Blue Smoke

[psievers]

I am getting blue smoke coming out of my exhaust in my 09 CX-7. What's going on? (headshake

Blue smoke=Burning oil. Take it to the dealer. Is it turbo?

Turbo is gone. Mine went out at 25k. Blue smoke started pouring out while I was picking it up from being serviced. The tech told me immediately that he needed to order another turbo.

That's what I was thinking.

dealer report

It is a turbo (only 6900 miles). The dealership said I need to change the weight of the oil, which is what he did. The smoke stopped for a little bit, but then came back. I called him and he said I need to wait at least 6-8 weeks for all the old oil to get through the system.

Hmmmm (gah)

6-8 weeks is BS. Maybe 150 miles

What?!?! 6-8 weeks to get the old oil out of the system?!?! Seriously? That service writer is an idiot. I'd talk to the service manager. You have 5 quarts of oil in the car not a few hundred barrels. It's not like the oil has a very long path through the engine. If they drained the oil you *MIGHT* have a 1/4 of a quart left in the engine, compare that with the ~5.5 quarts the car takes to fill back up, that 1/4 of a quart of old oil isn't going to affect anything.

Sounds to me like they fed you a line in hopes you would go away or that someone else would get to deal with your issue.

Call the dealership or another one in the area and ask to talk to the service manager. Tell him that there is a TSB for the smoking turbo and that you suspect the turbo the be defective. If none of the dealers want to fix it for you call Mazda north America directly and take it up with them.

not happy

Just spent 3 hours at the dealership. They could not reproduce the blue smoke and thus did nothing!!!! (uhm)

Trick is driving in traffic or letting the car idle for a long period of time. Did you recently change the oil? If you used a different kind it may have bandaged the problem.

The weird thing is you have a 09, the bad turbos lurk within the 07-early 08's. Hmmm?

 

[erhayes]

Was it really blue, like when burning oil? I bet the dealer put heaver oil in to mask the issue. A 5w40 was used on 07s to test the turbo and if it still smoked then the turbo got changed. I thought as others did that turbo seal issues were resolved in late 08 models.

 

[psievers]

Dealership changed oil to synthetic oil. I believe this is a short term fix until they have a solution to the problem.

Please post back with the results.
