Oil leak under intake manifold! Engine M104
I have had all the typical oil leaks in my E280T 104 engine from 1994. The head gasket, the timing chain cover (top and lower part) and have managed to seal them. But I still have oil on my garage floor :-( The only place I can see oil now is in the area directly under the intake manifold, close to the head at the rear part of the engine (between the oil filter and the intake manifold). Does anyone know any particular source for this oil leak? Could it be the head cover seal?
