My engine is using more oil than it should!
 

I will start the story about when I first bought the car in middle of Oct. I left the private dealer and took the car to Mazda cause the turbo was bad (long story short). They wanted me to find poof of receipts which I explained just bought car and had no proof so they said will have to drop car off and they will take pics of inside engine and send to Mazda.

So I drove for a big smoking week or so and dropped car off. Told them about the cold start engine noise and loud tick/rattle noise when engine was cold. Couple of days later service writer let me know the pics of inside engine was very clean and they ordered the turbo, timing chain cause it stretched, a tensioner cause that stuck and was the cause of t-chain stretching. And a vvt actuator.

This was all replaced in beginning of November. After they replaced all of that and I had them use my own synthetic oil 5w30. Btw the car had 54k on it when I bought it.

The beginning of Jan. I was about 4k since my oil change and noticed the car seemed to lack power, I checked oil level and found it was not on the dipstick! I added and added and finally after 3.5qts. I kno, I already kicked myself for that stupidity but I did not think this car would use that much oil. Anyways checked my oil a week later and was about a 1/2 qt low again. Just had my oil change done a little over a week ago and let them know at the dealer about my car using oil so they have it on file. They told me to keep a eye on level and bring back if low and not to top it off so they can record level being low.

I checked my oil level before going on dyno Sat. And of course 1qt. low. But I still dynoed it and brought to dealer afterwards (only 400 miles since oil change was done). They checked oil and topped off and I need to call Monday to see what the next steps are. I will keep you guys posted on if Mazda does any inspection or repair. Putting back in stock form for now.

Letting you guys know. I know dougefresh wanted me to keep him posted so I added you guys from dyno day.

How much crap are you collecting in your oil catch can? Doubt you have one, but you should get one.

I have one but have not installed yet. I had bought off of block8head. Was going to wait until spring and install when I installed all the other bolt ons I have. Just waiting until the weather got warmer. I was going to ask for the dealer to pull a oil sample and have it tested but it was too late when I asked and the oil was already drained. My old co worker at the dealer suggested to put back to stock form in case Mazda wants pics of engine, etc. that way I do not get turned down for warranty. The coolant is clean, intake tract has quite a bit of oil in it and the exhaust tips are always covered in soot/ carbon. Possibly the rings in the engine.

Don't try getting warranty repair while modded

I only have the intake, tip on, removing tomorrow. Already uninstalled the ap yesterday before bringing to dealer.

If they are looking at your engine and you had an AP installed you might be fucked. They can see the AP was there using invisible tables and shit.

Mazda has access to shit we don't but maybe ul get lucky and they wont see it. Either way- good luck.

I heard they can check key cycles and If I had to go far enough to defend my case I would say my gf killed my battery having the key left on listening to the radio. Lol that would clear the key cycles that they would look for. : D

well keep us updated on any new news man.

Well I called and talked with the service writer today and now am basically waiting for the tech to contact mazda support to see what they want to do next. As soon as they find out what they want to do I will have to drop the car off and leave it with them. But for now just driving it stocker form. The tech said when I spoke with him Saturday that it can be quite a few things. The breather system, piston rings not sealing good and oil may be getting by them was a few basic things he mentioned. It would be nice to get a new engine out of the deal! A few guys told me if that was the case it would be a genpu updated engine( I am not sure what the overall difference is with my ms6 engine compared to the genpu engine) can anyone fill me in on this?

Didn't get the mention, wtf. Just wanted to say good luck my man! Your going to need to trim that whileline rsb. Ask @Block8head about it. It's not a huge deal, but iirc it won't just line up and fit.

so whats the word on this man?

Was called this morning from service writer and was told that Mazda wants me to replace the pcv valve and then check the oil in another week and see if the oil level is still dropping. So I went to Mazda parts and ordered the pcv valve. I will let you guys know what happenens next will probably be another week or so.

They are not replacing it for you?

No, that is considered basic maintenance.

for basic maintenance they sure put it in a hell of a spot.

^Yup. It is the little cunt that had my wife's CX-7 on ramps for 5 days of Hell.

Update! I picked up the pcv valve and now I am just waiting for the weather to become warm enough to try and install it.

I tried last night after work when it was about 25 degrees out. Was not a good idea. I can actually get my hand on it with no jacket on, but that was about it. When I was looking at it with my mirror it looked like there is a plastic ring or lock on it which I am guessing to keep it locked on while under boost to prevent it from popping off.

I really do not want to remove the intake until I am swapping it out with the p&p one. Any tricks anyone do to get it out without removal of intake???

I can't imagine getting the pcv valve off w/ the mani on. Maybe if you cut that retainer clip off, but idk. You can buy that black plastic clip you're talking about separate. There's a pic of it in my how to (where I take mani off):

So, are you getting a new motor or not?


:/

At this point I think they are trying to have me replace anything non warranty and see if I give up on this ongoing issue. It is going through a quart/ week. Right now I have almost 59k miles on it. Hopefully after I replace this pcv valve they don't give me any shit about past warranty. Especially since I complained about it at around 55-56k miles. I will update when I find out anymore or when I put in the pcv valve. This is a good way for me to keep a log on date time and miles as to what I have done so far.

Did not install pcv yet but went to go to work today and find a puddle of oil under my car and opened up the hood and was all over the pass side of engine compartment and front bumper, found dipstick popped off of tube about a inch or so. Not sure where the oil came from. I am not sure if it was from dipstick tube. I had to leave for work so I did not have time to diagnose. I called dealer and told them I will be having it towed in morning. I hope and pray they don't blame it on pcv valve. If so I will be paying the bill. I ended up driving my motorcycle to work. : /
I still have not swapped over my stock intake. Thinking I should do that now since it is going into dealer.

yes, like our mother fucking cabin air filters. jesus christ.

i'm thinking imma replace my pcv and clean my valves/im when the weather warms some..
with the im off, i'd imagine the 'ol pcv replacement is cake, yes?

@darkcherry man, they are giving you the run around. i have no idea, but it seems feasible that a blocked pcv might cause enough pressure to push the dipstick and oil out.. seems far-fetched, though.

how much are they charging you to do the pcv?

What a bitch it is to remove the intake. Wtf. Attachment 51963

Hppe you got the retainer clip and o ring too. That retainer is a motherfucker, and I was glad I was able to just break it off. o-ring is inside.

That sight makes me angry. I broke my PCV a few weeks ago being a dumbass. It is a motherfucker to get to. Just pray your PS pump fits right back on.

Well I found out turning it ( edit) clockwise! and it came off. I luckily did not break it. But I did manage to pull the a/c compressor wire out of connector and will try and recrimp or try and solder wire into terminal if I have to. Thanks for the heads up on the o-ring. Did not know there was one in there. I don't think it has a stuck pcv cause it sounds just like
The new one I am about to install. Had to take a break cause was getting pissed.

Attachment 51973With a rag over the end I can blow threw both ways and should only be able to blow through just one way. Just checked new one and does the same thing so I am guessing I have other problems elsewhere for this oil consumption problem. At least Mazda can not tell me it is not warranty.

After putting the intake all back in and the new pcv valve I now have a p2006 code that I cleared and came back again. I guess I will have to check tomorrow and make sure I did not forget to connect something. Wondering what else it could be.

too drunk to remembre what p2006 is.. I'm thinking it's Troll? LOL JK brotha, haha (about troll not drunk). Waiting for new engine to congratulate you!

P2006 is the intake manifold runner control stuck. Something is not adjusted correctly when you put your IM back on.

I did not touch any adjustments. Is there something that could have messed up while r&r ? A adjustment procedure after a r&r that needs to be performed?

vacuum tubes are on backwards on that plastic thingy on top of the mani

I never removed the vacuum lines from it.

Wow, I am retarded. I looked into my p2006 code and checked the intake to see of I forgot anything and of course I did not re connect the electrical connector for the intake. Code cleared and is gone now. Also checked oil today 300 miles after replacing pcv valve and it is still full. Will check in another couple hundred miles to see if it is still full. :chairshot:

Fantastic.
I asked someone a while back if a bad PCV valve could result in oil consumption, and was told no.
There is hope for me now.

thats good news to hear that it seems to have fixed the issue so far. i think most of us were pulling for you to get a new engine still.

Yea, I was happy but also disappointed at the same time. Still going to check in a few hundred miles. Glad this can shed some light on the oil consumption issues for others hopefully. I will let you all know after some more miles.

Did a top engine clean last night and then let the car sit for about 5 hours to help break down the carbon from the seafoam. I took a video but can not upload from phone so I took a still pic from video. Attachment 52415

I have put roughly 500 miles on the car and checked the oil late last night and sure enough it is about 1-1/2qts. Low again. Will be calling the dealer later on and see what Mazda wants to do for their next step.

Based on everything I've read in this thread, I'd ask the dealer to do a leakdown/compression. Specifically the Leakdown. Your rings are most likely shot.

-David@COBB

^^ That was the problem in my car when i had it... Did a leakdown and it was at 40% leak on cyl.3, compression low at 162psi while others at 185psi.

Shop told me it was most likely rings and it would require opening the engine and replacing the rings + more, like pistons and rods.

I went through the same BS at the dealer as far as oil level check but i did it too late, warranty ran out. They gave me a BS story on how they cleaned up the "carbon build-up" and the compression was better when they test it. Sold it the car about 10k miles later, it was fine, just using extra oil.
