Welcome back! I’m pretty sure I have enough Rx taken daily to assign chess board pieces to all the shapes, sizes and colors of the pills.

Well that didn't take long. Recovering from surgery and caught the flu. Now recovering from that.
Oddities:
Last week we were heading over to my father's home for his birthday. The truck was remote started and as I pulled out onto my street the Service Park Assist message came up on the DIC and the light on the button/switch would flicker. I would engage the cruise control and it would cut out every time the park assist would flicker. There was no problem on the way home and it hasn't acted up again since.
Was taking my wife to dinner the other night and while on the highway I noticed that the engine's oil pressure was about 10 psi below normal. The needle is usually just below 40 psi at speed and it was around 30 psi. Oil level was a little low but still showing on the has marks on the stick. My wife has been driving it mostly since I've been sick. We're about 3,000 miles on this oil change.
The next morning at the cabin I put they key in the ignition and fired it up and the motor didn't want to run. It stayed running at about 250 rpms, oil pressure was slow to come up and I shut it off and started over. Ran fine after that. Oil pressure was still low but not as low as the day before on the way home.
Idle pressure appears to be about 3-5 psi lower than normal, about 20 hot.
The first thing I'm going to do today with it is change the oil filter. I normally run the long K&N Gold HP2011 filters and it has an ACDelco PF48 on it right now.
If that doesn't rectify the oil pressure, I'll pull the intake and remove the screen under the oil pressure sensor. My 6.2s don't have them. She's still rockin' her original oil pressure sensor.
Comments, suggestions?

Scanned the computer system with the Tech-2 and P0521 00 came up, the oil pressure sensor! So in light of that revelation, we'll change that first and take it from there.
Good time to clean the throttle body and Mass Airflow Sensor too.

Last night we took off the intake and replaced the oil pressure sensor. Earlier, I had taken out the MAF and throttle body and did my annual cleaning, albeit a couple months late. Throttle body had some oil in it from the PCV system.
The rat chewed off some foam from around the air cleaner and moved it to the top of the back of the intake manifold. Guess he was going to set up shop back there, not anymore. He was spotted later in the evening so I guess he wasn't on that ride to Tampa a few weeks ago!
Underside of the truck is covered in oil. VLOM bolts were slightly loose. There was no screen under the oil pressure sensor, I was going to remove it anyway.
Oil pressure was still low, 19-20 psi in gear at idle. Torque Pro app could not detect historical DTCs.
This afternoon I took the Tech-2 and cleared the oil pressure code. Recycled the key and turned the motor back on, oil pressure still low.
After dinner my daughter and I put the truck up on the ramps and she swapped out the PF48 for the HP2011, motor was down about a quart so I topped it off once off the ramps and warmed up.
Oil pressure back to normal!
Since the rat has been eating all the toads in front of the house, I put out a trap with some pot roast on it!

Glad to hear the oil pressure went back up, I bet that was a relief! Good work as always, James!

Oil Pressure no longer normal!
There is oil everywhere underneath the truck and it is pooling on the ground now. The oil pressure is low again, holding at about 20 psi while in gear at idle and only going up to about 30 psi at speed like before.
So when it stops raining, will top off the oil and check the pressure again, then call a guy and see when I can the truck up on his lift and have a look around underneath.
What kind of external engine oil leak can cause the oil pressure to drop? Enquiring minds want to know!

A hole in the block? Oil leak into ezhaust emissions? The oil pressure has to escape somewhere.....?
Poor connection with the oil pressure sensor? Adjust your reading glasses ??
I know... I'm not helping.....
