Oil all over bottom of Engine and Transmission

Could this be because of a leak on the top or front of the engine? Has anyone else had this issue? Any common causes?

Likely culprit is the oil filter housing (OFH) gasket. $6 part but 4 hours of wrench time.

Start here (CN90's DIYs are very helpful):

Might look into other parts that might need replacing while replacing the OFH gasket.

Power steering hoses and oil filter housing gasket are the culprits when you have an oil leak on the drivers side. Passenger side oil leaks are almost always valve cover related(gaskets) Also check your oil pan bolts and see also see if your oil pressure sending unit has oil around it. Mine has a leak. It's on the bottom of your oil pan with a wire loom attached to it.

its self lubricating
true story..

some of the best old bimmers that ive seen where ones that leaked for ever... oiling the chasis, stopping rust from starting..
someone like me or some of you comes along 20 years later... snag's it for nothing.. replaces every seal and gasket it has... and has a fresh clean non rusted classic car for another 200k
