Liquid Glass???

Anyone ever have to revert to using Liquid Glass to seal up a small crack in an engine block? If so, what results did you have?

Maybe this should have gone into the Technical Forum, I feel so "techy" today!!!!!

BTW...I won't hold anyone responsible if I should decide to try this method.

Yes it works, when I was a kid the man acrosst the road used it to fix flat head V8,s with it. But there are many good sealers today so why not use one of them.

You gotta' know WHAT you're doing, when you mess with WATER GLASS!!!! If you get some of it hardened up in the RADUMATOR, you may as well JUNK it!!!----It's even "possible" to plug up small water holes in the block or head!!!! NO
Saw one car, where it "encased" all the top ends of the RADUMATOR tubes!!!

Update: I have a 'frostcrack' and I have some 'Titanium Putty' coming and have acquired the items needed to do the repair myself. I will be playing mechanic next week.

While sodium silicate (A.K.A. water glass, liquid glass) will seal a block crack and is part of some leak sealers, be careful where it goes.

A few years back, when the Fed gov'mnt decided to condemn all the old used cars sodium silicate was the toxin used to euthanize the engines. A pint in the oil and running it at fast idle for several minutes seized all the bearing surfaces and ripped up the crank journals. Screech! Locked up engine.

FWIW, the stuff works by reacting with carbon dioxide. End product: silicon dioxide (Quartz, the stuff sand and glass are made from). I used to use it as a sand binder in my foundry with E.P.S. patterns.

At commercial egg producers, eggs are washed, coated with Sodium Silicate, so the shell is impervious to bacteria gettin' in & spoiling the eggs. I have NEVER spoiled a raw egg, in my Fridge!---BUT, once I crashed 6, on the floor, when a cute Old Lady rang my "BELL"!

I'll try this Titanium Putty instead. Better than doing nothing and letting it sit there going no place.

You never said where the crack was in the block? Is it accessible from the outside? If so you can always use JB Weld. Just clean it up, V cut it and fill with JB and pattern like original casting and done!

That sure looks JB weldable to me

Just under the front lip...........this putty is suppose to be stronger than JB Weld.
