This past weekend I bought a 1964 Farmall 706 with a 263 gas engine. Tonight I was checking some fluids and noticed signs of coolant in the engine oil. I need to let it sit and crack the drain plug to double check my suspicion. The radiator is full so this is a little surprising. My first thought is a possible head gasket problem. Were these engines known to have head issues? If I have coolant in the oil I plan on dropping the oil pan and pressurizing the radiator to try and determine where the problem is. I am just curious what you all have ran into on this engine? Thanks.
