Decided to change the oil on my 1950 Farmall C. A few drops of water came out the drain plug and some on the fill cap. Welcome to Indiana. We have condensation problems a few days in the spring and fall. No, I don't have a head gasket issue. Engine has been rebuilt and it doesn't use oil either, good rings.

The old tractor doesn't have a thermostat or even a water pump, so unlike most modern engines, the temp guage doesn't move off cold, except on a very hot summer day.

I use racing fuel in the old girl, makes it run faster. Not really, a friend gave me the can. You look you can see condensation on the can.

It would really be a good idea to put in a thermostat and restrict the bypass so it will warm up good when using it.

The bypass is about 1/4", and only needs to be big enough to let it bleed, maybe 1/8".
 
I know what you mean. Our shop floor sweats real bad. It's like a skating rink any place there's oil.
 
That engine has no place for a thermostat they didn't need one when new and still don't his observation is nothing new engine have been doing that since forever you younger fellows don't know anything how we used them when new and now think they are like present stuff. They are simple and last forever that's why they are still running and your new stuff needs add on stuff to clean whatever and mickey mouse wiring safety junk because someone thinks its necessary. No doubt those old ones will still be running another 50yrs and there is no promise the du-funky thing al-ling stuff will still be available for stuff being sold today as many many parts are rite now not available for something 10-15yrs old.
 
In sprite,you are correct Gene. However preventing water mixing with oil is better for any engine,old or new. I went so far as putting pcv and coolant recovery on my classic cars. T-stats,water pumps and fan shrouds extend engine life regardless.
Nessary? No. Helpful? Absolutly.
 
So how many hrs per year do they get used not even enough for an oil change its fine to add that stuff but you will never use them enough to know if it helps. My point is the old tractors worked fine for yrs without all the modern stuff before EPA started playing.
 
This tractor is 66 years old and engine runs just fine. Even in the winter after I shut it off, I can hear water moving inside engine and radiator. In the summer, even thought the thermometer hasn't moved, the engine needs to cool down 5-10 minutes or it will diesel. I even replaced the thermometer thinking it was bad, no change. I'm not going to do a thing to change the cooling system.

I did loosen the tranny/rear end drain plug, no water.

I bet if I were to loosen the engine drain plug, there wouldn't be anything either.

Rarely do I have condensation issues, but this is the time of the year when it shows up in where I live.

Same with the oil fill cap, rarely is there condensation on it. Problem is a relative humidity/temperature issue I've lived with for decades. Welcome to Indiana weather. If you don't like it, wait it is always changing.
 
You are absolutely right. All my tractors get a roof. Not going to heat it when my problem only exists a few days a year.

Good reason to change oil often.
 
I check every gearbox and crankcase in the spring . The bigger tractors (depending on the winter)seem to have the most if any condensation. Twice this winter the complete tractor was covered with condensation.
