so i have a blown head gasket, but im thinking about trying it for a last ditch effort. obviously if it does work, it wont last forever, but any period is better than nothing...


My friends dad used it on his old van, and its worked for almost 40k miles, but obviously Ive read a lot of times it doesnt...



has anyone tried it?

I guess the stuff is just made up of Sodium Silicate. I plan on just ordering a pint of it from a pharmacy for a quarter of the price and its supposed to act the same. Im not giving it much hope, but its worth a shot before I have to tear it down anyway.


"Automotive repair
Sodium silicate can be used to seal leaks at the head gasket. A common use is when an alloy cylinder head engine is left sitting for extended periods or the coolant is not changed at proper intervals, electrolysis can "eat out" sections of the head causing the gasket to fail.
Rather than remove the cylinder head, "liquid glass" is poured into the radiator and allowed to circulate. The waterglass is injected via the radiator water into the hotspot at the engine. This technique works because at 210–220 °F the sodium silicate loses water molecules to form a very powerful sealant that will not re-melt below 1500 °F.
A sodium silicate repair of a leaking head gasket can hold for up to two years and even longer in some cases. The effect will be almost instant, and steam from the radiator water will stop coming out the exhaust within minutes of application. This repair only works with water-to-cylinder or water-to-air applications and where the sodium silicate reaches the "conversion" temperature of 210–220 °F."
