My tractor has milky looking oil with a green tint. That tells me antifreeze in oil. I checked the head bolt torque and it is fine. I pressurized each cylinder with 100 psi of air looking for bubbles in radiator, none found. I have the oil pan off looking for any green drops, none. When it runs there is no white smoke or bubbles in radiator. I have the radiator under a few psi of air pressure right now. I am looking up into the crank case and can't find anything wrong. Nothing around the piston sleeve O-rings. Nothing in the pushrod oil return passages. No antifreeze drops anywhere.
What am I missing? Next step is pull the head but I would like to have a sound diagnosis first if possible. Otherwise replacing the head gasket may not do anything.
