Stop Leak recommendation

[jerry witzel]

Go to your local pharmacy and get some sodium silicate, also known as water glass.

[Greg Reimer 7376]

If you have any water getting into the oil, DON'T use water glass. It would combine with the water or coolant and make a compound that would be destructive. On da last Prezzdent's watch, when they were buying back old cars to destroy them so people would replace them with new ones, they put about a quart of that stuff in the oil,ran the motor to deliberately destroy it, then scrapped the car. The stuff formed sharp hard glass fragments which destroyed the bearings, crank, piston skirts,and the block. Just what the al gore's of the world want for all of us.

Subaru Cooling System Conditioner , part number 35071,[ they don't call it sealer for legal reasons] works fantastic for small leaks .
We used it for Jeep 4.7 engines with cracked heads and it rarely did not stop the leak , and most stayed sealed up for more than a year.
2 small bottles did the trick and it only costs $3.00 a bottle.
I use it on one of my Big Block Chevy engines with copper head gaskets ,completely stopped all the weeping ,even with a 12# cap

I too have used the Subaru sealer and it was $2.00 per bottle. Great for ssssmall head gasket leakage. It is only meant for small leaks that Subaru had/has with their flimsy radiators. If you have a larger leak, then this may not work. British made product that resembles Bars.
