Here's a question for all those who use their tractor in the winter. How do you keep water vapor from freezing and clogging the oil breather?

The only solution I can see is to take the breather indoors after every use and dry it out.

We've been getting some pretty big temperature swings lately and that's causing some condensation to form in the engine.

Over the years I have noticed condension at the breather on automobile engines and it appears that blow by is another factor causing this. The more blow by the worse it is.

Never heard of that problem before. It sounds like you have a lot of moisture in the oil. If it is condensation then I'd say you didn't have a thermostat or it's stuck open which means the motor never gets hot enough to flash off all the condensation in the oil pan. It just keeps accumulating. Another thing is to make sure you run the tractor long enough during cold weather. Short runs lead to increased condensation. If it isn't condensation, that's another thing. Could be more serious. Are you losing antifreeze? Is the oil milky? Do you have milky residue in the oil filler tube? HTH Steve 8N 169302

Hey Steve

Yeah it could be the thermostat except that the block seems warm when I've done with the snow. But it's worth looking into. Thanks.

There's warm and then there's WARM. It's hard to tell without a thermometer. There's been lots of discussion about needing a thermostat, but my 49 definetly runs better since I put a thermostat in it and I don't get that milky buildup in the oil fill tube. Good luck. Steve 8N 169302

I put a K@N filter on my N. # RU 0160. Remove oil bath. Put filter on end of tube. Tie it up so it won't flop. Takes about 10 minutes. Re-install oil bath in summer when dustier. Easy starts in winter. You may have to tweak your carb settings a little. My N started fine at five degrees. Helps prevent flooding.

Thanks Hilltopper but I think that you are refering to the air cleaner?

In my post I was refering to the oil breather. As the engine warms up, any condensation in the oil evaporates and is supposed to be vented out of the breather. However, when it is cold, the water vapor condenses, freezes and clogs the filter and tube.

I use my 8N all winter and have never had a problem here. Yes it does freeze up, but it never gets enough water fo freeze solid. As the new hot vapor rises it thaws. The ice that forms is usually an oily kind of slush rather than true ice. I guess if it did freeze solid I would have to thaw it out as you suggested. If it has ever happened to me I didn't notice. Ice in the gas tank from heat under causing condensation has been an issue. I always use dry gas or water remover in winter.

Thanks Snowplow, water in the fuel is such a pain. I use methyl hydrate 2 oz per fillup and always keep the tank full. No problems yet (knock on wood). I never noticed the breather freeze up until this year and I've been using the tractor in winter for 11 years.

I was having to dry out the inside of the distributer cap after about 45 minutes of work. When I took the distributer off to really dry things out, I noticed that there was that foamy oil scum on the back of the distributer. Apparently the water vapor has been collecting there, seeping in along the bushing and causing all sorts of ignition problems. Anyway, figured out the breather was clogged (frozen) and the problem seems solved. Ran it this morning for an hour and a half and no missing. I took the breather in to drain and dry after I finished.
