i used to use that to fix blown HG's.. works great if you don't put antifreeze in.. the antifreeze will eat the waterglass..

 

it can be found at most pharmacy's.. sometimes ya gotta ask for it as some places keep it behind the counter..

 

 

a guy in oregon had an escort.. it was waterglassed.. he drove the snot outa that car pizza delivering for a few years before it went again..

so how exactly does this stuf work? does it just bond to the crack there? why wouldn't it bind up everything else then? Is it triggered by being in the cylinder during detenation or something along those lines? instantly crystalize at the time of ignition? any one got a website or a link to it? this is good stuff, and i got cracked heads, so anything that could fix this problem i would be eternaly greatful for! thanks

The substance is sodium silicate. The compound flows into the leak on the head and when the combustion gases are present it is glazed into a very thin layer of silica glass. This repeats over and over until the glass layers build up to seal the leak. As the glass patch wears or fails fresh glass is layed down.

so is there any chance of it sealing up around the valves? since water is getting in there anyways? sorry if i keep buggin about this, but if i'm considering using it, i don't want to worsen anything, i can't quite afford to fix it yet.

thanks

It is reasonable to assume that anywhere it is exposed to combustion gasses it will form a glass patch. So it would depend on the nature of the crack, in an intake valve passage it would do nothing, but for an exhaust or intervalve crack it may very well work.

doesnt sound like such a good idea to me, unless you live somewhere that never gets to the freezing point.... Besides, running straight water in your cooling system really isnt a good idea anywhere you live, but especially here in the great white north....we are still in the freezing temps range....I would have a dead Subie in just one night!! :eek:
