Anyone recognise this Jaguar part?
Discussion
I think I may have a problem with the pressure relief valve but not sure from which model... Can anyone identify this please?
It's in my hot rod Austin which was built back in the seventies on MkX running gear with a few E-Type bits. It has since had some XJ bits fitted and I'm currently fitting a fettled 2.8 XJ6 engine. I can't use the later XJ6 filter as it doesn't clear the chassis rails.

It certainly does - I'd previously looked up images of Mk2 filters and got different results to that... it's surprising how many different styles were used between models. Until I started my rebuild I was under the misapprehension that all these bits could be interchanged at will between the various models (Mk2/420/MkX/E-Type), to a certain extent they can but caution must be taken...
I guess most of the engine bays were a little tight for space, so things had to be fitted in where ever they'd go.
I had a similar situation when getting triple carb manifold for my XK150. On a RHD car you need a Mk10's manifold not an E-Types one.
The E-Type had a top clearance problem so the manifold swan necks down to let the bonnet line be lower. But on a RHD 150 that means it fouls the steering column.
You mentioned that one of the oil filters you'd looked at fouled you chassis frame.
I guess this happened to Jaguar too.

It's from a 3.4/3.8 MK2, Stype. The oil pressure relief valve is below the oil return outlet that connects back into the sump; i.e. the hex headed pipe pointing downwards in your pic. Unscrew it and you will find the relief valve and spring under it. The valve frequently coggles slightly in it's seat. The trick is to make a small saw draft in the head of it so you can reface it to the seat with valve grinding paste using a screwdriver. Refit it with a new spring and it should restore your oil pressure back to new, providing everything else is OK!!It's in my hot rod Austin which was built back in the seventies on MkX running gear with a few E-Type bits.

Thanks Jith, I thought I'd just buy a couple of new bits for it but they seem harder to come by than I thought... already had it apart and cleaned it, and tried preloading the spring with a couple of washers to no avail so will try what you suggest. I'll keep fingers crossed that reseating this and renewing the seals in the oil pump does the job... be nice to have oil pressure on my new bottom end!
