2 full oil changes with wix filters
You can try and replace the oring and see if thats the issue, it is pretty easy to do. You could have an issue with a failing oil pump relief valve. It's good to see you have good pressure at startup.
You could do what I did, take the oil cooler return cover, located just above the oil filter, and make an aluminum test block off plate to stop oil from going through the engine. Drill a hole in the block off plate to line up with the forward hole. Tap the cover and put a manual oil pressure gauge in the hole. Start the engine and let it run for about 5 seconds while you monitor the oil pressure and then shut if off. I'd put the test plate in after the engine is hot/warm when the oil pressure has died. If you deadhead the oil and the pressure is still low then you have a pump or oring issue.

bad news pulled the oil pan and found gunk up oil and metal shavings . i also cut the filter and found the same so i think the 6.0 out and the 4.8 is going back in . do you think the 4.8 will have bad street manners with the tr 224 thats in the 6.0?oh with out a stall, that might have to be put on the back burner for a month or my bother can recover from the holiday expenses.
how much shavings?
