stinking water neck driving me crazy

FLEX SEAL!!!! IT MAKES BOATS FLOAT AGAIN! ;)
We're talking ford here, that's the anchor, not the boat

Leaking through the bolt threads because they go i to water passage? Just a guess.

I did not think they go into the Water, but both times I put some aviation permatex on the bolts, just to be sure

Let the goop dry before adding coolant maybe?

Did a minimum of 24 hours each time...as per instructions



Thanks for all the input guys, I will check for flatness and re assess the situation
