Dealer replacing my smoking turbo under warranty. Just got car not too long ago and it's my first turbo charged car (got rid of my g35 sedan, darn happy i did too). Wondering what kinds of things I should ask about what they are replacing. (By the way the service manager didn't even know what the pcv system is, let alone what it does). Also want to make sure I have preventative maintenance under control. Gonna install catch can and get a turbo timer.... Any feedback would be awesome, I just don't wanna walk away with a new turbo and find out 6 months down the road that my intercooler is shot due to the leaking oil... and I don't wanna f this one up.
