John Deere Gator water in the oil
Hi. I am new to this board. I have a 2008 Gator that gets water or something in the oil. Every 4 months or so it stops running and smokes unreal. When I check the oil the dipstick shows that the oil is half way up the stick and gray colored. I have the oil changed and all is fine until 4 months later when it does it again. I have no idea how this water can be getting into the oil? I never leave it outside and never went through a puddle the last time to see if that was how it was getting in and still it filled up again. I was wondering if anyone else also has this problem with their gator and if so how did they fix it? Thanks so much..

It could be gasoline, it could be coolant. If you have a vacuum type fuel pump, a torn diaphragm will permit fuel to be sucked backwards into the crankcase. Next time this happens, drain it into a clear container if possible. Otherwise transfer the entire contents into something clear. Then let it settle for a couple days, hopefully what's not yet emulsified will separate. At that point you might be able to tell what's in the separated layers.
Alternatively, give the condition time to develop - then let the machine sit for at least a day. If lucky, the contents of the crankcase will separate. Water will go to the bottom. Loosen the drain plug carefully and see what drips out onto your finger. After one or both of these tests you may come away with a better idea whether to start troubleshooting the fuel system or the cooling system.

I'd assume a leaking head gasket, except that's rare on so new an engine. As for it being fuel, I'd assume it would burn off pretty fast, but Greg knows what he's talking about.

Please Help..

Are you having to add coolant? If not then i like the fuel theory the best. It seems you would miss that much coolant.

Can you physically see water in the oil, or is there milky deposits on the valve covers etc? Condensation forms normally inside an engine and normal engine heat usually takes care of it. But if the engine doesn't get up to operating temperature on a regular basis, the condensation builds up and causes milky deposits. Obviously it has to be that in an air cooled motor. Certainly no one is going to pour water into an air cooled motor. Deere has bulletins out on the problem, they say the motors have to be run hot to get the moisture out of them. Short trips and light use evidently is not good for them. I have an XUV and have the radiator almost completely blocked off but neither the red light nor the fan ever comes on. Too much cooling system. It's hard to get it up to operating temp to get the heater to work.

There were, I believe, three bullitens. I don't have them because I got a virus in my computer and had to junk it, so I lost all my prior emails. They all boiled down to condensation, not getting the motor hot enough to burn it off. If you think about it, you are getting water in the oil and you aren't dumping it in there the motor must be making it. The only way a motor can make it is condensation. At least an air cooled motor. I'm sure different conditions ( heat, humidity, driving habits, etc. ) are going to govern how much is in the motor, but I believe it's in every motor. Think about an air cooled motor, It is designed to cool itself under the harshest conditions, right from the moment you start it up, which means it would take a long time to get the head and jug hot. It's not like it has a thermostat in the air flow. So if you have a big temperature difference in the motor, condensation is going to form, and if you don't run it long enough to create heat throughout the motor it won't burn off. If I had your Gator I would block off, or partially block off, the air outlet beside the jug and see if you notice a difference in the water build up, I bet you will. I think that different motor oils have an effect on the amount present too, but I can't tell you which oils are better.

Maybe an easier way is start taping up the flywheel screen and limit the intake.
