I need a little help. I am trying to cure my N42 of oil leaks. I have changed the Vanos O Rings and the Cam cover seal. I have degreased the front of the engine because I thought maybe the crank seal was weeping but it seems that it is OK. I notices a small pool of oil in the belly pan just under the exhaust near to the front corner of that side of the engine. does anyone have any idea where this could be coming from? Any help would be much appreciated. I cant get the car off the ground to take the belly pan off in-order to take a look at that side of the engine from underneath.
