im trying to help a friend with an 82h504 d5. he says his engine oil level keeps rising and states it is his clutch oil getting into the engine. does anyone have any insight? seems like i remember these not having a rear main seal but having a scavenge oil pump to keep the right amount of oil in the clutch.
I have a failing memory, something comes to mind the rear engine seal had a significant update to overcome this problem, the seal installation required a special tool.
