Seized Ford Engine

[Dave Page]

Hi,
try a pint or two of diesel fuel in each of the cylinders via the spark plug holes, and some down her throat (for the inlet valves) let it soak for a couple of days. Remove the cover from the flywheel and using a pry bar (not a screwdriver) in the ring gear, taking care not to remove a tooth. Inch the flywheel in each direction a bit at a time till she frees enough to allow free turning with the crank handle. You will achieve much more purchase against the ring gear than you or your strongest friend could ever assert with a crank handle.
Good luck,
Dave
