Has anyone ever used a product called Liquid Glass for sealing up a head gasket leak?

Liquid glass

The only Liquid glass I have ever seen is a car polish that's been around since the 1960's....never seen one used to stop leakage

Liquid Glass, or sodium silicate, is what we had to use to destroy perfectly good engines during the cash for clunkers program. We added it to the crank case after draining the oil and ran the engines until they seized. That's the only thing I have ever used it for.

Yeppers,Us old timers have used it for years! You can get it at the pharmacy,costs about $20.00 a Qt.
Won't mix with anti-freeze,flush it with fresh water and run it with water and keep it topped off till it seals.Drive it at least 500-2000 miles to make sure it's sealed good and then drain it and go back to 50/50 coolant mix!:thumbsup:

We used to use BARRS LEAKS...

It was brown with pellets. Don't think it's around anymore. Supposedly lubed the water pump too.

I just used some Barz Leak not too long ago. It doesn't have those little brown pellets in it anymore but it's the same stuff (the pellets are now pulverized and mixed into the liquid).

Best way to stop a head gasket leak is to repair it.

:iagree:

If you realy can't do it right away then bars-leak works...I used it for the radiator on my Fiero...just remembered about that...i better see if i need to get to work on that. That was several years ago.

If teh liquid glass works, and down teh road you have to have engine work done, what kind of mess are you going to have to deal with whan you disassemble the engine. Ithink you will have peace of mind if you jsut fix it properly.

A lot.
I agree. Better to just fix it and be done.

Those 'pellets' are goat crap, I'm told it works good, I personally would never put it in a Corvette , I'd fix it or have it fixed right, unless it's a real 'beater' and you are gonna dump it. We have 5 'Tennessee Fainting Goats' so if anyone wants some high quality stuff I would be happy to send 'um some.

Additives like this are NEVER a permanent fix. BTW, A "Corvette" is nothing more than a SBC, like you'll find in a truck. Know how many cars had LT'1s?

The only difference in many respects once they are put in a corvette they break more and are harder to work on...:D
