Like it says, my 2001 cummins auto 4x4 with air dog 150, edge juice , exhaust and air filter is blowing smoke out of the filter. Its got 205000 on it with the original turbo still on it to my knowledge.... is it a turbo?

 

Sounds like a bent or stuck valve.

 

yea but it should make a lot of noise if its bent, check the play on the turbo shaft
