Tried to figure out my oil pressure issues. After the engine heats up the pressure drops. Changed the filter and oil. It looks like glitter in the oil.Instead of taking the motor back apart to change the bearings i put 50w oil in it so it will hold pressure long enough to trade it in.
Oil pressure will drop after warmup, How much of a drop are we talking?
0-5lbs. kill the truck for a minute and the pressure goes back to normal for a minute or two the drops to barely 5lbs. With the thick oil the truck holds pressure for about 20 minutes after the truck gets hot.

Good luck man
