I have two oil leaks on my 240. I have already identified one of them to be the drain plug in the oil pan but the other has me stumped. I searched the forums on here but none matched my problem. It is on the back of the motor. I have checked the valve cover gasket and its not that. The rear main seal was replaced 10K ago so it shouldn't be that. Is there anything else it could be other than the pan gasket?

 

nope thats it.

 

if u really want to find it u shud steam clean the engine....get it as clean as u can in the oil areas. then go to kragen or any auto place to get oil dye to....it has direction...when u put it in, run it hard and look 4 the leak again wit a black lite a special glasses...if u have them....if not, u could see the oil anywayz cuz it shud be clean so u'll c the leak. hope this helps
