Scania 164 580 .
Oil in exhaust, seems to be before turbo on drivers side, but seems to be no oil on exhaust manifold on drivers side or other side .
Can oil leak down from Turbo as that is at higher point than where the two exhausts from engine meet and combine into one before Turbo.
Why would engine oil be in exhaust like this ? It’s not coming out at manifolds yet it’s in exhaust before turbo and after turbo ?
If it’s a Turbo problem what is problem, as I’m sure Turbo is working fine. Could it be a oil drain pipe blocked that returns oil to pan ?
Or it this a common problem and best to put a turbo on, or is it not Turbo at all ?
