I've had an ongoing issue with Cliff's BMW regarding an oil leak from between the clutch housing and engine. The bike was "repaired" for an oil leak last August in which all of the transmission seals were replaced. I asked them to replace the rear main seal as well but I was told that the seal was "seating well with no cracks - when I see this, I don't touch it". Within 100 miles of getting the bike back, I noticed a collection of oil along the seam where the rear of the engine meets the bell housing. I was told this was "normal weeping" and no problem existed (after some persistent inquiries, Cliff himself got very unpleasant with me). I let it go for a few months and after about 400 miles since the repair, I now have oil collecting on the lower fairing and around the bottom of the bell housing and oil pan. I again visited the dealer and was told that the rear main seal was fine and that they think the oil is coming from the back of the crankshaft cover and wicking down and under the engine. Does this seem plausible to any of you? I'd like to believe him but I think I'm being fed a bunch of BS.
