Sure, but go a few degrees past TDC and you're sucking water into the cylinder
(might try it with oil instead of water, however). How do you turn an engine
at a steady rate--no more than a few degrees a minute--anyway?
Used to know an aircraft mechanic who liked to find TDC by putting his thumb
over the spark plug hole while someone turned the prop. The end of his thumb
ended up in a cylinder (and no, the mechanic was no longer attached to it).
