smoking mazdaspeed6 at 16k miles

My MS6 started smoking badly while in a drive-through on Friday. I immediately took it to the dealer (Capitol Mazda, Cary, NC). On Monday I called asking about my car since I havent heard any news. They said they were unable to reproduce the problem and suggested I change the oil to 5w-40. I picked up the car and drove it 4 miles home. Once home the car started smoking again so I took this footage, and connected my OBD2007/ELM327 to view the PIDS. The car was running very rich (-11 LT Trim), so I left it connected to be able to show the service advisor. Once I arrived back at the dealer, the car was no longer smoking but was running very rich which was obvious by the smell alone. I showed the advisor the readings which were still connected and he suggested that the scanner was making it run rich, and could have shorted the computer. After leaving the car with them again, and me having to call (again), the dealer was still unable to reproduce the problem nor did they see a rich condition. I informed them that I was aware of a TSB (5505) where a faulty PCV valve will cause the crankcase pressure to prevent proper drainage from the turbo, which results in the oil seeping past the seals and burning in the turbine or compressor housings. The dealer disregarded the TSB and said that Mazda would not pay for any repairs unless there is a check engine light or they see the problem first-hand. After arriving back home I called Mazda customer service which was quite helpful. The woman from Mazda indicated that she would like to see the video which is the reason for this upload, and she will investigate the issue.
Its unfortunate that such a severe problem would go untreated by the service personnel and pleading with the manufacturer along with self-diagnosis is required for a resolution. However, I feel confident that Mazda customer service will resolve the problem and repair my MS6.

hey man i own a Mazda tribute and i know its a different car but i had the same smoke coming out of it and got the same run around from all the mechanics i took it to. idk if it helps but my car was finally diagnosed with bad engine coils and when they were replaced the car ran fine. it might not help but i would see if you can get the coils checked out

@boxybrown4421 Thanks for your post. Interesting that coils caused the smoke. Did they attribute it to running rich due to misfires?

Thats what happens when you drive the shit out of a new car. Thats why you take it easy until its broke in.

[soloIIman]

@Michiganman2cali I would agree that abusing a new car would result in excess wear, however in this case, I purchased the car new and observed the 1500 mile break-in period. This couldn't be attributed to mishandling the car unless the dealer abused it before I arrived on the scene.

Additionally, a car needs to provide what is advertised. You cant argue that any mazdaspeed car shouldn't be driven hard once broken in, that's exactly what was sold and what was bought.

Misleading title.

To all the people who are saying this needs replaced and that needs replaced, proper techs base theyre repairs on evidence that suggest something needs to be replaced or maybe even repaired without replacement parts, just because it worked for you, your uncle, your girlfriends mum, dosent mean it will always be the problem, diagnose and dont assume!

Plastic bypass valve needs to be replaced..

You probably already know this, but all dealerships are privately owned, they only have to fix warranty and tsb issues, they are usually ####'# if you know what i mean, there are good dealers out there but not many, I have worked at one where they forced us techs to put cars out without repair and still charged the customer. That is why mazda is willing to help, Just saying dont let a dealership change your view of a manufacturer!

@jhaze918

Yes! Thank you! So many morons go their anyway and get just destroyed in prices!

I only go if its under warranty

[chestateegold]

put more windshield wiper fluid in it. that will fix it

[boxybrown4421]

im not really sure if it has anything to do with running rich but the coils failing caused more problems including the catalytic converter dying on me twice. ya that was expensive to fix. this is one of those problems that basically you need to get lucky and have the car have this happen to you at the shop because if they cant duplicate the problem they wont be able to fix it. my car was going back and fourth between this and normal for like four months until it had the issue at the repair place
