1949dodge Posted July 19, 2009 Report Posted July 19, 2009 well I thought I had the motor freed up. guesse not. or maybe. heres my question. my car has a gryo matic. Is there anything in the trans that could have broke in 59 and would case the motor to become stuck with the engine. also I didnt pull the starter. could the starter drive be stuck into the flywheel. I think #5 is still stuck. but with a 4 foot pipe on my breaker bar outta done the trick. on the rear of the motor does it have a flywheel and plate like a normal car with the "coverter" behind it. I never had a motor this tuff to break loose... what do ya think? How long does one have to let the motor "soak" remember has been sitting since 59 Quote
PatS.... Posted July 19, 2009 Report Posted July 19, 2009 Nothing in a Gyromatic should stop the engine from turning. If you think it may be the starter, simple enough to pull it. I would pull the head and pan to have a look if it's been sitting that long. Mine had a broken valve and a large mouse nest on the oil pick-up...unlikely to start and wouldn't have run long if it did. Quote
1949dodge Posted July 19, 2009 Author Report Posted July 19, 2009 yep did all that pulled the head soaked it tapped it everything. one piston still will not get wet around the skirt. the rest got damp on the bottom. pulled oil pan. nothing seems outta wack./ Quote
greg g Posted July 20, 2009 Report Posted July 20, 2009 soak it up again, disconnect the rods from the crank, rotate the crank for clearence and use a bfh and a block of stout wood to strike the top of the pistons that are stuck, The vibration from the blows might hepl to dislodge some of the stuck ness.

JerseyHarold Posted July 20, 2009 Report Posted July 20, 2009 In my experience, flathead sixes are more difficult to un-seize than other engines. As Greg suggested, use a bigger hammer and block of wood. Quote
stellarrestorations Posted July 20, 2009 Report Posted July 20, 2009 I've used dry ice on a stuck piston to shrink it and also help loosen the bond between the piston and the cylinder walls. Quote
