breather pipe

The breather pipe ( the one next to the engine oil filler) has a mayonase quality looking liquid dripping out of it. Not much though. Also when i check the gear oil, the oil on the dip stick is the same color.( Yellowish)

Is this normal. When I check engine oil it is fairly clean on the dip stick.
 
Yes, that is water. Is it normal? Depends...

The milky deposits on the engine breather could be condensation. That will occur if the engine has been
started and stopped, allowed to cool, and not brought up to temp repeatedly. It can also be caused by a
missing or stuck open thermostat. The first thing to determine, is the thermostat working? Keep a close
watch on the coolant, and put some hours on the engine, preferably with a load, see if it will dry up on
it's own.

Another cause can be a leaking head gasket, or leaking orings at the bottom of the cylinder liners. Typical
symptoms of head gasket problems are mysterious loss of coolant, overheating and blowing coolant out the
overflow, misfire, steam out the exhaust.

Leaking orings are harder to diagnose. They will quietly leak coolant into the oil with no other symptoms
other than the milky froth on the breather tube, and mystery coolant loss in extreme cases. Sometimes stop
leak will seal them.

Water in the transmission is very common on these tractors, especially if stored outside. It condenses
inside the case, and also gets in around the shifter boots and the top link boot under the seat. Be sure
all the boots are tight and not torn, rotten. Drain the oil, let it sit with the drain plugs out until it
stops dripping. It can also be flushed with a couple gallons of diesel, start it up, cycle the lift to
flush the hydraulics, drain the flush, refill with 8 gallons of 15w40 engine oil.
 
You are in northern New York right? This time of year the dew is into everything, all oils look like coffee and creamer unless you got a heated garage. Who does eh?
Don't worry about it yet. When I lived up there I would check the oil at noon, it was already steaming? evaporating? the water out, and looking different. By the time I tied up at night, the oil looked like oil again. Next morning, same $%^& different day!
 
Amount of oil depends on which tractor he has. The 35 takes 8 gallons, the 30 takes 6 gallons. I'm not sure he said what he has?
 
Steve you hit it right on the head. I ran it yesterday under load and it did dry out.. Everything is great.. I thought I had a blown head gasket.. I was starting it a few times when I first bought it a few weeks ago just to check for leaks and I guess that was the problem. And yes Tony Im in upstate NY and your right about the dew.. Thanks again guys.
