Ok, this weekend I installed a weber in my YJ (whoohooo) already can tell a diference, runs great. Real test will be tomorrow morning at 06:00 when it is really cold.
I also replaced my cracked POS plastic Valve cover with a new POS Plastice valve cover. The old Cover was leaking, but so is the new one. I got it from JC Whitney and it came with a Foam/Rubber type gasket that said do not use any sealents so I didn't. I snugged all the bots down (came with some self tapping for the passengers side) but not too tight for fear of cracking this one. What do y'all suggest next? tighten them some more or go with another gasket or just use RTV?
I really wanted to get an aluminum cover but budget was tight with the weber install and didn't want oil blown all over my new weber.
