When my mechanic replaced an engine into one of my Z's, the engine was
"sticky" and would NOT turn over at all.
He injected some ATF into each of the cylinders and let it sit for a couple
of days. Then with a 1/2" ratchet and socket on the main crank nut, he tried
to turn the engine over in one direction, then the other. He'd do this
several times, then would push it in one direction and let it sit. This
went on for a couple of days and slowly but surely he got the engine to
begin turning over.
The end result is that he was able to finally get the engine to turn over
completely with the ratchet. He mounted the engine and electricals and
started her right up.
I'm not sure if there was any scoring or damage to the engine, but it
doesn't burn oil, nor other problems.
It might not be the "perfect" fix, but a complete engine swap for $500
ending up with a running car, can't be beat.
FWIW
