6.0L weird oil pressure problem
Bad news,
during street tuning, the first WOT pull i made i noticed as i cam to a stop idle oil pressure is now 20psi ..... again im going to have to verify this with a mechanical gauge other that that also should probably install a new sending unit. ill keep it updated any input is appreciated

Verdad Gallardo got a mechanical gauge on the way. Couple of guys at work who also know these motors well thinks it's the cam retainer plate since i did replace it and they can sometimes blow out if under torqued
I've also been driving it around with the **** it mentality and it honestly runs very well very quiet no ticks not putting the bearing failure past me yet.

After all of that... This all sounds like a classic case of worn bearings.
Not worn out yet... But on there way to be.
Time to disassemble and get a look at the main journal bearings to start.
If you ate lucky, you may be able to just remove the engine oil pan and replace the main journal bearings one main cap at a time while under the vehicle.
I hope I am wrong... I wish you good luck!

Put a mechanical gauge on it..... the gauge on the dash is 8-10 psi off so I have 30psi at idle when the gauge shows 21 ish I also logged oil pressure doing some driving around it is steady 30 at idle. 65 at 6k rpm
when it warms up I'm going to check the Oring I'm willing to bet I pinched it.

Where on the engine are you measuring the oil pressure?
These engine can see a significant difference in oil pressure, depending on which oil pressure port was selected to connect to the mechanical gauge...
The factory oiling system will route oil through the camshaft journals down to the main bearing journals.
Therefore if oil pressure is measured only at the valley cover for example, lower oil pressure from the main journal bearings back towards the camshaft and lifter galleys may not be detected (due to worn main bearings) in comparison to oil pressure between the pump and the driver side lifter galley...
Take a measurement at the driver side cylinder block location right at the turn out of the oil pump into the side of the cylinder block. Compare both locations oil pressures.
Should there be significantly less oil pressure at the valley cover location, than there is excessive ware in the main bearings and/ or possibly rod bearings.
Sounds relatively fine... With in spec. anyway.

should be noted 30psi was the hot idle it's 45 cold as it comes up to temp I was seeing 30psi even after hard runs. This is with Mobil 1 5w30 full syn
