coolant in oil

Hello to all.
I have a Cockshutt 1800,6cyl 283 gas tractor that has developed a coolant leak into the oil.The oil is milky looking.I changed oil and filter,and within approx. an hourI checked it again,guess what, milky oil.Parked tractor in the shed over night and drained oil the next day.Thought by sitting overnight coolant and oil may seperate,however when we drained it we didn't notice anycoolant draining out before the oil.We dropped the pan and pressurized the system to about 15 lbs.which is more than likely double what the normal would be,and can see nothing dripping from around the sleeves.By the way,this engine when running,runsgood,smooth and there's no white smoke like you may expect if it was leaking from the top end.I'm kinda scratching my head now wondering where to go next.Any ideas or suggestions would be helpful.Thanks in advance.
 
We have an 1850 gas 310 and a 880 gas 283 that have milky looking oil all the time. I think it must just be a wakasha thing. The 880 we have had for years, never needs any water but oil is milky. The bottom side of the dipstick cap looks like half melted ice cream most of the time. Usually it is worse looking when you are using the tractor in the winter a lot. I can not figure out why they do this but they do. Just to be safe on yours I would drain oil rence out tank with diesel then put plug in and let tractor sit for week or 2 then take plug out holding a clean pan under it and see what you get.
 
I have an MM UTU that does that. First determine if it's water or coolant. Mine is simply condensation not getting burned out because it doesn't have a thermostat.
 
never tried before in an engine but peppermint is used to find plumbing leaks. doesn't take much...put in the cooling system...if it gets in the oil you should smell it
 
What king of oil do you use? We run valvoline conventional in all of our gas tractors. Pennzoil kind of has a reputation of leaving a chalky white film.
 
Thank you for your comments We've used Co-op oil 10/40 in the tractor for years.The tractor used to be used for actual farm field work,where it would get warm enough to burn off any moisture in the engine.Now its kinda semi retired,and is just used for haying.Maybe it doesn't get hot enough to get rid of any condensation in the engine.What I'm going to do is change oil and filter,start it up hook up to our cultivator and do our trees and then I guess I'll wait and see what happens.
 
Thanks for you reply.I never really had considered condensation,but will check out that possibility.Im going to change oil and filter,fire it up and make it do some work and warm up he engine and see what happens.
 
Thanks for you reply.The 1800 does have a thermostat,but is only used for light work(haying).I'm going to check out the condensation angle and see what happens.
