Has anyone else had this leak?
Fixed all my other oil leaks only to discover I have an oil leak coming from the crankcase oil galley right where it meets the transmission.
My mechanic showed it to me when it was on the lift.
Apparently the transmission has to be pulled in order to reach an allen bolt there that is leaking.
I found a photo online of the oil galley. Just can't see the area near the transmission in the photo.

 

Genuine Oil Filter-3.2/4.0 Litre For Jaguar Xj 1995 - 1997 (from 720125 To 812255) Classic | Jaguar Land Rover Classic Parts

The finger is pointed at the oil pressure sender.

There is a TSB on a upgraded sender.

It can be done without pulling the transmission.

there is a D cut out on the engine head that the valve cover gasket can slip out of place in the D cut out

run your finger along the rear of the valve cover and you should be able to feel the gasket is not tilted out of place

there is a O - ring as you split the transmission / engine that is located above the crankshaft in the bellhousing cavity

 

It's the rear galley oil plug that's leaking now.
Just spent $$ fixing oil leaks from valve cover, oil filter housing, and transmission pan.
Only to discover this leak which now requires the transmission come out in order to access the rear galley plug.
In searching around I found out those were not torqued properly at the factory.
Should replace the rear main seal while I'm in there.
Also probably the driveshaft carrier bearing.
