We build a lot of Duramax engines at the shop I work at and have a decent stock pile of stock good crankshafts, I did not balance it. It probably should have been but I found a crank with similar weight
@@EngelBuilt ok cool. I'll probably buy a new one so I wasn't sure if they came balanced or not. Was yours an lml crank still or do other cranks work too?
Long story with my dealer screwing me over, but long story short they used the old crank dowel which caused it to shear off and score the crank. Another dealer had confirmed my diagnosis, and my dealer ended up flat-bedding the truck back to themselves because GM won't cover the repair under warranty as it was my dealer's fault it happened. My dealer says they're going to make it ok and they've "ordered the parts", but here's my question... since they haven't even removed the engine yet and gotten into the crank, how could they even know what parts they need? Am I wrong on this?
Best thing for you to do, is to make sure you have your truck at a reputable shop that does a lot of good work and similar engine work to what your having an issue with. If that’s where the truck is currently, awesome next would be to get a lawyer involved, it’s a tough situation and certainly not the first time I’ve heard of something like this. There could have been a notable issue when the harmonic damper was reinstalled. But I would recommend getting a lawyer involved and get any and all documentation possible from both shops.
@@EngelBuilt thanks for the advice, shop it's at now is a GMC dealer who caused the original issue by using the original crank dowel pin when replacing the crank gasket
if your engine has low mile is it worth it just to change Brocken camshaft new bearings and not to spend the money on heads ?
How much cost repair this ?
Depending on what direction you go with upgrades it can get pretty pricey but this was a stock replacement crankshaft, bearings and gasket kit
Where did you source the crank from and did you have to balance it?

@@matd3150 so a lot of the aftermarket stuff is all going to be lbz based, like the crank, however this build I used a stock lml crankshaft

@@EngelBuilt dealer just called this morning, they say "GM changed their mind" and are giving me a new engine :)
Did it still run when the crank broke?
I purchased this truck not running. But they will run with a broken crankshaft
