baccaruda Posted March 17, 2004 Share Posted March 17, 2004 uhh.. you may be the one to tell US how long that lasts.. I believe that's a new approach. good luck! Link to comment Share on other sites More sharing options...

Danbob99 Posted March 17, 2004 Share Posted March 17, 2004 what car are you driving? is it the crack between the vlaves? or some where else on the head? Link to comment Share on other sites More sharing options...
bratsrus1 Posted March 17, 2004 Share Posted March 17, 2004 Hi Eqvance This is Jerry, well the old timers call that stuff water glass and it works. Alot of flat head of flat head V8s were repaired with that stuff. Where can you still get it because i would like some of it. Thanks Jerry Link to comment Share on other sites More sharing options...
eqvance Posted March 17, 2004 Author Share Posted March 17, 2004 i never new where the crak was. alli know is that i was getting steam out the tail pipe and losing water. so i tried this liquid glass & it worked. just wanted to see iff i could find some else that's used it to get an idea how long this stuff will hold. thanks Link to comment Share on other sites More sharing options...
Meeky Moose Posted March 17, 2004 Share Posted March 17, 2004 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..

moosens Posted March 17, 2004 Share Posted March 17, 2004 So,where did you apply the LG? Link to comment Share on other sites More sharing options...
Meeky Moose Posted March 17, 2004 Share Posted March 17, 2004 you drain the radiator, flush good until there is no more antifreeze, then dump in the waterglass and fill with water.. its that easy.. Link to comment Share on other sites More sharing options...
Danbob99 Posted March 17, 2004 Share Posted March 17, 2004 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 Link to comment Share on other sites More sharing options...
subarubrat Posted March 17, 2004 Share Posted March 17, 2004 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. Link to comment Share on other sites More sharing options...
Danbob99 Posted March 17, 2004 Share Posted March 17, 2004 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 Dan Link to comment Share on other sites More sharing options...
subarubrat Posted March 17, 2004 Share Posted March 17, 2004 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.

Danbob99 Posted March 17, 2004 Share Posted March 17, 2004 sorry, by that last one i was trying to see if there was anything it could damage, like sealing up on the valves themselves. Link to comment Share on other sites More sharing options...
Meeky Moose Posted March 17, 2004 Share Posted March 17, 2004 doubtful.. the stuff is the same thing thats used to make a cast harden btw.. another .02 of mine.. i've never used it on a soob, but have used it in fords, chevy's, mitsubishi's, toyota's.. had good results in all cases..

scubaroo Posted March 18, 2004 Share Posted March 18, 2004 :argue: I would not use this. this is used car sales cure, ie saw dust in trans /diff, painted hoses, greased belts. use this only in an emergency! IT IS NOT COMPATIBLE WITH COOLENT/ANTIFREEZE. Link to comment Share on other sites More sharing options...

heartless Posted March 18, 2004 Share Posted March 18, 2004 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!!
