It took me a long time to track down this oil leak, because I was blind to what was right in front of me.

I cleaned the engine well, put dye in the oil, and yet still couldn't figure out where it was coming from.
The engine block and head were dry (driver's side) above the A/C Compressor bracket, but under the bracket the block was soaked with oil.
The only things that seemed to be there were the left motor mount arm, and the oil pan gasket. I had decided that it was the oil pan gasket, gotten mad, and walked away.

Luckily, the next morning I looked at it again..and realized that the damn oil filter hangs off of the side of the left motor mount arm - and that the motor mount arm was the path for oil getting to the oil filter! DOH.. that explains that!

Well, next problem- do some reading, and find that the seal in question (Ford P/N XW4Z6840BA) is no longer available from Ford. However image searches on the internet / ebay for the mount arm make it appear that the seal is a simple (relatively large) O ring...

Luckily, further checking the Jaguar parts catalog, Jag still carries the seal for the S-Type.

In addition to that, one site has a couple of notes on the parts dimensions, (thanks to http://www.brit-car.co.uk)
Main O ring seal
XR816242 - 6.6cm x 6.6cm x 0.1cm (up to vin)
XR824893 - 7.5cm x 6.3cm x 0.3cm (after vin)

I've ordered both of these, as the oil filter housing hasn't changed- in the parts catalogue (AJ85632). I'm interested in seeing the difference (if one is updated/better), and will provide measurements for all of the o rings. It is possible that the block fitting changed between the years, i didnt' have a good way to check that.

The bolt also has an O ring in the jag parts diagram that I don't see in the ford diagram, and after disassembly I can see it is very important:
XR85180 - 3cm x 3cm x 0.3cm

I'm going to follow most of the Left Motor Mount replacement process to get into this piece, since i've done that before. This requires loosening the front sub frame, which sounds harder than it really is.

I'm not going to list every step. like setting emergency brake, loosening lugs before picking up car, etc. Anyway..

You can find the process, pics as well as this description here:
