I have an oil leak running down over oil filter, cross members, exhaust, bell housing and transfer case drive shaft. Any ideas where it is coming from?

There is no way of knowing without cleaning everything first.


There are many places it could be leaking down from.

 

Oil pressure sensor

Rear of the valley plate

Rear main seal

Rear cover gasket

Oil pan gasket

 

Those are just a few places it could be coming from. You will need to degrease and clean everything up and watch for the spot the oil leak is coming from.
