Ever get anywhere with this? I’m having similar issue, engine jumped timing and won’t run. I can spin the cam, the timing chain turns, but the crankshaft doesn’t. I was actually able to screw around and get everything longed up again and got it to run for 10 seconds. Everything looks new, that I can see. Worried gear on crank issues. Only 4 years old and couple hundred hours on it. With it being a press fit, I’m thinking no way to replace with engine installed. Hope you got yours running again. Mines been down for a few months and momma wants it back running. Maybe I’ll just drop a 5.0 coyote in it. Lol
