cruiser54 Posted December 23, 2011 Share Posted December 23, 2011 ALWAYS start at the top of the engine when searching for oil leaks. Rear of valve cover gasket is common. Oil filter adapter housing where it meets the block is another common leak area along with a leaking oil pressure sending unit. Rear main seal is less common but gets blamed often since the other places I mentioned above- The oil from them drips off the rear main seal area since it's the lowest part of your engine.

cruiser54 Posted December 24, 2011 Share Posted December 24, 2011 I'm sorry its the 4.0 Fine. Then the advice above applies. Start at the top using a flashlight and let us know what you see. Link to comment Share on other sites More sharing options...
STERLING STINGER Posted December 24, 2011 Share Posted December 24, 2011 check your oil filter adapter. :waving: Link to comment Share on other sites More sharing options...
64 Cheyenne Posted December 24, 2011 Share Posted December 24, 2011 Make sure your leak is not being made worse by an over pressured crank case. Meaning check your air box for oil. If the air box is full of oil, then the vent line is clogged or restricted. This causes the CC to be in an overpressure state, oil will then try to force its way out wherever it can eg: rear seal, VC, airbox etc. You might think you have a major rear seal or VC gasket leak and maybe you do, but because of overpressure, oil just pours out...

carnuck Posted December 27, 2011 Share Posted December 27, 2011 Make sure it's not ATF from the lines rubbing through at the bell housing. Link to comment Share on other sites More sharing options...
