Ok here is what happen. there is blue smoke coming out of my exhaust. My friends mechanic says its not the head gasket but the turbo oil pressure line. Is this true. I really need help alot. Please please please please!!!!!!!!!

 

blue smoke is burning oil. The turbo itself leaking oil into the intake can do this. The oil feed line for the turbo can not cause that problem. If it leaks, then you have oil running down the outside of the engine or onto the turbo... also a leaking oil feed line can lower your engine oil pressure.

Or the rings are shot and oil is seeping past them. Engine rebuild will fix that.
