    Hi guys, I’ve been chasing a noise recently. One is coming from my oil pan and humms / buzzes like an LML with a bad oil pump. However I can’t find anyone who has the same problem on an Lbz. Should I change my pump? Or is it normal? Please let me know!

    Hey fellas just seeing what your street/strip trucks are running for piston to bore/wall clearance for a Mahle cast piston. Primarily want to be setup to be a daily driver, truck will see a MAX of 55 PSI, 16.5 CR, 4500 RPM, with 60 overs. I would guess no more than 750 to the wheels very looking...

    Hello, i’ve got an lbz duramax leaking about a gallon of coolant into the crank case in 5 minutes. I’ve been doing a bunch of research and have seen it can be the water pump and head gasket. i’d like to think it’s the water pump but it was just replaced 3,000 miles ago. I had a shop diagnose it...

    My 2006 lbz with 284k miles on it went into limp mode after driving it a little aggressive. Code p0087 (low fuel pressure) we hooked my cousins scanner up to it after limp mode reset and drove it pretty hard and it had the correct amount of psi and didn’t go into limp mode. This has happened...

Can I swap bell housing to solve this issue? If so, how technical is that project? This would be an in field swap...

    I have a 2006 lbz duramax and I am considering selling it and going to a 4th gen Cummins. I am torn because the lbz was and is my dream truck, but it’s at 250000 miles now. It will need new injectors and lots of other work done this year which is why I’m considering switching. If I do keep it id...
