This is a common place for oil leaks, this article shows how to replace the o-ring. The only real trick is to rotate the cooler as you pull it out due to clearance.


Other common places for leaks: valve cover, egr weep hole, engine block breather hoses, oil pressure sender. My oil pressure sender was actually leaking out of the middle of the sender. All fixed now.
