The Stovebolt Site Forums The Shop Area Engine Shop 54 locked up solid

I just went through this with my 1956 235. It sat for 20 years. I could not budge it even with the methods above except the coca-cola idea. I only used coca-cola for drinking and cleaning the terminals on the battery when they were gunk up with corrosion.

It took me a while to remove everything minus the cam and lifters. Since the engine would not rotate I could not remove the clutch housing or flywheel because of the hidden bolts. I finially had everything removed, spending time off and on after a week or so. The only problem was the lifters were rusted in. I had the machine shop remove them because they would not budge.

My .02 cents is that if the oil in the cylinders does not work in about a week or two or coke idea (not really sure about that), just tear it down and start from scratch. I would not want to possibly create more damage to the block. If its stuck that bad it may need to be bored out. Just hot tank and magna flux it, if its ok then spend the money to have the crank checked and polished and cylinders checked and bored out if necessary, then go from there on your build.

Good luck with it.
