I meant no ill effects. Pegs the gauge cold and about 60-65psi at 2k hot. Running hx bearings also
Low Oil Pressure?

Good to know.
Realistically, can the oil even get hot enough to loose noticeable oil pressure because of it thinning?

between normal driving and light towing over the pass last weekend with a completely unideal setup, ie. big turbos, filled block, etc i didnt see oil pressure dropping lower at 65 or idle honestly.
Yes.
Before I did my oil cooler and I was cheaking my oil temps I took a trip over parleys with the boat on a hot day and held speed and rpms as consistant as I could from the bottom to the top.
My oil temp went from 225 to 283 and my oil psi dropped from 38 to 25.
But what about on a truck that never tows, and it happens just highway driving?

Try some Schaffer's 5w-50,it's amazing stuff. I've always had kind of low oil pressure, I'm pretty sure I need to replace my oil cooler.
I'm waiting for the engine builder to get back from vacation to get the specs. I do know it has very loose clearances though.

Update. Motor is back together, this time with a melling pump. Oil is where it should be stock, going to try a different weight oil next oil change and see how much it improves. This motors twin did the same and picked up much better pressure.

That Lucas oil stabilizer works pretty well. Mine stays above 30 psi now. Before I was getting into the 20s at wot

I ran Rotella 15w40 once in my stock motor and could immediately tell a difference and lower oil pressure. it also burnt some in 3K miles where as I have never had to add any with Delo 400 15w40.
I just built my motor. New oem pump is at 19-20 idling with engine temp at 190. That's with 15-40 delvac My mains are just a hair over .002. Not sure if the oil holes in rods matter or not. But like stated above. Main clearences have a lot to do with it.
IIRC, 14 psi @ idle is factory min spec. Oil pressure that's too high isn't always good either....
