I have a leak just below the filter on my 96 XJ6 VDP. I think it’s either a part of the oil pump or cooler housing.
I tightened the nut and it slowed the flow but, I know it needs to be re-sealed. Do any of you know if it is a gasket of simply uses RTV sealer?
Thanks for your time to reply.
In your picture I can see a little bit of oil on bottom of the filter, is that tight??
As for the fitting below for the cooler, or where the cooler would go, there are 2 o-rings. I had the same problem with my XJ40, you could use RTV if you have some laying around

You have a good eye. I saw that too and gave it an added twist ( was not tight) then tightened the mounting bolt for.the cooler. Cooler bypass still drips 3x a minute under pressure. I’ll attack it and a few other deferred maintenance items in a day or so. Thanks for the input! Also thanks to Parker for the link.
When I worked at the Jaguar dealer the other mechanics used to call the 4 oil cooler bypass 'O'rings 'bob-rings' because I replaced so many to stop the AJ16 oil leaks.
I also did this fix for my XJS. I bought aftermarket viton o-rings. I don't know what the rubber in the CAC5118 kit is made up of. I ordered it from McMaster Carr. Lemme know if you want details.
If you bolt the oil filter housing DIRECTLY to the crankcase, you can eliminate the oil cooler housing and the bypass assy.
You can just replace the 'O'rings and go on with your life.
Its a super simple job, and you only loose about 1dl of oil when pulling the bypass, so no need to wait for the next oil change to do it.
I would recommend having a sharp knife ready to cut the old o-rings though, as they are often hard like plastic due to age.

Your choice.
I’m a little dim this morning so bare with me... I get the idea of eliminating the bypass and directly bolting the filter housing to the block but what O-rings would I replace if throwing the bypass assembly in the dumpster?? Thanks for your patience.

you take the 4 bolts out holding the bypass and oil cooler plate, discard and throw in dumpster. then you get shorter bolts
this is an alternative to just replacing the o-rings on the horseshoe.
