Seal Well Cube

Ok, I contact the rebuilder regarding the leak and he suggested trying a product called "Seal Well" that come in a cube. You break it up and put it in your radiator water and he said 99% of the time it takes care of the leak.

He said if that doesn't fix it then bring it in.

Anyone ever hear of this stuff?

This is stuff he says only rebuilders can get. Not the stuff you get at the local parts store.

just do it right man! your engine has a pretty clean interior now (cooling passages) so why clog them up? i think the rebuilder just doesn't want to deal with it. take it back to him to do it right. i'm very leery about putting "seal stoppers" of any kind in an engine. they are more like a band-aid fix.

well, he'll have to pay the labor somewhere else... oh-i guess he could just do it himself too. too bad the rebuilder gave him bad advice....

Bill, I am not familiar with that product so I can't tell you whether to use it or not. One product that I have used and many racing engine builders use is Moroso Ceramic Engine Sealer. This product does work, but I never used it on anything with a heater (race vehicles only). If you use any of these sealers, I would recommend looping one of the heater hoses to eliminate the heater core from the cooling system temporarily. The Moroso stuff does not have any solids in it, but it does have a ceramic compound that hardens when you drain the water and leave the engine sit for 24 hours. I would do this as a last resort, but IMO, if the gasket is leaking, the engine builder is liable for it, not you. He gave you a warranty and an engine that leaks coolant. Now I don't know if this is relative to the head bolt fiasco or not, but you should demand that he fixes the problem. You paid for a properly assembled engine, and if an engine is leaking coolant through a gasket surface, it obviously either was not assembled properly, or one of the mating surfaces on the head or the block is not within specs. Again, you should not have to endure any crap for an engine that is warrantied.
