So I filmed it - cranked it - not turning
This is my home - 1996 Thomas School Bus - 7th Ciummins I've owned and I've done lots of mods from suspension swaps to Gov Spring upgrades and KDP's but I don't know internals.
Please help diagnose my next action item - I'm about to pull the front of the engine and asses
Thoughts please... Wiped out my account in Nov to tow it home - thought it was the fuel pump - out of curiosity filmed the cam while cranking... NOTHING~

 

Sheared Cam... But why?
