1997 Ford Probe Repair Question
Interference engine being obstructed by something. We re-timed it and it's still not spinning freely
An Interfernece engine actually will keep running if timing belt/chain/tensioer fails and will cause engine damage. Non-Inteference motors are set up to shut down to avoid damage usually by the distributor and crank position snesor beign out of phase.
You have an actual mechanical contac when turning by hand that will be worse if oyu try to run it and the vsvle stretes.
There must be some damage from the first timiing chaing and tensioner failure.
I am guessing the valves are bent and need replacement.
Lucky you have a bore-scope you can use, they are very helpful.
Let me know how things go.

I'VE BEEN THINKING ABOUT THIS ONE TOO
I HAD THE THOUGHT OF MAYBE PULLING THE PLUGS AND CHECKING FOR WATER IN A CYLINDER POSSIBLY HYDRAULICALLY LOCKING IT UP. POSSIBLE HEAD GASKET LEAK? WE SORTA EXPERIENCED THAT, WHEN WE GOT A BIT TOO FAR OUT IN A POND.
JUST A THOUGHT

Would like just to clarify that non interference engine doesn't use the cranckshaft sensor, but they are mechanically designed as the valves dont comme all the way down till hit pistons when they are on TDC (may be 1mm of space), impossible to stop the crankshaft movement at less than 1/10 of second, it's phisics laws.
