and took a beating.

Stuck injector hydrolock FTL. Chalk that up as another failure mode.

This thread makes me REALLY nervous about getting a MazdaSpeed 3
How many engines have blown or whatever in these cars?

Just buy one and dont worry, be happy>

did you think i was kidding. Just cause some asshole had the other thread basically locked doesnt mean i was lying. If you want a car in the price range to keep stock get a ms3. IF you want to mod it, dont even get within 100 yds of a mazda dealership

Yet!

Well I haven't decided if I'd mod it (tune) yet or not.
But with a stock psi of 15.5 and hearing that 18 psi is max on the MS3 without doing fuel pump and other work, it hardly seems worth tuning the car to get 2-2.5 psi more out of it (what's 2 psi more boost in the MS3 worth? 20 hp?)

I'm hearing an intake is worth 15-20 though, so that might be something I'd do.

But man there's quite a few blown engines apparently.
The N54 is bullet proof by comparison, it's only issue is the HPFP and even then a small percentage fail, and even then they covered under warranty.
And people are raising the boost twice the stock boost level on the N54 engine, plus race gas, plus meth.

I was kind of hoping the MS3 engine would be even 1/2 that robust.
Guess not. Bummer.

Well if I get one, guess I gotta keep in pretty stock.

if you really want a fwd cheap fun car, srt4 caliber (ugly as sin), cobalt ss/tc (rental car)
You can mod both without worring about leaving rods on the highway while you merge at part throttle. The memebers here are simply in denail. They have gone through so many theories about why this engine blows, ud think they made the car. However they keep blowing, and more excuses keep popping up. REality is, other platforms dont have these problems. The n54 shouldnt even be compared to this motor lol.

A stock MS3 will spike up to 18psi but holds ~14.5psi in 3-6th

A intake MS3 will spike up to 20psi and holds ~16.5psi in 3-6th

The stock airbox is extremely restrictive and 2psi is probably real close to 20hp.

If you get a Cobb AP to go along with an intake I hear the gains are a lot higher because of the tune. Might be looking at close to 30-40whp over stock and make power to redline instead of shy of 6000rpms. Cost would be about 700-900bucks and you would have a 300hp speed3 or pretty close and reliable I think. Even if something happens you have a warranty and the MODS mentioned are very easy to switch back to stock. Not a big deal IMO unless you just got to have major hp which isn't really what this car is about.

The 135/335i bimmers are a lot more expensive than the MS3 so I would hope they'd perform a bit better. When you consider the MS3 is around 24k and it's 2.3L DISI 4cyl motor pumps out 263hp/280ft-lb TQ and the Bimmer is around 36-40k and its 3.0l turbo straight 6cyl pumps out 300hp/300ft-lb TQ it sort of puts things into perspective.

The bimmer has + 2 cyl and +.7L of displacement on the MS3's motor. 300hp with gobs of low/midrange torque isn't too bad for a 2.3L 4cyl motor IMO, its appearantly no EVO/ STI but those have been around a lot longer as well and don't have DISI which is relatively new tech.

Apples and Oranges.

Oh don't get me wrong I wasn't comparing the N54 to this engine.
The N54 is a beaut and basically the 6 cylinder engine of choice to tune.
100 whp gains on that engine is no problem and only about $1500.
Or $600 and race gas.
all this of course you know now.

Again, I'd have another of BMW would of made the 2010 e92 the LCI and given it the DCT of the M3 like they did in Europe for the 335i.


Again, guess if I get an MS3 I'll keep in pretty stock.
Would never get the SRT4
If the Cobalt SS was not so crappy inside, I'd consider.
That 2.0 is stout too and can take ALL KINDS of modding.
Heck there's full on drag race cars with that engine.

I'm considering a VW GTI too.
But the 2.0T is not as smooth as the MS3's 2.3T
And the VW is a bit more expensive for really no more of a car.

What happened to have numerous choices in the pocket rocket category?
Argh.


Too be fair, of course not.
The BMW's engine alone cost $17k
But also keep in mind the BMW's 300 hp and 300 tq is WAY underrated.
They dyno at:
275 rwhp
285 rwtq
as "average"
It's probably closer to 325 hp and 335 tq at the crank stock.

And it's on 8.8 psi boost, not 15+ like the MS3 engine.
At 15 psi the N54 is making 390-400 hp
with 340-350 rwhp and 360-370 rwtq
It's a stout engine.

But you pay for it. There's a reason the BMW cost $40-50k.

Not to knock the $25k MS3
For the money you can't really get better performance.
But I would of hoped the engine was a bit more stout to basic tuning or modding.
It would make me really nervous to even add 2 psi boost to the engine though.
May not stop me from getting one, but if I do, I probably wouldn't tune it, maybe just add an intake and maybe exhaust if they make a good quiet, lightweight one.

Car; 2006 Mazdaspeed6 23k miles
Cylinder; #4
Damage; #4 bearing damaged, #4 rod "twisted", oil on top of 2 pistons, crankshaft endplay
RPM; 3500-4500 part throttle (shocker)
Mods; MS CAI, TS BOV, 3 inch turbo back, ETS TMIC,
Situation; just finished putting on my downpipe. warmed the car up, checked for leaks, drove 2.2 miles down the street, 3rd gear ~4k rpms slowly rolling on throttle sputter sputter KR KR and fork in a blender sound.
Warranty; no. car was put completely back to stock. dealership claimed to have found evidence that things were tampered with (they went through the car with a fine tooth comb)
Oil; oil was changed every 3k miles at the dealership, so they would have the records. although it didnt help at all.

no, i never beat on the car. adult owned and garage kept.

i hope no oil got in that intercooler i just bought from you.

i asked you why you were parting out, you said

"no, theres nothing wrong with any of the stuff. i have a baby on the way and need the money! "

i hope its at least been cleaned and you cleaned up all the other parts you sold. intercoolers can be soaked in solution anyone? to ensure cleanliness?

pwnd

the oil was on top of the pistons because the rings were also damaged. i inspected the tmic for oil and found none. my turbo wasnt blown, nor had it ever smoked, but on these cars oil in the intake tract should be no surprise anymore. all the parts i sold were in perfect working order. the only damage to the engine was internal, it wasnt some fantastic explosion that covered all the parts in oil/coolant. the reason i sold them is because of the baby on the way, otherwise i would have kept them and rebuilt it.

How many of these blown engines had oil catch cans, theres theory the pcv valve dumping oil into cyl and hydrooil locking rods

Just wanted to update the list a little, since a few have blown just this week:

Realgib3

Target: STI
SLS MS3

That's 10 more in just a couple months.

this shits fucked up

I seriously feel bad for you guys, but I am so glad I dumped my MS3 before the same thing happened to me. It seems more & more like it is just a matter of time with these cars. Ten people in a couple months? Good god...

Is the original post being updated anymore? It feels like a lot posts to sift through to get the pertinent info.

It's so funny how down on this car everyone is. I'm done with mine but can't offload it lol.

Laloosh is right. Rock it stock or watch it blow.

edit**

Has anyone managed to wreck an engine with forged internals yet? I would go read, but don't feel like it at 4AM.

Closest I've seen is this:

http://www.mazdaspeedforums.org/foru...-cursed-15469/

Hate to say it guys, but I'm damn glad I got a new WRX instead of the MS3 I was minutes away from buying (driving to the dealership when I decided to stop at the Subaru dealer again on the way over).

That's just messed up how many MS3 engines are blowing and it seems for almost no reasons at all. I'd understand if these were almost all happening while moderately or heavily modded and were being track driven all the time. But damn, even lightly modded DD's are blowing. That is f-ed up.
And again, Laloosh was right. Thanks for the heads up on that too bro.

laloosh hasn't offered this forum shit since he left, except his own arrogance. fuck his advice.

I disagree there. He advised me to look around here and in doing so, I found the amount of blown engines the MS3 has gotten from simple basic modding. He very well could of saved me thousands, as without that tip I probably would of gotten the MS3 and knowing me would of flash tuned it and very well could of ended up being a victim of a blown engine.

Sure that can happen if/when modding any car, but it seems to be an very unusually high percentage of MS3 engines doing so. I wasn't willing to take that chance on a very basically modded car (especially how few MS3's there are on the road).
Makes you wonder how many have blown that the owners aren't even on these boards so nobody knows about them??

Those WRXs have a laundry list of issues as well.

Not really.
The first month or two of production the 09 WRX's had an ECU glitch that caused some issues, but that was immediately sorted out by Subaru. Which is somewhat understandable since after the 08 WRX was a big mistake, they pretty much quickly stuck the STI's turbo into the regular WRX to rectify their 08 mistake. No issues since the first couple months 09 production now that they've had time to sort it all out. They also beefed up the 09 tranny as well. Even though the STI's is bulletproof and the pre 09 WRX's 5MT was quite strong. Many stage 2+ WRX's on stock trannys still.
And considering there are probably 10x the amount of WRX's running around, of which 20x more are modded well beyond what most MS3 drivers do, relatively speaking there's no comparison.
I don't know if I've ever seen a MS3 at the drag strip. Every time you go you see up to 10 WRX's of various levels of mods, dragging the cars like crazy and I've never seen one blow.
The WRX is super stout by comparison. Short of a few cars over the years (Supra, some Honda's, etc) being able to take a beating no matter what you throw at it, all will have some short comings with modifying, but I don't know if there is a car that's been more often modified than the WRX and EVO over the past 5-6 years. Sure the EVO's engine/drivetrain was even stronger, but the WRX's 2.5 has taken a beating. If it didn't stand up well, people surely wouldn't keep buying them and modding them.
But this thread isn't about what the WRX can take.
I think the countless Subaru tuning shops around the country can verify and validate what the 2.5 is able to take.
Maybe Mazda will eventually beef up the 2.3 engine and these issues will go away.

Driver72, take your WRX and FUCK OFF! to a Subaru forum.

I call for BAN Hammer, the guy is obviously trolling at this point.

i dun give a fuk i have a mazdaspeed6, u can take ur subaru boy toy racer and shove it up ur asss!!!!!... speed3 still won the comparison vs the wrx =)-

theres two guys that live near me in another building each owns a sti. i saw them kissing yesterday when i got home from work, always wondered what the pink badges were for on WRXs freind told me it was some jdm shit. to me its more like
J-erking D-udes M-eats. bet you got some pink jdm badges on the way driver72. way to be a trendy fag. GTFO

Enjoy the car. I almost got one of those back in late 07. The glass tranny and higher price pushed me to the MS3. Nice to hear they improved the 5M.

I'm still faster from a roll... And if your so sure you saved money, how come I could blow my engine twice and still not be paying what I would have for a STI... sounds like LaDouche COST you an extra 15K... Bitch.

I paid $25,341 for my WRX. that's $499 less than MSRP for a 2010 MS3
How does that cost me $15k?

I wouldn't pay $38-40k for an STI either, I'd get a 135i way before that.

Boy lots of defensive people on these Mazda forums. Easily upset and argumentative. Lots of childish name calling, aggression and very unfriendly towards others. Maybe that's what Cobb meant in their post about Mazda owners that caused Cobb to stop further development to Mazda cars....hmmm.

That's too bad, I actually still like the MS3 very much and feel with a more robust engine could be an even better car. As a car enthusiast, I like all cars, and often meet up at meets with many people in various types of cars. You guys seem to be all about the MS3 and say "F off" to anybody who owns anything else. I'd hope theres at least a few MS3 owners who are cool enough to want to meet up and compare cars.
I'd look forward to seeing how the MS3 does (and see it beat me from a 40-120 mph roll).

Oh and your car is faster from a roll in the dry at higher speeds only :D

Sorry guys, didn't mean to take this thread OT.
Back to talk of blown MS3 engines only please.
Cheers.

Um, lets not forget about the 1000 page thread on nasioc about the blown motors the 09's are having. Their engine problem was 1000x worse than ours and many are still blowing. The only upside is that they know exactly what the problem is and probably fixed it by now.

You're probably referring to this:

2009 WRX engine failure VIN/build date owner list - NASIOC

It was an mfg problem that was fixed after a couple months of production. All motors were covered by warranty.

Fucking hell man, I can't believe driver72 is still posting on this forum.

Seriously, do us all a favor and go jerk off all over your new wrx.

This fucking guy, he thinks we're out of line. Just because you say something in a calm and collective way doesn't mean you aren't being a disrespectful asshole.

You and Loosh should fuck, sounds like a perfect match.

I move for ban hammer on this ass clown.

Car; 2006 Mazda Mps 6
Cylinder; 3
Damage; Blown engine. Hole in block #3 cylinder.

LOL, kids, when they want to act all tough and feel good about themselves, they just cuss and swear and insult others over the internet. LOL

Freshman year being a bit tough for you?
Wanting a "favor" of me by jerking off on my car? Wanting me and Laloosh to have sex. Sorry not into dudes and would only jerk off for my wife and some hot chicks. No "favors" for you.
If you haven't come out of the closet yet, you might as well now.
No can you at least stay on topic of blown MS3 engines. PM me if you feel the need to send insults and use 6th grade language.

mods? miles? events leading up to it?

I guess ill finally post my blow. Engine went earlier this year, spring/summer 09.

Blink
Car; 2007 Mazdaspeed 6 19,xxx miles.
Cylinder; #1?
Damage; none visible
RPM; 4500rpm, accelerating under WOT.
Mods; CBE, cobb SRI, turbosmart BPV, stock boost
Situation; accelerating in 2nd gear under WOT, heard a lound "pop" like all the boost blowing off at once. popping sound followed by screwdriver in a blender noise.
Warranty; returned car to stock minus the CBE, new engine covered under warranty.
Oil; full synthetic, changed at dealer.

intake, cat back, and bypass valve. those are pretty minimal mods for a bent rod. at least they covered you though.

He edited his post...

Yea.. that sounds like a lemon to me if thats all you had done to it (and hide the pizza intake mod from us). Glad they covered.

Laloosh is saying 'rock it stock'... I was under the impression that a few people had blown stock as well?

I know I did have some funny issues when I was stock... odd stutter/backfire, and some bad KR a couple times accelerating on the freeway...

damn blink, you blew after i sold you the AP?

This thread is making me depressed. I just bought a 2010 Speed3

should have done your homework.

Keep an open perspective. The number of motors that have popped are a small percentage. The car is actually pretty impressive. The support from North American Operations is at best incompetent. Just be aware that Mazda NAO will be looking for any reason available to void a large warranty claim.


Keep it stock, drive it safely and sensibly and good luck. If it fails be prepared to stick by your rights. Stock motors have failed too.

and keep looking here for new updates!

Like the many members have said, this post makes a lot of members worried. I just picked up a 2010 ms3 and I would hate to have to deal with a blown motor (the hassel going to the dealer and hoping the claim doesn't get voided for whatever reason)

I haven't seen any 2010 blown motors (probably too soon to tell) but do you guys think Mazda would have fix the problem with the 2010 models????

Mazda accepts no official responsibility of a design or manufacturing defect for the MS3/MS6/CX7 motors.

Mazda did replace my motor under warranty though.

No.

Blown Engines MS3
 

So mazda isnt covering most of these blown engines under the 5 year 50,000 mile warranty? or is it because people arent returning the cars back to stock before taking them to the dealership???

Usually the dealership makes claim that modification cause the damage. Even vehicles that have been returned to stock have been denied as Mazda claimed they could tell it had been modified.

I showed up to the dealership with Sri, tbe and bpv still installed and they warrantied my engine. It really depends where you take your vehicle.

what do u guys think this is i got oil coming up bad threw dipstick i think the crankcase is cloged what can be the couse

Obviously pressure is building up. Either your rings or head gasket are passing badly or like you said above, your PVC (system) is plugged. I would start by removing the PVC setup and running a straight through hose to see if it stops. If it doesn't, get a compression/leakdown test done.

Just a couple ideas.

I wouldn't try that. You will blow your dipstick out.
The PCV valve should prevent boost from getting to the crank case, if it is damaged it may not. If you remove it you are filling your CC with boost.

Try:
1) replace PCV valve with new one
if that doesnt fix it
2) compression/leakdown test

So All these blown engines are freaking me out a bit, is it happening on the modded out speed's, and whats and EDUCATED response to why these are so "common"

it happens to modded and stock speed3's. Its a design flaw inside the engine. supposably mazda fixed it or made it better in 08.5 and up

I ran without a Pcv for months. My dipstick never blew out. If it was failing to open however, it would prevent pressure from leaving the crank case. Your air intake is always at atmospheric pressure or vacuum. It may see something slighty above atmospheric (guessing less than 1psi) when the bpv opens.

It is more likely blow by from rings not sealing properly causing his dipstick to blow out.

With the Mazdaspeed3??

Yes, with the mazdaspeed3.

What specifically changed on the 8.5?

they tightened up some clearances to prevent crank walk or some shit.

Hmm, I still lean towards Lex's theory of the injectors spraying fuel on the far cylinder wall. It made sense considering the problems I had.
