    Melling M561

    Pump showed up. To an untrained eye, it looks pretty nice. Not a big fan of phillips-head screws. They were hand-of-God tight, had to use an impact screwdriver to break them loose. No threadlocker or lubrication on the threads, so just torqued like mad. Will probably just put them back in...

    Melling M561

    I prefer gerotor pumps too, so I might also order one and try it out. Going to be a nearly stock rebuild (LBZ rods, race cast pistons, SAC45 injectors) but a better oil pump can't hurt. Sent from my FlashScan V2 using Tapatalk

    Melling M561

    I'm rebuilding the LB7 in my utility bed, and need to replace the oil pump. It looks like about 6 months ago Melling released the M561 as an upgrade to the M316. From what I can see it switches from the stock spur gear design to a gerotor. Has anyone tried one of these? Can't find much...

    LB7 - Engine starts then dies - Reusing low pressure fuel hose clamps

    That's the official name the service manual calls it, but I have no idea why. Sent from my FlashScan V2 using Tapatalk

    No start issue.

    That does pretty clearly seem like a mechanical issue with the injectors. Bummer. Sent from my FlashScan V2 using Tapatalk

    No start issue.

    Agreed, it sure sounds like the wires weren't tightened on one or more injectors. Been there, done that. It will ohm out fine, but drops injectors as soon as the motor starts vibrating as it starts. As much as it sucks, I'd pull a valve cover and verify the injector harness is tightened to spec...

    The deposits from the EGR look pretty normal. The soot from the EGR won't build up much, but if oil vapor from the PCV is also coming in to the intake, soot will stick to that and build up thicker over time. If you do a PCV reroute it will help prevent future buildup, if that is legal in your...

    2008 4wd LMM w/ weird problem. Trans for TC related. I'm at a loss

    Is this in a Kodiak, or did you install the divorced transfer case out of a Kodiak into a regular pickup? Can you describe what the problem is in more detail? Do you feel it like someone stabbed the brakes or just a sound/RPM change? Does it happen right at a shift or while you are sitting in...

    Bought a Sierra as Donortruck - now he stay

    Sorry, I forgot to get this information for you. Here are the paint & interior color codes for my truck: Exterior: 815K = arrival blue Interior: 522 = tan leather In my opinion, the best colors GM offered on these trucks are 815K (arrival blue) like my truck, and the dark green variants they...

    2011 LML Allison LCT 1000 Swap

    I'd love to see some pictures of the interior! I've always dreamed of putting an Escalade interior in mine too, glad someone has actually done it. Sent from my FlashScan V2 using Tapatalk

    Aah, I must have mis-remembered what the transmission shop said. I only touch the software, transmission hardware is black magic to me. Sent from my FlashScan V2 using Tapatalk

    2011 LML Allison LCT 1000 Swap

    What is your 6 speed calibration based on? The only ones I know of out there are Suncoast (a lightly modified 2005 LLY file and a modified 2003-2005 VB), DuramaxTuner (fairly modified 2005 LLY file with a 2011+ VB), and PCMP (probably the same base file as the Suncoast, you provide the VB). My...

    Thanks, not a lot of trucks in this color (Arrival Blue) out there. The offset is about perfect to tuck in as much as possible but still allow full steering. This wheel/tire combination is the original equipment on the Hummer H2, so it works very well. But the Hummer H2 has a different front...

    Bought a Sierra as Donortruck - now he stay

    I am running 2005-ish (forget the exact year) Hummer H2 rims, so they are factory GM. Tires are BF Goodrich All Terrain KO2 315/70R17. You can see the bottom of the front blue plastic on the bumper has been trimmed to clear the tires when turning. Not pictured is the cab seam which just gets...

    Bought a Sierra as Donortruck - now he stay

    Since you have a GMC, you can run bigger tires than the Chevrolet. I run 315/70R17 tires on mine without a leveling kit. You will have to trim the front bumper plastic so you can turn. There is a seam on the cab that I also had to fold over flat with a sledgehammer. But the suspension doesn't...

    Rear Seat lift to accommodate sub box??

    That looks like it is for the Lux Bose setup, not the typical Bose setup found in the pickups. I didn't know they made one for that, good to know. Sent from my FlashScan V2 using Tapatalk

    anyway to unlock efi live tune

    If you do manage to get an unlocked tune, I have been slowly adding the 6th gear tables with CAX files. I use these with both the Duramax Tuner tune and a PCMP tune. Grab the CAX file here...

    What did I get myself into..

    What size is your exhaust? What I've read says any resonators to address drone need to be as close to the engine as possible, so it might do better if it was farther forward. Sent from my FlashScan V2 using Tapatalk

    LLY Ficm

    My brother owned one, and it would always make me nervous while cranking, as you wonder "is it gonna start today, or no?". The answer to that was no one too many times, and he went back to the LB7 club with me

    LB7 Fuel Level Sensor Scaling

    If you have a Tech 2, you can command all the needles to 0 or 100% of scale, makes aligning them pretty easy. Just install it in the truck with the face off. The low fuel light should come on regardless of the needle being wrong, so if that didn't happen, you might have another issue. I had my...
