took everything on the right hand side of the engine apart and put it back together, I noticed there is a minimal amount of oil in front of the turbo but there is no shaft play or anything. and defenitly there is no air leak cause i checked everything
the car has improved but still i feel like the engine is restricted its not as free as it should be. tomorrow we'll have a look at the fuel side of things (fuel rail, injectors)
anyone have any other ideas??
I read something about the o2 sensor sometimes becoming faulty where is that located and can that be the problem ?
