Hi
I am building a 1927 T bucket and my drive line is all 1974 s2 xj6. I am using the engine, automatic and rear end. Using all the gauges and as much of it as I can. The car was rusted out.
The one in your picture is out of a Mk2 Jaguar and others, I expect. They interchange amongst the six cylinder engines. You just need to select the correct gasket and we can help with that.
So from what I have been able to learn on this forum I need to check how many bolt holes it has etc to figure out what will fit etc. I’ll have a closer look this weekend.
I have a 3.8 (1962) and a 4.2 (1972) that both have the same XJ6 Series 3 filter head with the Series 3 spin on filter fitted. These project outward so won’t suit your application.
The point is adaptations are pretty forgiving.
4 bolt filter heads fit any block. The important thing for your purpose is to to avoid the early model mounts that had an internal bypass. Later mounts all had an external hose that dumped into the sump.
Do a search for @Wiggles Jee-Type conversion posts. I think he used the same XJ6 power.
I’m not familiar with the Mossman kit, but as Paul says; the series 3 filter is changed downwards - and is a direct fit on all xk engines. Getting an assembly off a wreckers is a good idea, and you will also get a look to see eventual problems related to your special requirements.
In the picture that you posted of the engine on the stand you can clearly see the by-pass hose mentioned by Mike. The 4.2 sump accommodates same - has to be external.
