Bearing problem?
7000 miles is way too much on a dod/afm engine with vvt... Oil cleanliness and pressure is Everything!!!! It's def bearing material if it's like tiny sparkles If it still runs fine, keep the oil changed way more often.. Install a magnetic tip drain plug (won't catch non mag metals of course)- Foggy

Oil Pressure - Am I paranoid?
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- Foggy

Oil Pressure - Am I paranoid?
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 ...- Foggy

P0171 & P0174, Fuel Pump?
Usually those codes are vacuum leak oriented 40 psi is lower than it should be.. does it stay at 40 \??? or go back up some when you let up some on the throttle?? And how are you monitoring the fuel pressure ?- Foggy

just changed my plugs....
To add: you have the earliest GMT900 and many had oil ring issues. I see you've made another post... Try to keep it all in 1 post so we can help better. They also had some piston slap issues. May be time for an engine pull to replace bearings, rings, pistons You'll have to decide the value...- Foggy

just changed my plugs....
An exhaust leak will cause your oxygen sensors to be off which would really mess with fuel trims. Almost 20 years old, anything of course is possible. I would get the exhaust leak fixed, do the basic maint like plugs, wires, clean maf, clean TB, etc .. Then clear all the codes and reset...- Foggy

just changed my plugs....
Those TR55 plugs are very common in the LS world. TR6 is more common: it's the same plug just gapped diff at the factory They should have been pre gapped from the factory, but you never know what gets thru these days. Make sure to just replace them with real NGK or ACDelco plugs per the...- Foggy

2008 2500 Suburban
6 speeds are good. Weak point is the torque converter. If trans shifts good and fluid looks really good you could just have the converter replaced with a good aftermarket unit and then have some HPTuner work to really get it shifting right and make changes for longevity ... If it's not in...- Foggy

Replaced afm lifters
Random P0300 misfires could also be: fake spark plugs and/or wires make sure to get them from a reliable source : NOT Amazon is what this means. Fake parts are everywhere. Your local parts store will be more expensive than mail order, but will be the actual parts. Use AC Delco plugs...- Foggy

Best Brake upgrades
I really like my powerstop truck & tow rotors/pads kit. They are stock size so no mods necessary. They bite really well and last a long time. Slotted & drilled rotors with tow pads... I could really tell a huge difference from stock for sure- Foggy
