    PF48E - 12710960, how is it?

    Looking to do an oil change after 3k and thinking of trying out oem filter this time. Previously put FRAM TG10060, it’s much larger than the PF48E I received. Wanted to test if pressure changes with smaller oem filter. Attaching pic of the one I received. Was wondering if anyone has ran a...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Replaced fart suppressor today, ordered from TheSeatShop. Night and day! You can see old one on driver left was completely soft and squished. The softness change feels more than when i changed struts, amazing.

    5W-30 vs 10W-30

    Looking to do another oil change soon on my 08 Yukon 6.2 with 135k on the clock. Was thinking to run an engine flush before the oil change, put a PF48 ACDelco filter but unsure about which oil to get. I've looked around the forum and some folks stick with 5W, while others lean towards 10W on...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Update after a week with predator 93 tune and raising idle/parl rpms - i can’t believe how much smoother the car drives, not a single vibration when idling, takes off super smooth and rough shifts are gone. Think I’m going to add tuner to my must have/do list on any older used car in future.

    Lmao, in Canada it says “Construction zone, road workers present”, Michigan doesnt **** around and simply puts signs with “Kill a worker - 7500$ fine and 15yrs in jail” Still unsure whether it’s giving me a warning, challenge or just straight up a price tag.

    Diablosport tuner t1000

    Did you increase idle rpm with it? I was about to post that question! I’m looking to raise idle rpm a little, mine are at 500, the truck does NOT like it. If a 80$ tuner will do it vs 700$ black bear, ill go down that route

    ‘07 Denali XL, should I invest?

    Bought similar one in September as something id like to learn on while doing majority of repairs myself, have a 2nd car being brand new to make sure I’m never stranded. However the 6.2, comfort and size of XL Denali is so superb to even new cars that i just can’t stop driving it as my daily and...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

So i went ahead and changed: - New valley cover - New oil pressure sensor - Valve cover gaskets ( i was...

    Oil pressure 40cold/20-25hot, safe to drive?

    Update: put everything back together, let’s see if oil leak stops. Hot idle didn’t change, however cold and hot driving is now slightly higher. Think ill consider it “acceptable” based on other posts here and tackle oil pan with pickup tube in the summer, when boat is out of garage:) New...

    Oil pressure 40cold/20-25hot, safe to drive?

    I see! Weird because Dorman part pic had screen on it, but came without screen today lol. Cleaned around a little, installed new valley cover, sensor and passenger side valve cover gasket with grommets. Wife won’t let me finish other side with “are you done yet?”, so finishing driver side valve...

    Oil pressure 40cold/20-25hot, safe to drive?

    While waiting for oil pressure sensor i took old cover off and cleaned everything. Turns out old sensor had no filter/screen inside, is it missing or some engines didn’t have one??

    Oil pressure 40cold/20-25hot, safe to drive?

    Yep, 3 bolts on it were completely loose, others not tight either, so oil was spitting out under pressure. When i mean completely loose i mean like completely, take one finger and unscrew it

    Oil pressure 40cold/20-25hot, safe to drive?

    Replacing valley cover, pressure sensor and valve cover gaskets today-tomorrow, waiting for final parts today. 3 bolts on valley cover were finger-loose, didnt have to put any effort to unscrewing them, they just moved completely freely. Got the idea to check them thanks to this great forum...

    Oil pressure 40cold/20-25hot, safe to drive?

    Gotcha, thanks! It’s about 20-25 when idling or cruising at 1000rpm when fully hot, going all the way to 40-50 when i hit the gas

    I think it’s been same since i got in September, didn’t pay much attention until i saw posts recently where folks had seal issue with similar pressure

    Oil pressure 40cold/20-25hot, safe to drive?

    Hey folks! Noticed i have lower than ideal oil pressure when yukon warms up. Pickup tube seal most likely. There is also small oil leak from the oil pan that i was going to tackle somewhere around April when it warms up and would be replacing pickup tube seal as well. Wondering if it’s safe...
