Noticed a bit of oil on the garage floor. Got the car up and got underneath to inspect and cleaned.

Looks like it is coming from around the vacuum pump, which has been known to be an issue on other 5.0's (haven't found similar here). Examples here XFR XJ

I want to replace the seal. Have found PN C2D3771 but it doesn't list the XKR for compatibility as far as I can tell and have not been able to find a PN for our car. Looking for any suggestions.

Not driving much except to test, monitoring oil level as best I can.

 

They are the same vacuum pump as far as I know, usually just the seal is replaced, and there
are updated bolts as well, they stopped using the torx bolts and use metric standard bolts now.
