It seems that my spark plug/valve cover gasket on first cyl. and on the fourth cyl. (counting from front to back) are cracked. Oil leaks into the spark plug receptacle and there's a drain in the spark plug cavity that dumps out of the exhaust side of the motor. After I did my valve adjustment, spark plugs, etc., last year; I cleaned those little holes so now they do their job of evacuating the oil really well.

Along with my valve towers leaking, I also have the rubber spark plug gaskets leaking. That's why I wondered if the head gaskets leaked oil because the holes are up there. Without a mirror and a good flashlight they're hard to see.

Once again.....Thanks for all your input.
