Yep your not really going to know what happened until you start to get some visual feedback on it.

I was trying to think of what would cause two cyl. to loose all compression yet allow the engine to turn over and start.
Hole in both pistons very unlikely.
I thought maybe a busted cam with valves stuck open.
But you would think a piston would hit a valve if it was stuck open.
Then all kinds of things can happen.
So I am curious as to what happened.

They said the pistons looked good. hoping for busted valve spring or a stuck lifter but i’ve already got a used head and cams priced out. just gotta get the car back and tear into it on a weekend

Maybe it is a broken cam or something in the valve train.
Keep us posted.
