Camshaft plugs on M112?
I have a slow oil leak in the back of the engine bay which I’m trying to locate on a 2002 W240 with M112 engine. Common suspect would be camshaft plug but I can’t feel the plugs behind the engine. Does this engine have camshaft plugs?
I’ve already replaced valve cover gaskets and resealed the breather covers. I can’t find another rear source. Perhaps I’m looking at tranny oil and not engine oil. But I took care of the major tranny leak when I did the tranny service with a new gasket and replaced the leaky plug with the electric transmission plate.
My next look will probably be the freeze plugs (expansion plugs) under the intake manifold which can apparently leak oil and when doing, leak to the rear down to the area of the transmission bell.
