In that case, I suggest that we don't jump to conclusions about anything until you do.

That's what I'm saying. Usually all the valves would be bent if the timing was off.
I just did the leak down about an hour ago.

Yeah I can't wait to see what's up with it. I'll report with what I discover once heads pulled.

They should all be squishy. I bent valves on my engine turning the cam to TDC from lifters holding valves open and valve to valve contact. Pistons were all in the middle of the stroke.

Finally pulled the head. No visible marks from valves hitting pistons. Put break part cleaner in the Intake ports and valves are seeping fluid past them.
