So, is the plan to have 2 sandwich adaptors at the filters, each running to a separate cooler?
you just don't want your oil running too cool.
Ant, Tinus's concept is to replace the existing filter housing on the engine block with one which doesn't have the existing inter-cooler built in, but which does have ports built in to feed and return oil to and from a cooler or multiple coolers.
I have a few concerns, but I don't like the idea of double sandwhich adapters much either. And that standard oil/water intercooler is a known weak point on the TD42.
My primary concern is that I suspect it will take significantly longer to get the oil up to a reasonable working temperature. Whether or not that is a concern depends to a great extent how the car is used.

iam going to give mr Connan a oil cooler and then we are going to see what can work without after market adaptors but please give me your plans and findings
Ant, Tinus's concept is to replace the existing filter housing with one which doesn't have provision for the existing water/oil cooler in the side of the block, but which has feed and return points built-in.
I have a concern which I have already discussed with Tinus, which is that I believe it will take considerably longer to heat the oil to operating temperature, but whether or not this is really an issue will depend to some extent on how the car is used.
On the other hand, it does have several possible advantages including eliminating the possibility of the oil/water cooler rusting through (which is a known issue) and having far fewer connections that need to be leak-proofed. It will also mean that there is enough space to run the bigger filter which one may lose when fitting sandwhich adapters.
I would think that with a multigrade oil like most of us use the acceptable window would be considerably wider than that?
For example, I know that on the Spitfire you have to wait for the oil to reach 30 degrees C before you run up the engine to check power and magnetos. I suspect this is lower than ideal because the plane also has a tendency to overheat on the ground. But by that temperature the oil must slready be delivering fair protection or they would make the temps higher. For interest's sake, the water temp needs to be over 60.
I also suspect that in a non-regulated system like that (no thermostat) you have no chance of keeping the temps within such a narrow band.
The added quantity of oil through the pipes and the cooler you do not need a lot of cooling. If you mount it behind the fog - lights on the bumper, you should have ample cooling.
