Yep; the whole purpose was to figure out what the commonality between pops was. Now we know (mostly) so this is just ancient, painful history at this point.

MY engine blew up this morning, VVT broke and dealer told me it affect the pistons and valves. Estmated cost 7800 for new engine and warranty.

Does this sound reasonable.

See signature for mods. I really want this car to last it is my daily driver. I use royal purple change every 4k miles.

also looking to buy an engine if you have any leads please let me know. I do have mazmart searching for me but they told me today they didn't see any inventory. any leads would be much appreciated.

Chain broke? Or vvt?

Sorry to hear!!! I'm going through this as well. Mine Blew late January. Very cold out 5*! Normal driving 3rd gear around 3400rpm. Hypertech, CS TIP, Forge BOV, CS SRI. I got a brand new long block from Mazda in Delaware for $3350. $225 for a new oil pump. I was quoted at $1200 for labor. I'm thinking it will run more like $1500. So I'm around $5000 all in. They are also throwing on a CS OCC. $7800 seems steep for a stock motor. For that money you should be able to get a full build! My MS6 should be finished by next week. I really love this car but I'm scared now! It's my daily driver. I'm worried about the HT tune but have read this is very common in stock tune. I'm thinking the AP with a custom tune is the way to go to be safe. I don't want to go through this again!!!

IIRC the Hypertech tune adds lots of timing and runs crazy rich....

I agree. Chain broke. I may dump the ht and stay stock... Waiting for estimate for repairs so I can review fully. 8000 also covers oil pan and coolant. I somehow my oil was low. It has never been low. I estimated shop time about 20 hours I am told....

Then it's not the tune... it's just one of the classic timing chain/VVT failures...

Classic... This is the first time I heard of it, but argh

bad vvt and bad chain are independent of each other.

Why is the dealership involved at all? I mean if they're not covering the failure under warranty, why waste so much money? Just take it somewhere else or do the work yourself.

I blew up about two weeks ago. Im a 2012.

I turned a corner slow and at about 2500 rpm i throttled into a WOT pull in first gear and right around 3500-4000 rpm i shot a rod out the motor both front and back side.

Tune was my own targeting and hitting 21psi at 3500rpm to 4500rpm before tapering down to 17 by redline. Timing was at 2 degrees at 2 load at 3000rpm. However calc load was targeting 2.38 at 3000rpm in all gears except first. First gear was targeting 1.3 calc load at 3000 and tapering up to about 1.6 for more wheel spin control.
Currently in the process of stocking out before a visit to the dealer. Really need this to work. Supposedly my damage was done way in the past. I have run E85 maps with lots of timing in the 3000rpm range somewhere up around 6-7 degrees has been used in that area and i have had maps that have run 10 degrees at 4000 on 93 without KR. Anyways i have a Thread in nator new england with logs virtual dynos and maps that have been run on my car...dont use them if you look at them obviously.

i blew up my engine months back and threw 3 rods. all bent. put in k1 rods, wiseco piston bored 20 over. my question is, has anyone blown or bent a forged aftermarket rod?

Only one person that I know of has bent a forged rod. coolant got in the cylinder due to the head lifting which caused the failure

Edit: and obviously of what cld12pk mentioned happens, no built/forged rod is safe

Yes it has happened. A bad tune or hydrolock will own any rod/piston combo.

makes sense. thanks! reason i ask is after breaking in the engine i did a few slight pulls and it all seemed fine. i do know that my turbo smart does need to be tuned and all that but last pull i did, i had a massive backfire and it sounded like it was up front. all boost pressure dropped and i thought that i developed the infamous clutch vibes again. did more boost pulls a bit later and no problems. at that time, absolutely no kr reading even at the loud pop. reading 0.00 degrees the whole way. no drop in mpg or any of that. just had a massive scare and just worried cause i have no clue what that pop was. any ideas? and what should i do to diagnose? compression test, leakdown test and verify measurement of my rods? or is there something i can log on my access port ?:grumble: car has solid mounts so there is always vibes on my pedals and i have a bsd. vibes on the clutch are the same as break pedal and gas pedal. to be honost i completely forget how the original clutch vibe was.

also dealing with a blown motor from what i think.... coolant line ruptured due to how tight the CPE TIP fitting was.... my temp sensor went bad and blew a head gasket and my shit is seized up. opening her up tomorrow to see the full extent of the damage..... whos got a spare motor? got cash in hand!!!

fuck u mazda
 

so I had a 2008 mazdaspeed 3 with a sure auros 3 sri +tip and a synapse dv and just yesterday I hit 79,563 miles my engine blew

second cylinder fuck u mazda that is bullshit

Sorry for your loss. Was it tuned? If it was running a 3" intake it needs a tune.

If he managed to get the AP and HPFP internals he bid on here then yes he was tuned:
http://www.mazdaspeedforums.org/foru...ml#post2143825

That's a pretty short window to blow a motor in.

it was the si so the intake did not need tuning so bummed now selling the car

If it had a 3" maf, and wasn't no maf cal, it's safe to say that's why you blew.

Soooooo it was a Civic? That's the only reference to si I can think of. As has been pointed out, if you had a 3" MAF, you needed a tune.

go on the sure motorsports web page look on intakes u will see a full 3 gt300 or the si i have the si i bought it so i did not have to tune my car

we don't go on sure's website, so i have no idea what an si is, but if it had a 3" maf housing, then it required at the very least, a maf calibration.

Si is the standard issue which requires no maf calibration. It is not a 3" ID.

ah
in his op he mentioned aeros 3 si penis eating.

If you believe SU when they say no tuning required, you've embarked on a boat of fail regardless. Always sad when an engine blows but someone who comes here just to post that their horribly engineered engine blew without knowing fuck scrap and blaming Mazda invariably results on having to file this under Another Fucktwat Who Cries Like A Babyseal Being Slaughtered Because He Did Not Care To Understand What The Fuck He Was Doing And Dreamed About Being The Prom Queen.

God I fucking love when @Tomas; rants!

@Fobio;
Post your blow, yo.

A lot of people blew their motor because they think its a civic it doesn't need tune

Did he really or is this moar Canuc on Canuc gheyness?

I quote. "He hit 1.55 lateral g and starved a bearing. We're going dry sump."
Have fun with THAT.

And for how long does a car need to sustain 1.55g to starve a bearing FGS?!

lulz.

We had better ask a gearhead.
@Fobio;? How long you hold 1.55g, fighter pilot?

this thread worries the fuc outta me... mines about to hit 120k. i suppose there is no simple way to inspect my engine without pulling it out. Damn so many blown engines. Would it make a huge difference to just put in forged rods/pistons?

Umm, there are a few ways to check your engine while it is still in the car.
1. Compression test
2. Leakdown test
3. Piston height test

Forged internals would be better than the stock internals but you might as well do a full rebuild.

Ok so my speed is skipping on cylender one and i think. it is the valves
