I've done several 6.4 engine removal and installs cab-on. This is only because I do not have a lift. It's not terrible but the biggest complaint is having to be under it taking the bell housing bolts and engine mounts loose.

Someday I'll have a shop with a lift...

Thanks for the advice, guys.

I'm worried about further damaging the engine by turning it over/ running it.

What is the relative compression test going to tell me other than a cylinder is bad. The next step will be to pull the heads, right ? Why not just go straight to that ?

Am I wrong to think that the noise is for sure caused by a mechanical issue, like cracked piston, bent rod, valve train damage ?

would suck to pull the heads an find out you just had a bad injector. Based on your responses, you arent interested in doing any diagnosis. Good luck with it.

power balance test, relative compression and shutting each cylinder down individually to see if/what changes.
