So where do people plumb their oil cooler? Seen arguments for the various positions.

Currently getting too much over cooling, so fitting a canton thermostat. Engine is dry sumped.

Oil cooler is currently fitted on the return to the tank, but figure I'll get more heat on the feed.

If it's getting over cooling in its current location then I don't see any incentive to try to optimise the layout to improve cooling.
Well the idea is to reduce thermostat opening on the feed. Oil on the return will be warmer and open the stat sooner right?

Or will deaerated oil cool more on the feed line?

coolers are most offten on the return to prevent heat build up in the tank. If you have too much cooling then as said either use rad blanking or a thermostat,
Or is the cooler too big?
In racing we look for around 110-120 deg, although alot of modern oils are happy at higher temps now.
Eitherway you want it to get over 100 regularly to remove moisture
I've gone for the canton stat as it's straight through when closed with minimal restriction and opens at 215 degrees F. Tank is in the front, but the oil cooler is actually quite large and difficult to block off but has been running successfully for a few years by the previous owner, I assume in warmer weather.

I'll put it in the return as before.

That temp sounds about right.
reminds me of my first time engineering a car in the us, the brake guy handed me a slip of paper with the brake temps on after a pit stop, i shxt a brick, as the temps were in the thousands, bloody gave it to me in f not c.
That's the thermostat opening temp.

Oil temps are 60 degrees with the current setup.

I'm also fitting a Peterson remote oil filter with priming pump, saves removing the plugs and priming it when the oil drains to the sump.

Well my opening post did say it was overcooling, that's why I'm buying the thermostat. 60 is far too low.

215F = 101 Celsius. Most seem to open at 80 which seems low and have small openings. This thermostat is pretty big.
