I have a 2009 Mazdaspeed3 that billows out oil smoke when it idles after it is warmed up. The dealership told me the PCV is poorly designed and Mazda is designing a new one. They told me the only thing I could do is use much heavier oil until the new part is ready. I have had this problem for 18 months now. I suspect they want to build a better PCV system to hide the fact that Mazdaspeeds are all wearing out their engines or blowing their turbo's oil seals. Mazda was replacing the turbo on cars that had the same smoking problem. For two years they have been telling people to wait for the new PCV.I don't want to wait until my warranty is expired to find out I had excessive blow by the entire time. What should I do?
