Default rusted piston rings

i have a 360 that has been sitting for 2 years, and now it wont turn over...

being that it turned over when it was pulled im guessing that the rings are "stuck" rusted, seized whatever

any remedys??

i tried 10w30 down the cylinders and let it sit and still nothing...

its on the engine stand so i can pull it apart, just want to know if theres a simple fix..

thnx

I like a mix of ATF and brake fluid to unsieze grumpy old motors. Pour, ignore, attack in a few days.

I've heard of people using PB Blaster...

Spray in the cylinders, let sit for a while....few days than turn it over with a socket.

A 258 sat in my yard for 2 years uncovered filled to the brim with water.

I pushed it over - dumping out all the water, pulled the pan and cleaned out the sludge.

I thne pulled out all the plugs and dumped a few ozs of atf down each cyl and a few ozs down the carb.

Hand turned with a breaker bar, then cranked with battery (plugs left out),

put plugs back in , started right up and ran for 2 years until i sold the jeep.

Fuel oil / diesel works well. Have used them to loosen up a couple old tractor engines. Let it set a couple days. Too bad there is no easy cure for the rust pits that will remain in the cyl wall
