Oil cooler pressure

[dsmtalontsi95]

So I have a 90 oil cooler and was wondering what kind of pressure the cooler see's? I'm not sure it would see full presure as I would think it would be on the return side of the filter housing (No more then 40 psi I think). I can't find an answer on the forum. Any one know what it would be?

It should see close to engine oil pressure, whatever that may be for your engine. There isn't really a "return" to the oiling system. The oil is fed to bearings, cams, filter, cooler, etc. and "returns" by draining back into the oil pan through clearances in bearings and oil drain galleys cast into the block/head.
