(Re-read Friday's message. Apologies for typos etc. Guess the Percocets were kicking in... Good thing my 5th grade English teacher wasn't here -- she'd still be slapping me). In the daylight can see that I've got two different colored valve cover gaskets. Driver's side is white, with no protruding material. Passenger side is black. Material protrudes slightly on long sides. Is as hard as plastic (may have been rubber at one time, but it isn't anymore). Used additional spacer washers to ensure maximum clamping pressure before bolts bottomed out. Appears to have tightened driver's side, but passenger side still leaks badly. Will kill engine with steady steam of carb cleaner. Bought a FelPro gasket set today. Not the thickest rubber in the world, but at least is flexible. Will see what engine thinks of them. Timing case gasket is definitely rubber, and is still flexible. Spaced bolts and retightened anyway. Doesn't appear to leak. Moral of the story (assuming new valve cover gaskets do the trick): all my proselytizing about not driving around on 22 year old rubber goes beyond tires and hoses. If it ain't made out of aluminum, replace it. Speaking of PRV's -- if I understand section D:06:03 of tech manual correctly, ENTIRE block is vented through PCV. This means that NO seal can be taken for granted. Even gaskets that just drip oil on other engines could be letting air in. What a refreshing piece of hardware...
