So I found out I had an oil leak on the XJ the other day. Its only appearing under load and its hitting the exhaust causing smoke of course.
Today, I managed to get it up on some ramps and ran the engine up to 2500 RPM to discover, its leaking from a weird place. Its coming from the drivers side along the dust cover of the transmission housing. And yes, I am 100% sure its oil, not ATF+4.
I have already replaced the oil filter o-rings, valve cover gasket, oil pan gasket , so that leaves either the rear main seal or something else.
Anyone have any ideas?
Here's photos too!
