I have two Farmall 200's with the C125 gas engine. Both were blowing coolant out between the head and block. I pulled the heads on both, took the heads to a shop had them pressure tested, fluxed and milled flat. Installed new gaskets from Steiner and used a liquid copper gasket sealant from Permatex. Put em back together, readjusted the valves and had new sounding and running tractors. one started leaking again between the head and block. I put in a new temperature gauge and sender and temperatures run pretty cool. Even checked temps with a meter and thermocouple probe.
There is no pressure in the system and no signs that coolant is getting into the cylinders, so I'm continuing to use it. The heads were milled flat I'm sure of that. The block was cleaned till it was spotless. Headbolts torqued to spec and then some. Again only one of the two is leaking, and its not leaking much mind you, but after all the work I did, and the attention to detail I am disappointed to see any leakage at all. Any advice? Do these Farmall blocks have a history of problems??? Thanks.
