Drain the oil and see what you get..... I would throw some atf and marvel mystery oil, let soak in for a few days if you get water and see if you can turn it over by hand. All you are out is a few $ for chemicals.

YMMV

Juanprado is correct. Always see what you got prior to forking out cash.

Drain the oil and look for water. Add marvel mystery BUT REMOVE the glowplugs BEFORE trying to turn over so you don’t hydrolock. If you don’t open the glowplugs or remove the injectors and you pour in liquid or you have water IN THE CYLINDERS you will bend things and f-the engine up.

This is why I love this site. Learn so much and different ways to do things.
