Military oil cooler on civilian engine

What modification are necessary to plumb a series military oil cooler into a 2495cc petrol engine?

I know there's a sandwich block on the filter, but how is the return routed?

Why would you need one? If i recall they were only fitted for keeping radio vehicles cool when they were running flat out for extended periods

To answer your question though, i can look on my dads lightweight but it won't be for a while

2.5 Petrol had an oil cooler when fitted in a Ninety or One Ten. His doesn't, because it is in a Series.
Personally, I doubt if it is needed for UK use. If I did want to fit one, I would probably used the rad out of a Ninety, which has one in it.

It's a high compression engine, and I'll be taking it to the desert.

It's going to a lightweight with an FFR oil cooler.

I would really appreciate that. Photos would be amazing, but a description would do.
Thanks.

Should be possible to connect the inlet and outlet on the oil filter adaptor to the FFR cooler.
But as I have no idea what the FFR cooler looks like, I don't know if you will need made to measure pipes.

I'm wondering if a TDI 200 sandwich block would make more sense, despite the return coming back on the wrong side of the engine.

Return from old style oil cooler went to a port added to sump.

Yes, I understand. Is there a thermostat in the old system, do you know?

Optional parts catalogue shows the parts and mentions a thermal bypass assembly.

That's useful, thanks. I think I need to see an installation to fully understand the layout.

Then I've to find the bits!

Thanks again.
