put a tee on your oil pressure gage run a line to an oil cooler capable of handling 100 psi or more in front of rad bore and tap a hole in the timing cover above the fuel pump for the return fitting hook up lines .that's how it's mostly done on marine engines which run much higher oil temps than any car will see .
I can't say I like this idea at all, unless there is some method used for flow restriction through the cooler. ANY oil flow to another route achieved by tapping off at this point will take flow away from the engine.
I can believe the part about the higher oil temps in marine apps.
