My 91 250 got some water in the #6 and got stuck from sitting. I pulled the head off and got her spinning again but need to find the source.

The heads were changed in the past and it and the gasket both looked good. I took the exhaust cover off and things look good there also. There is almost no salt in the motor and I checked closely with a flashlight and see no corrosion.

Before I put it back together does anyone have any ideas?

A friend said something about a lower crank seal. Is there a way to check that?

The more I look at things #4 might have gotten some water too.

Actually I think #4 just had surface rust from the piston being down and the ports being open.

Anyone?

I guess I'm on my own with this one.
