(In the old days we would refer to it as the Bendix not releasing.) I thought it might have been worn contacts or plunger per other posts in the forum. Bought the contact kit above and replaced them and the plunger with the same issue continuing at even a few degrees warmer than before.
I've also replaced the starter and the starter relay, with neither fixing the problem.
I'm hoping to find out what is causing this and getting it fixed before it ruins the new starter, wiring or battery by causing something to overheat or burn up from sticking.
Any help is appreciated, thanks much!! Dave

Unfortunately it could be the teeth on the flywheel, if they are rough/chewed up to some degree they may not be letting the gear on the starter slide back away from the flywheel, the way the starter gear is released is from when the engine starts running the flywheel is spinning faster which spins the starter gear faster than the starter motor and the starter gear is forced by the counter rotation back into the starter, if the flywheel teeth are roughed up the gear can hang up and not be forced out of mesh by the counter rotation.
The next time you have the starter off try looking at the flywheel teeth, you may have to rotate the engine 1 rotation by hand as you inspect the teeth because it may only be a few teeth that could be causing this issue, if you find this to possibly be the issue you either can try filing the bad teeth a bit to smooth them out in hopes it will let the gear release better, or replace the flywheel which will be very expensive job I'm afraid.
