I am asking because I am dealing w/this issue, which MB says is normal, but I do not like it. Oil vapor gets to intake manifold and coats it, good thing my EGR is unplugged now and no soot can make it to the intake anymore to mix w/oil vapor and form sticky goo substance. I have been dealing w/small leak from the gasket (part #59) between intake and so-called mixing chamber ever since I purchased the car. It is fixed now (after friend made me ticker gasket), but I had the opportunities to look inside the intake while changing it and I do not like what I found – black sticky substance (like tar) above the junction between charge pipe and EGR cooler.
I even replaced the Cyclonic oil separator thinking that the pressure control valve is not functioning properly, but there is still some oil into turbo intake. "
Actually I did notice oil in the outlet tube of the separator. It had a nice coating inside of the tubing, and it was very apparent that liquid oil is getting through. The cyclonic separator is faily effective, but certainly not 100% under all operating conditions. I may actually incorporate a lower intercooler air bleed line(1/8" ID) in the lower intercooler much like I did with my TDI to ensure that a slug of liquid oil never enters the intake tract causing hydrolock or runaway.
I am also partially concerned about the coating of oil and soot in the intake on mine too especially as it relates to the swirl flap functionality. I have read that malfunctioning/sticky swirl flaps can cause sudden onset of rough idle, and other driveability problems. I want to do my best to make sure this doesn't happen to me, and perhaps reverse some of the buildup that may have accumulated so far. Part of the solution seems to be deletion of the EGR and then the other part would be reducing CCV oil vapor entering the engine. How did you delete your EGR by the way?
