IMO, anything below 20 psi at hot idle is too low. I concur with the folks above to file a claim with Jasper now and follow their instructions.

Hopefully jasper will at least cover the labor difference for this one. Would be a bummer to pay for labor again and be without the car another 2 weeks.
Based on Jasper’s website, new oil pan comes with the long block. I know the oil pressure sensor is reused, but I replaced that with a GM sensor roughly 1 year/15k miles ago.
Cold idle was nearly 55psi today. Historically I change my oil every 5k on all my cars and run a blackstone every 20-25k or so.
Thats a really big difference to 10 psi hot...
I Think I'd at least report it to jasper....
And change the oil and filter... I once had a bad filter that was causing this issue
(on a different engine). It was a faulty filter.
Use an ACDelco or Wix filter. Do you use a magnetic drain plug ???
I do on all my cars and my customers' cars. It's a good indication if something
is really wrong.
The pressure sensor and/or sensor screen could also be an issue. they get
f'd up pretty quickly. Use a gm sensor if at all possible
Drove it into my ditch (not sure if enough) and added 2 quarts. Pressure went up a couple PSI.
Going to do the 500 mile oil/oil filter change with a AcDelco filter now and see if that changes anything.
If no change, picked up another GM oil pressure sensor just to rule that out.
Calling Jasper either way tomorrow morning

No it wouldn't at all. Just gives a bit more filter area and oil capacity
I use the Wix 57045 on all the gmt 900 trucks/suvs... It's a better, longer filter
than the wix 57060 that the 'book' calls for .. Kinda like the diff between the 48 to 63

Mine was higher but acting like that before changing the o-ring. Oil pressure is normal at speed but low (for my liking) at idle or low rpms.
With two mechanical oil pressure sensors you can determine about where the bleed down is happening.

What are the two locations for testing oil pressure? Jasper said “obd2 scanner is inaccurate”. Took it to the shop and they removed the existing pressure sensor to hook up mechanical gauge so not possible to differentiate what the root cause is and let it cool down to be able to even work on it and said “it’s 26psi”.
They swapped in a new GM oil pressure sensor claiming that was the issue. I may purchase my own M16 to 1/8NPT tee and do my own testing cause I feel this cannot be that difficult.
