Just my luck!!! I,ve been noticing a small amount of coolant level going down in the resivoir for 2-3 months but couldn't find a leak.A pressure test didn't show a leak either.Once in a while it would show in a small puddle on the ground but not always.Then it happen.While crawling around under the engine (4.0) I happen to see signs of a leak near the second freeze plug back from front.I ran it for a few minutes any it started leaking the size of a pin hole----very small----and then would seep down to a drop at the bottom.It would be impossible to get to it for welding or JB weld on outside without taking headers etc. off.Anybody have a suggestion on something to add internally? Those type products have never been a favorite of mine.

I would never add anything I internally to try to stop a leak. There is no way to direct it to the very spot you want it to go and it will clog up every port.
