I used water glass in a MF 150 with compression leak into water jacket. did not work. Seems head is now glued down from water glass in right rear corner. Broke the lifting bracket pulling with overhead chain fall. What next?
Lift again while hitting around with hammer?
 
Is it a diesel? Look in the MF archives on here. It is mentioned that the 3 cylinder Perkins can have problems with carbon keeping the head from coming off. You should mention what tractor and/or what engine in your heading. Head stuck down, nobody will know what you're talking about. Dave
 
If it really is water glass thats holding your head on,did you have it running when you poiured it in?How much did you pour in it?

If you poured it in while it was running,and kept it running while it was circulating,and it stuck the head on,I dont know what you could do.Maybe somebody knows.I think maybe heat would soften it up,but thats just a guess.Maybe hook a hoist to it and heat it with a torch where its stuck,but first look real close and see if there are any bolts you missed.
 
Hi Mel,

Sodium silicate (egg whites) can be disolved in hot water, above 210ºf. That's just about the only cure if that is indeed your problem.

IMO, I'd be looking for a head bolt you missed.

Hi Walt,

I'm not a chemist and was just reading the label off the jar. Different types of sodium silicate with simular properties?

Doing a google search returned some uses for sodium silicate that I have never even heard of.

I see I did make a error tho, as it will combine too set at 210º/220º but it takes over 1500º to recombine from glass state to a liquid.

That isn't what I found when I added to much to a diesel too seal a head gasket leak where I plugged up the water pump and suction hose. Here I just used water and engine heat to flush the crystals out. I never could get the heater core unplugged.
