    Idle Oil Pressure Thoughts (Currently sitting at 20 PSI fully warm).

    GM replaced the engine under extended warranty, so they only replaced the bare minimum which was block non-reusable parts and gaskets unfortunately.

    Idle Oil Pressure Thoughts (Currently sitting at 20 PSI fully warm).

    Running AC Delco Full Synthetic and the UPF48R per the TSB to increase oil pressure. My larger concern is that 15k miles ago it was sitting higher at hot idle and when I was looking over the receipts from when GM replaced the engine block it seems like they reused the same exact oil pump which...

    Idle Oil Pressure Thoughts (Currently sitting at 20 PSI fully warm).

    My main concern is that I'm showing 45 PSI at the oil filter and 20 PSI at the top end when fully warmed up. The Dealer technician's note that this is lower than what they usually especially after a recent oil change. I'm thinking of giving this a chance before replacing the oil pump as I'm...

    Idle Oil Pressure Thoughts (Currently sitting at 20 PSI fully warm).

    Hey all, Just got back from my Chevrolet dealer who told me everything is within specifications for my 2008 Avalanche 6.0L. While the compression test came back perfect the Oil Gauge test showed something interesting. At the filter I'm getting 45 PSI at idle but by the time it reaches the top...

    Looking for a Tune (Disable AFM and Raise Idle) near Philly

    Hey all, Does anyone have a recommendation for somewhere that can do a ECM Program / Tune (Disable AFM and Raise Idle) near Philly? I've spoken to 3 shops, and all are quoting the same cost as me buying a Diablo Tuner myself.

    Yes I can take a photo tomorrow. The box contains ground as well so I just used spade connectors

    Heated Steering wheel upgrade for 2010 GMC Yukon XL

    When I upgraded my 2008 Avalanche to include a heated steering while I bought the wiring harness as well and it turned out to be useless as there's a missing pin in the next portion of the harness. I wired the green heated steering wheel into the accessory box to be on iginition and haven't had...

    Mysterious (to me) fluid leak driver side

    The fluid is corrosive as well for comedic value.

    Broken Motor Mounts

    Keeping an eye out! I can say it has gotten worse since I originally noticed it when it was once every 4-5 seconds. Now we're in a pretty constant state of stumble / occasionally it feels like it's sputtering if I put it in gear before it's fully warmed up. Also, the truck seems less able to...

    Broken Motor Mounts

    Haha not yet. I’m used to our normal vibes but these ones seem to be getting a little worse as time goes on. The upside is that all the things I’ve done on the truck have definitely improved the overall “feel”.

    Broken Motor Mounts

    Finished the passenger mount yesterday. I've done a lot of jobs on cars and the angles on this one are comical. Turns out my starter posts were rusted out, so it turned in to quite an adventure when it broke in my hands on reinstallation.

    Uneven Idle is getting progressively worse but cannot find the cause (Fuel Pump / Injectors?)

    Well it wasn’t the pickup tube O ring or the passenger motor mount. This might be the most frustrating mystery of all time.

    Hummer H3 5.3 engine mount - online vendor?

    Less common but they're made of rubber and are 8 years old in your case.

    Uneven Idle is getting progressively worse but cannot find the cause (Fuel Pump / Injectors?)

    Quick update. Replaced Oil Pickup Tube O-Ring / replaced the leaking Oil Cooler block and that helped oil pressure a hair, but the idle issue is still there. I know the Passenger Side Motor Mount is bad so I'm going to tackle that next but I'm at an absolute loss at this point.

    Uneven Idle is getting progressively worse but cannot find the cause (Fuel Pump / Injectors?)

    Checked both sides of lifters and they’re all moving correctly / the engine has 35k miles as the first one died of lifter failure.

    Uneven Idle is getting progressively worse but cannot find the cause (Fuel Pump / Injectors?)

    Removed / cleaned / tested all 8 fuel injectors / replaced the O Rings and there's 0 change. I'm at a loss for what else it can be but the idle is terrible.

    RESOLVED - Stripped out the cylinder head bolt hole while replacing valve cover, what now?

    Are you using a ratchet reducer?

    I will check them! I replaced all 4 O2 sensors 10 or so months ago.
