Oil coolers

Mike, you live in a different universe than I, apparently... Most
everything you say here violates what I know to be engineering fact, and
thermodynamic necessity, after a lifetime of building up and burning down
engines...

Oil absorbs internal heating of engine parts from both combustion and
friction and transfers it to the external metal of the engine (primarily but
not limited to; oil pan, rocker covers the big two, crankcase, and
propellor hub, and a cooler if present) and that metal then transfers the
heat both convectively and conductively to the external world...
Up to 40% of waste heat is transferred out of the engine by the oil
according to this source http://www.uccc.co.uk/when/hycwoil.htm
- actually that looks a bit high and I tend to size my calculations on a 33%
basis...

Engine cooling is a science, not guesswork, and there has been millions of
dollars spent on research since the invention of the internal combustion
engine as a prime mover... In ten minutes I could amass dozens more
authoritative references, but I suspect it will be wasted effort...
Have a good un...
