Also I couldn’t see if the crank pin was still on the snout but the next crank u get make sure it has a key way machined in it. This is somewhat common of a problem on the duramax it shears the stupid pin and the damper starts wobbling around or the reluctor wheel spins as well and your timing gets thrown off and bam u are where u are now.
I’m not sure but I’m about to go through the same thing your going through I’ve got a crazy knock but no metal shavings in the oil was really hoping for a fuel knock 🤷🏼♂️
Flip it over and pull some main caps and inspect the block before u keep going. If the crank damaged the block u are wasting your time. You are doing the right thing by pulling the heads but u don’t have to pull them or the cam to do it on the cheap. There should be some threaded holes on the reluctor wheel and I think it’s m8 1.25 get some bolts and use them as a pusher or just pull All the main cap side bolts and vertical bolts then pull the crank out without pulling the other head and cam. If u are worried about seeing the valves and cylinders pull just the injectors and bore scope it.
Fellow Houstonian here, just subscribed to see the conclusion to this.
