  1. I had a 99 GMC Sierra classic which was the old body style, sold it 12 years ago. Another way to tell between the two is the old body style came with the 5.7 and the new came with 5.3s.
  2. Not an expert but The K in front of the number used to mean 4 wheel drive. Another thing to keep in mind is1999 was a transition year for the new GMT 800 platform as well as still producing the prior GMT 400. So there were Two body styles in 99. Hope that helps.
  3. I have been running Mobile 1 oil and filter on my 08 since almost new. My oil pressures are exactly same as yours.
  4. On my 2008 Sierra when I removed the OnStar module and drove the truck it threw codes, Service four wheel drive, ABS light and engine light. When I reinstalled it the codes reset and went away. Not sure if there's a work around with tech2, but I kind doubt it. Maybe you can try relocating it?
  5. Doug, Are the interior colors on your truck Dark Slate/Walnut? I prefer that to the Jet Black. It goes very well with your exterior color on your truck! Cheers Dennis
  6. The X31 package is $850 for the Sierra which includes Hill descent control, Skid Plates, High Capacity Air filter and X31 badging, wonder what the badging is? Also included 2 speed transfer, p265/65 15 All terrain tires and Dual exhaust!... Interesting
  7. I will be curious to see if the K47 High Capacity Air Filter will be interchangeable with the standard filter as in years prior, or if the air box is different now on the 19s. Looks like the only way to get the K47 option is with the X31 off-road or VYU Snow Plow Prep package.
  8. I went with AC Delco Durastop when I had the rear drums done, I think they were like $65 at Rock Auto.
  9. Our year trucks do not use a PCV valve, not sure what year they began omitting them. The revised valve cover has a baffle in it to prevent it from sucking oil.
  10. My 2008 5.3 had been using about a half quart every 3000 miles. Since it wasn't leaking or burning any oil I targeted the AFM by doing two things, I installed a updated drivers side valve cover and had the AFM turned off in my Black Bear Performance tune. It now uses zero oil. I cant say if it was the valve cover or AFM or combination of the two that was causing the usage.
  11. Your options are to disable AFM and to leave it in 8 cylinder mod with the range unit mentioned above or a custom tune. If your talking about wanting delete it entirely the kit with all the hardware starts about $400 and involves tearing down the top end of the engine.
  12. Bought a GMPP cold air intake #17800809 for my 08 Sierra years ago, ran it for a few weeks and got tired of the intake noise, removed it and put the stock air box back on. I would like to sell it, Its been sitting in the garage ever since just taking up room. what do you guys thinks its worth?
  13. +1 for Rockauto. I just ordered rear shoes from them for my 08. One thing you will have to decide on is which ACDelco line you want, they have three grades, Advantage, Durastop and OE.
  14. when I checked the shoes at 79k there was about 1/16 of an inch left, I'm now at almost 90k, what would that equate to how much is left before replacement? I don't plan to do the brakes myself, I got a bid of $250 just for the ac delco shoes and found them online for at least half that, thought I'd save some money and get the parts myself rather than pay full msrp.
