    1999 GMC Yukon Denali 4x4

    You've got a GMT400, actually... Why are you asking that? Have you tried cranking it to see what happens? That may have been the first years of the BCM, IIRC. I recently parted out a GMT400 2000 K3500 OBS truck and those did not have a BCM. Your body style are the only GMT400 with a BCM.

    Oil Pressure - Am I paranoid?

    I think generally the human psychology wants to see "halfway mark" on the dummy guages. Otherwise we start wondering things... 12 psi at hot idle on a new crate engine does seem a bit low to me. We have a vehicle with the L96 6.0 and that one idles around 20 psi hot. It's got like 25K miles and...

    Cylinder head question

    There's no "break-in" procedure for the heads AFAIK... That's only for piston rings/cylinder bores after a rebuild (or a brand new engine build), but I don't even know if they even specify that on new vehicles anymore?

    Engine build/rebuild precision tools

    Thanks! Yeah, I'd never handled a nice set of dial indicators in my life until now. The fit and finish eeks quality. Oh, I did watch a video on the calibration of torque wrenches. Will try that, thanks! I understand the concept of torque very well (civil-structural engineer by profession, and...

    Engine build/rebuild precision tools

    I bought a 0-1" Mitutoyo digital micrometer ($130) and a Starrett 6" dial calipers ($150) from FBMP. The Starrett were still sealed in their box and the Mitutoyo practically brand new: Not too shabby...

    Lifter tray question

    You can definitely just replace the trays, yes. Lifters? Umm...probably need to inspect first. Same for the camshaft. Any wear, and both should be replaced. Are you doing the work yourself? If hiring, ask your mechanic for his opinion on tbe wear. On the Summit Racing camshafts, tbe...

    OR VietVet Is Still Throwing $$$ at 2005 Z71

    Nice! BORING oil changes are the best! I was contemplating ordering those filters, but placed an order of a dozen of the standard ones. Do the long ones hang below the oil pan? The biggest gripe with the standard ones is they sit within the oil pan recess, so my Channelock oil filter pliers...

    No A/C, driving me crazy.

    Is this the auto control HVAC? Have you tried that recalibration procedure? If so, have you checked that little ambient temperature probe on the driver's side headliner? It's got a little wheel and mine was seized and the temperature didn't work properly (I'm not sure if that will cause your...

    Need advice with ordering valves and cylinder head gasket

    Ok, I was afraid you were going to say that those engines are not common there... The valves are different size between the intake and exhaust. That's not what you are talking about, right? I saw on your other thread someone mentioned you have an LP conversion? I see Rockauato does show...

    What year is this vehicle/engine is this BTW? 2006 Escalade? LQ9?

    Engine build/rebuild precision tools

    I've rebuilt a few of these engines, without the need to do any major machine work (actually, none to the block). I started by buying a used Mitutoyo dial bore guage from eBay and a set of Summit Racing micrometers 1-6" range, and the mics worked okay. I was intimidated by the micrometer...

    Need advice with ordering valves and cylinder head gasket

    Umm, I'm not familiar with the heads portion on these engines, but have taken a few heads to my local machine shop for reconditioning. I once took them some heads from a LQ9 engine I'd bought but had spun a main bearing and catastrophic damage. Those heads the machine shop told me were already...

    2013 Denali with 6.2 prone to burn oil?

    Shouldn't be burning oil at that mileage, no. If you are bored and want to kill time, you can do a compression test, but I wouldn't bother. If you suspect some negligence from the previous owner, run some Valvoline Restore & Protect. I haven't used it myself, but there's several guy here that...
