  1. What's the oil pressure at highway speeds? I suspect worn lifter bores bleeding off pressure from wear incurred due to extended oil change intervals (following the GM Oil Life Monitor) Been down this road with my fiance's 2013; 120,000 miles. Had lifters done due to lifter chirp and then 6 months later I stomped on it to pass on a two lane road and spun a rod bearing. After the lifter repair oil pressure was lucky to be 25 or 30 running down the interstate. If I had it do do over again, I'd have run Rotella T6 5w-40 or even a 20w-50 to keep the pressure up; It might have saved, or at least prolonged the life of the motor a little bit.
  2. I had my pressure washer roll forward and take out mine about a month ago. Covered under comprehensive insurance, so it shouldn't effect rates the way a collision claim would. Bill with OE GM glass and install was $1,350. Insurance covered it less the $100 glass deductible. Call your agent. Worst part was waiting the 2 weeks for the dealer to get the glass in.
  3. Nothing wrong with it. Drive it till it's paid off, then enjoy payment free driving for at least a little while.
  4. Maybe shower after your workout. Otherwise, some good seat covers you can wash the funk out of.
  5. Sounds about right for e-rated tires and 3.73 gears. The gears will kill your hwy mpg. My old 2008 GMT900 with a 4 speed and 3.73 gears never did better than 18 on the highway and that was with a tune and 93 octane fuel on P rated Michelins. I towed my 3k lb boat/trailer combo 400 miles over labor day weekend and i think the computer said 13.5 when i got back home, which means somewhere between 11 and 12.
  6. 2018 5.3 8-Speed 3.42 87 Octane If I hand calculate it, it almost always comes out about 2mpg less than the computer. My 87 mile commute north to Tennessee every weekend has a lot to do with this. Google maps shows that trip almost always comes out to an average speed of about 50 mph. I normally get 22 to 23 on the interstate with the cruise set at 72mph. Around town, in my small city with lots of red lights and a heavy foot, I get between 11 and 13mpg.
  7. Well, I'll see you on the other side.
  8. This... possibly. The viscous coupling in an engine driven fan typically fails in the locked up position. With the truck in park and warmed up, rev the engine and listen for a howling noise from the fan.
  9. The OE AcDelco wires lasted you 8 years. I think (actually, I KNOW) ACDelco is what i would replace them with. Monkying around with aftermarket plugs and wires on these trucks seldom ends well.
  10. Weathertech floor liners and a toolbox. Not much need for pictures here.
  11. Likely looking for help on the $50k retainer that Dewey Cheatham & Howe asked him for.
  12. With that much salt, you need to be lubing the sliders and pins on the calipers every spring. Its pretty plain to see what happened. The pad backers corroded and stuck on the slider. causing the inside pad to wear prematurely. It's not uncommon on GMT900 and K2 trucks to go 100k miles on a set of OE pads/rotors.
  13. Young and dumb. Camera phones were a bit more primitive in 200404
  14. See Pg 17. https://www.gmc.com/content/dam/gmc/na/us/english/index/about/trailering-towing/02-pdfs/GMTB18CT100-2018-gmc-trailering-guide.PDF Best reference I could come up with on short notice. I can assure you, my window sticker says 3.42. EDIT: Looks like the 6.2 8-speed non-NHT trucks only came with the 3.23, but the 5.3 were available with 3.08 or 3.42
  15. Congrats. I own its fraternal twin. SLT PP 5.3, 8Spd, 3.42 in red quartz tintcoat. Only difference is the wheels. Bought last April for $13k off the $57k sticker. Love the truck unconditionally.
