if there is a small crak in the block, you can try some sodium silicate in the cooling system. many years ago we had an ac ll crop combine that had a hairline crack in the cooling system. the mechanic that came out put some in the cooling system and it cured it. here is an article from the net on it

Sodium silicate can be used to seal leaks at the head gasket. A common use is when an alloy head motor 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 pull the head, a jar of "liquid glass" or Waterglass (as it commercially known) is poured into the radiator and allowed to circulate. The Waterglass is injected via the radiator water into the hotspot at the motor. This technique works because at 210 - 220 C the sodium silicate loses water molecules to form a very powerful sealant that will not re-melt below 1500 C. This approach is often used by disreputable used-car salespersons to disguise a leaking head gasket.

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 C.
