I'm sure that the rings are stuck. Is there any "solution" that will unstick the rings? I know that this is the Stovebolt forum, but I couldn't turn the deal on the old Dodge.

It has done well for the past 5 years.
Good luck!!!

The old standard method of breaking in a new or rebuilt motor by accelerating and decelerating to "load" up the rings and help them seat will work. It did with my 50 Chevy 216. Or is it just a motor without a car? Now would be the best time to overhaul it without any sheet metal in the way.
