    I think I may have a cracked piston, but some things don’t make sense to me. I’m not sure what’s all involved with a cracked piston other than an excessive amount of blow by. I was on the highway doing 65 when my truck started shuttering. I thought it was my transmission and it was driving fine...

    I own a 2006 Chevy Silverado 2500HD LBZ Duramax with a sun roof. I am having trouble finding parts for it. The previous owner said the tracks were cracked and that’s what was causing the leak. Does anyone know the part number or an aftermarket fix? The dealership says all the sunroof parts for...

    I drive a 2006 Chevy Silverado 2500HD LBZ and I noticed this week the acceleration has been spotty, not as responsive or torquey in comparison to even last week. I have read that it might be the Accelerator Pedal Position Sensor? Any thoughts? Has anyone had this happen before? Here is a little...

The truck will crank for a second then act like the battery’s are dead when they’re not ,windows and locks don’t work , interior lights don’t go off, sometimes the radio stays on.

    2006 LBZ engine rebuild I’m doing an engine rebuild and am getting the Mahle Original pistons. Standard size, and standard compression. Do I need to spend the money on an alternate fire cam? Or will a keyed stock LBZ cam be fine?

    I had an injector stuck open and it ended up torching a hole in my #4 cylinder. I’ve decided I wanna keep the truck so having a shop do this right the first time is very important. This is my first time dealing with an engine rebuild. I’ve decided on the Mahle Race Cast, do you think stock rods...

    I was on the highway doing 65+ when my truck started shuttering. If I kept off the gas and let it coast all was well. I drove for another 25min to get closer to home. I pulled into a Flying J and my exhaust is pouring out white smoke. It’s idling super rough, like it has a truck Norris cam. I...
