He hit it right on the nose with the brake fluid, in years past, i managed to
freeup a frozen morris mionor engine block with brake fluid. had to let it sit
for a week or more, but the engine turned freely when done. the brake fluid
will ruin pot metal parts if left imersed too long. the pistons did show some
minor pitting, but the engine ran fine after a minor rebuild.
another great rusty part disolver, is a product called TASCON, which is the
chemical that they use to put the odor in natural gas. ( can be hard to get)
