1974CJ5 Posted December 6, 2010 Share Posted December 6, 2010 I have recently rebuilt the engine in my 87 2.5 MJ because of a broken piston ring on cylinder 2. Everything worked awesome, except my head gasket is leaking a bit under the back right corner against the firewall. I had the head resurfaced, no warping detected, block was professionally cleaned, used a felpro gasket installed dry. After this problem began I starting reading in a haynes manual that composite gaskets shouldn't be used. Well the only gasket I can find is the same felpro gasket covering 85-2001 jeep 2.5 engines. The haynes manual says that 87's should only have a stamped metal head gasket that should be sealed with copper sealant. Does the felpro gasket supersede this? What do you guys think? Should I be looking for a different gasket or is there another problem? Note: I cannot detect any white smoke in exhaust or coolant in oil (yet). I am reasonably sure that it isnt the freeze out plug on the back of the head. Quote Link to comment Share on other sites More sharing options...
