So I had a small fuel leak from a fuel line on my 2007.5 2500hd duramax. Figured screw it and brought it to a local highly recommended diesel truck shop. Had the fuel lines, tank straps, sending unit, fuel pump and basically everything but the injectors replaced for about $3,000. One week and...

I recently bought a 2008 GMC 2500 about 6 months ago. The truck has been performing great and hasn’t caused any issues, but I noticed the upper radiator hose was decently hard after a week of sitting. Could squeeze with one hand about half way collapsed. The truck doesn’t consume coolant, and...

I have a 2001 with blown engine . I have two options. I have a complete donor truck for 2008 LMM or a 2003 LB7 with wire harness . Both will be challenging . Both have around 150k . LMM has delete kit and efi live . 2003 has brand new injectors and 60 day engine warranty. What would be the best...

Hi everyone. Been looking at possible symptoms of HG failure on my LMM. Started with pressure after being shut off overnight, then slight coolant loss, and just recently seeing the temp gauge go from running temp, all the way down and then a few minutes later back up again within the first...

First time poster!!! I bought my 08 express 3500 about 5-6 years ago and it’s proved it’s self over and over again with very little money invested. Now I have the time and money to fix this thing up week by week! It’s so much better than a car payment. I’m no master diesel tech or anything, but...

I recently picked up a 2007.5 3500HD Extended cab long box with the 6.0. THis is the truck I've always wanted but it is missing the 6.6 and Alison to make it perfect. The 6.0 is a solid engine but nothing compared to the Duramax especially in the mileage department. Sooo, I am contemplating...

So yesterday I started my truck it was around 0 degrees out it started and immediately started to chug and blow smoke (my first thought was injectors)so I checked the balance rate and number 3 and 7 where out of spec so shut the truck off let it set and when back a few hours later and started it...

I have a 2008 Silverado 3500 that keeps making a popping sound under the driver floor board front end area. I can also feel it under my feet. At 35 mph and below, but not highway speeds. It happens when I come to a complete stop, when I accelerate from a stop, going around corners at low speed...

Just brought this truck to the shop on a wrecker. It's a 2007.5 LMM 6.6 in a Kodiak C4500 Cab/Chassis (Bus). While buying it someone rolled under it and cut off the CAT! According to the guy I bought it from it was running with no engine lights, Now it is throwing (3) codes. Even after flashing...

About the truck: 2008 Chevy Silverado 3500 LTZ Dually Completely bone stock with the exception of a PCV delete 103,000 miles Daily driver/tow vehicle for 34 foot travel trailer. About the problem: When the engine is at operating temperature, vehicle in park, press the accelerator and it sounds...

The truck recently had the cp3 and injectors swapped. The first mechanic most likely didn’t drain all the fuel from the lines so I’m thinking it’s clogged. But it is coming from the bottom of the injector bore. I’ve checked for debris in bore and cleaned it, got a new washer from the co I bought...

hey guys new here i got a 08 lmm that i recently had to put everything back to stock because of our lovely friends at the epa. Put everything back together tuned back to stock now i have a check engine light for p2033 and p0546 which is high voltage in both egt sensors. i find it weird that both...

I really like the body style of the LMM but Ik it’s when the emission things really started to come in to play. Would it be easier to build an LBZ and put it in or easier to just fully delete an LMM. JEGS offers both engines for sale with the bottom end and valve train for the same price. Any...

If I wanted to put an LBZ into an LMM body what problems would I run into? What I can think of so far is the wiring harness? Any tips

Hello, I have a 2008 LMM And I was towing my trailer in the Nevada mountains. Nothing extreme… my trailer was probably around 7000-7500lbs. Truck has 200k on it and when I was towing, my ECT got up to 230 degrees and so did my trans temp. My thermostats are about 1.5 years old so they’re still...

I have a 2009 LMM Duramax deleted and tuned with a fass fuel system. It will go into limp mode from time to time but leaves no codes in it besides P02B9 this last time it did it. The shop that just did injectors in the truck said it was do to water in the fuel. They have cleaned it out since and...

Hey everyone. I've kinda hit a bump in the road hear. I blew a shock on my truck and I think I've settled on Bilstein 5100 or 5160 as the replacement. I know the truck is lifted or leveled but I'm not sure how much. I measured the block under the rear leafs and they measure 2" so I'd assume a...

I have a 08 lmm and it has an emission compliant tune and an s&b intake. I have the dreaded p0101 code and reduced engine power. I’ve had the maf replaced and the Iat sensor I have cleaned the filter but for the life of me can’t get this code to stay away for good and it’s so random just drove...
