hello, I have a question about my 400 6.6 liter W72. I have a super bad oil leak, it is coming from somewhere on the top of the engine. I put a new distributor on a while back and when I did there was no gasket on either the old one or with the new one. My question is, should there be one? I mean my oil leak is bad, it is hard to determine where it is coming from though. Also the piece under the intake that covers the engine center looks to have no gasket, but some sort of sealer between it and the block, but it doesnt appear to be leaking there, but like I said it is hard to tell. Any ideas, there is like a pool that forms on the top of the engine behind the dist.
