Can Marvel Mystery Oil Unseize an engine?

The MMO will allow you to remove the pistons from the cylinders so you can fully disassemble the engine to rebuild it properly. MMO is not some kind of magic fix for an engine that has seized because it ran out of oil or it severely overheated or both.

How do you fix a locked water engine?

First, the water must be removed from the cylinders. The spark plugs are removed and the engine is cranked over. In engines that were hydrolocked at idle or when the engine was not running, it may be all that’s required to clear the obstructing water, so removing the spark plugs isn’t necessary.
