In my opinion and any car that is built or built to perform should have cooling a big factor.
I built the motor from top to bottom to be a beginner drift car. Just to practice and get the feel. and after awhile possibly upgrade to a better motor or different car.

Cool engine is not necessarily always a good thing. You gotta remember, cold thick oil is just as bad for your car as having low oil pressure. Oil needs to get up to roughly operating temp (60-70*) to efficiently lubricate. If it takes it so long to get to that point since you have an oil cooler, then you are hurting the engine.
My wife's 325i BMW gets the white milky residue under the oil filler cap too. I'm pretty sure its just condensation due to weather/temp changes and the car not being driven far enough.
As far as moisture under the cap, it probably is just condensation. But 148 psi across the cylinder seems really low for an NA engine. I know the KA24Es have slightly lower compression over the DEs but minimum acceptable compression for them is about 150 psi. I'd drop a capful of oil in those cylinder to see if the compression jumps. If it doesnt jump, then its probably your HG going out.
