hello,
This message is not about a car or truck engine problem, but that of a boat motor, i didn't see a classification for boats, so i thought i try this approach, to see if anyone could shed some light on my dilema. I have a 2006 Stingray boat w/ a 3.0 L,,, inboard/ outboard. It was cold the other night and i thought i had it winterized correctly, but apparently i didn't. I blew out a freeze plug from under the manifold and water/anti went spraying out of hole. I figured i could just replace the soft plug but upon closer inspection i see that i have 2 hairline cracks in the side of the block, which one oozes liquid. also i have water drops coming down from up above the manifold line. Could this be a head gasket? Now, do they make a sealer that i can put into the motor and seal it up, or am i toasted? Thanks, Gapster.

If there is a crack in the block I am sure you have to get a new motor.

I agree,with the engine fluids under pressure it would blow whatever type of seal gunk you put in your engine right through the crack.
