Water? in TO20 oil fill

I have a TO20 that runs great. I have noticed some condensation in the filler neck after running it hard. I cannot see any drop in the coolant level and I cannot see anti freeze in the oil. It looks like water. Is there something I can look at that might be holding the moisture from combustion? Could the breather in the valve cover cause this? Im stumped...MIKE

Hey guys, The water in the filler neck is normal condensation build-up based on hot engine temps, ambient humidity and also from when you wash the tractor down after use. I have a '49 TO-20 and I have converted her from the old draft tube to a PCV valve system, I have no water loss, she doesn't run excessively hot and I still have the same milkshake look at the filler tube. I wouldn't worry about it if I were you.

Mike,

I have a 54 TO30 and niced this in my filler tube also. I ended up not only checking the dipstick, but, draining the oil and really looking at the oil for any sign of water. That proved to be overkill, no water was in the case at all. I also think this is just a normal condensation problem.

Mike,
I have a '54 TO-30 and it only has a crankcase draft tube that comes out of the valve cover;no breather. I notice condensation on the oil fill cap/filler neck without any loss of coolant and no other indication of water in the crankcase. I have concluded that that this slight ammount of water is condensate from either blow by gases in the crankcase or condensate that that forms in the crancase just from the outside air temperatures cooling down and condensing water from the airin the crankcase, etc. When you fire up and heat the engine to nomral operating temperature, this water vaporizes and the filler neck and the cap are cooled by the air that passes through the radiator cooling fan causing the water to condense on the cap and the filler neck. I think what you are seeing is normal. Hope this helps.

I have similar problems. I have a 1993 Subaru Loyale station wagon, I replaced the engine head gasket and timing belt because of coolant leakage into the eninge 2 months ago. later on I found excessive water condensing on the oil filler cap. the mechanics confirmed it is water , instead of coolant. I guess it is due to the air coming from outside relating loud noise in the engine. I do not know if I should have the lifters replaced, because it is hard to tell a bad lifter, or just check the o-ring on the oil pump(air may come from the worn o-ring) .

Yes it could, the breather allows any pressure that builds up in the engine to escape and it takes with it a lot of moisture. Are you changing your oil regularly too?
