    LLY: Black Smoke and no power

    Picked up an 05 LLY with 189K that a guy was tired of messing with with the hopes of getting it running for a beater truck. It was a trade in and then supposedly went in for headgaskets at a local shop and it still doesn't run right. I don't know all of the details, but it has definitely been...

    LBZ: P0116

    I've got a 2007 Classic LBZ that keeps throwing a P0116 DTC and turning on the MIL. It came on the other day when I went to start it and the glow plug light never went out. After about 30 sec of waiting I went ahead and started it and the MIL came on, glow plug light went out when it started...

    Oil leak- Oil drain??

    I have an oil leak that comes from up top at the rear of the engine on my 02. I'ts been there for several months. It comes around both sides of the bellhousing. I had the top end apart for injectors not too long ago and didn't see the cause while I was doing that. It doesn't leak alot, just...

    Bought myself a christmas present

    I got a good deal on an 02 Duramax engine and Allison transmission tonight and my plan is to sell the transmission and keep the engine around to build as funds allow. I'm sure I am living on borrowed time considering my signature. I don't really know alot about engines but I have learned alot...

    Allison 5sp: blinking R and clunk in drive

    Hooked up to the camper with the '02 this weekend and got to the campground fine. Once there I tried to back up and had no reverse. The R was flashing and then I put it in D and touched the gas and it revved and clunked into gear. I drove to our campsite (found a pull-thru luckily) and still had...

    LB7: Diesel Leak after injector replacement

    Any tips on finding a diesel leak after injector replacement? I just replaced mine due to fuel in crankcase- balance rate were fine. Now I have a stream of diesel coming out the rear main seal with the new ones. I plan on hooking up EFI Live to see if I see something retarded on one injector to...

    Allison 5sp: Converter locking too hard

    I've had my PPE stage IV trans with an ATS 5 star converter installed in my 02 for a few years and have put about 35K on it. Trans has never skipped a beat and it shifts fine. A few months ago I noticed that when the coverter locks at about 55mph it feels very rough. When in T/H it locks real...

    Are my injectors too old to hone out?

    I've got 87K on my stock 02 LB7 injectors. They seem to be perfectly fine and balance rates are perfect. It is time for some improvements in the fuel department this winter. I will be putting on dual fuelers or a stroker pump and would like to do something with injectors also. I can get my tips...

    rotating motor by hand

    Which direction does the balancer normally turn when looking at it from the front of the truck? Is it clockwise? I saw somewhere that you can turn the alternator counter clockwise to rotate the motor also, is there any harm in doing that while adjusting valves?

    I thought it was headgaskets

    I started the head gasket job on my 04 LB7 due to pressurized coolant system. The problem only showed up if I was towing something or ran the dog **** out of it. I fooled around for a while and decided it was a headgasket or injector cup. The truck has 139K on it, the injectors were replaced...

    Truck falls on face with new turbo

    I put a Silver Bullet 66mm on my 02 about a month ago and I have been getting a big defuel or something at around 80-90 mph WOT. I have been running a hefty EFI tune from Fleece on it for about a year and it ran good with the stock turbo, but now that I put the turbo on with the same tune it is...

    Truck dying every 2 minutes

    My truck starts and runs for about 2 minutes and then dies, I've tried it over a dozen times and it is almost exactly 2 minutes every time that it dies. When it dies it shows DTC P1626 "theft deterrent start / fuel enable signal lost". Truck runs and starts fine, just straight up dies like I...

    EFI asking for another license??

    Not sure what happened, but I screwed something up... I read the current tune on my truck because I wasn't quite sure which one I had loaded and have been playing with some. I then went to try and check balance rates and none of the diesel pids would show up, and it was showing a wierd vin...

    Help - LB7 won't start after turbo swap

    Just got done installing a Silver Bullet turbo in my 02 LB7 this morning. Truck has had the batteries disconnected and stock turbo out for about 2 months. The truck turns over, builds oil pressure, it is just not firing at all. I plugged the block heater in about an hour ago (never used it...

    Video- Is this too much shaft play?

    Bought a used Silver Bullet, guy said it had 10K on it. It has no axial shaft play, but the radial movement caught my attention. It spins freely in the center, but if I push it to the side it has a decent amount of resistance when I try to spin it. It doesn't look like the wheel touches the...

    How much do wider wheels help?

    Is there much of a difference in going from the stock 16x6.5 to a 16x8 while running a 285? The reason I ask is that I have half worn MTR's on my stockers and I like those tires for pulling. My other truck has 16x8 wheels with almost new Maxxis Bighorns, but I don't think they would pull as well...
