My 2001 Volvo S40 is blowing bluish gray smoke. Took turbo off and went to Turbo City in Orange, CA. They said all seems well, but the exhaust side is not wet with oil. The side to the intercooler is damp with oil. Could back pressure from a clogged crankcase vent system be the problem? Just don't know.
have the same problem?
