Our 1130 had identical symptoms and we replaced the radiator,which contained the oil cooler. An external oil cooler is probably the better solution.I have seen some on white 2-105 and oliver 1850 tractors. Hot engine oil at 40psi or more will boil your radiator quickly and radiator cap is maybe 10psi or less. Joe   [Reply]   [No Email]

Didn't you notice any oil present in the water when you removed the head? Did you check all of the bores before refitting? Is there an oil cooler at the bottom of the radiator? The gist of what you are saying is that the cooling system is becoming pressurised by oil under pressure from the oil pump. This pressure is enough to cause the radiator cap to blow. Is this correct? Any block cracking is more likely to allow water into the oil. A cracked liner and perhaps a cracked or damaged parent bore should only allow loss of compression. Suggest checking all of the galleries up to the rockers and turbo just in case there is a blockage or significant restriction and the oil has forced its way through the head gasket and into the water jacket.
