When my truck heats up, my idle oil pressure drops to about 30 or so, and the WOT 6300 RPM oil pressure is about 50 psi. Should I be concerned about this?

 

I dont think so, mine was at 35lbs today in 97* heat at idle (800rpm) It goes up to 50lbs under throttle too.

 

That seems a bit low, but then again I have high oil pressure. My lq4 has about 50 at idle, 70 under part throttle, im sure it will hit 80 under wot, just havent brought it up that high yet. Need to get tuned first.

 

My 5.3 was about the same as your LQ4.
