[QUOTE="Flyer58, post: 433569, member: 18629"] I'd still pull the valve cover off and see what scary sights there are. That little brass fitting with an orifice probably can't be cleaned with spray cleaner or any additive due to the way it's hidden inside. As I recall it was hidden inside or under one of those towers you'll find on the inside of the cover. Mine was caked with a baked on layer of crud. Generally, higher crankcase pressures will cause more oil to get sucked into the valve guides. I used a good Felpro gasket. The previous owner used a full tube of silicone and made quite a mess and if not done right can clog your oil passages. [/QUOTE]
