I would expect that, given the mileage. Still no word on a rebuild kit? Why MB made these in plastic??? How much buildup do you have inside the intakes?? Like I said, Europarts SD.Fun day yesterday. Got the turbo and intake off. Turbo came off a lot easier once I removed the rear crossmember and tilted the engine/trans up/down and disconnected the DPF. There is a ton of play in the butterfly linkage. One in particular opens at a rate of maybe 20 degrees less than the others because the round socket was so worn.
Frat house, you are going to be in good shape when you are all done. The "separator " you mentioned was probably a large factor in your consumption. If the rubber is torn or hardened it will allow oil mist in large slugs to intake. Was the egr gummed up?Still no option for a rebuild kit, got my intakes ordered today. I also pulled apart that oil separator thing. The rubber diaphragm was hard and had about a 3/4" slit in it so got one of those also. If some of those butterflies aren't opening all the way then what's happening to the extra air not being allowed into the chamber? Is it possible that some fumes are being forced back out through the intake system? When I drive with my windows down I get fumes in the cab so I thought maybe some fumes were floating around under the hood. I already fixed the seal for my cabin air filter and that stopped most of the fumes getting in with the heat on. Just now only when the window goes down I get fumes inside. The buildup wasn't too bad, more than I want to see but I expected more with 500k.
