I have an oil leak in a '86 300SDL with a 603 engine.

I seems to spray up on the inside front of the hood on the passengers side. Then it drips down on the air filter. The fan and the front of the engine have no oil on them. The only thing in that area that might have oil in it is the breather pipe from the valve cover to the air intake hose.

Anyone else have or seen this problem?
