oioifrollix Posted June 19, 2014 Share Posted June 19, 2014 Hello all, I am a proud new owner of a '87 2.5l 4X4 4-speed. I recently picked up this MJ in Albuquerque, NM, and immediately drove it home to NH coast without a single problem along the way. Well, there was one thing...the valve cover leaked a little. Today I replaced the valve cover, using a little RTV and one of those rubber gaskets. I scrubbed the hell outta the cover, getting all the years of gunk out of the two pathways where the two hoses plug in. When I started it up after replacing the gasket and letting it sit for 6-7 hours, It sounded terrible...a low stumbly kind of idle, with very strong exhaust fumes coming from seemingly everywhere. I visually checked for leaks, but i couldn't find any apparent ones. I also changed the oil today, and the truck took about 4.5 quarts. Is there something I could have knocked loose or something else that needs to be cleaned after clearing those ports on the top of the valve cover? I am at a loss here. I;m gonna let it sit over night and check all the seals again tomorrow. Any advice would be much appreciated. -Frollix Link to comment Share on other sites More sharing options...
