WATER IN OIL

doubledollar · May 17, 2016

I HAVE A INTERNATIONAL 986 THAT IS GETTING WATER IN THE OIL BUT ONLY AFTER THE TRACTOR SITS UP FOR A WHILE. AS LONG AS THE TRACTOR IS RUNNING ALL IS FINE, ITS NEVER GOT HOT AND RUNS GREAT, JUST HAS A SLOW LEAK OF WATER IN OIL AFTER IT SHUT DOWN. FYI, I HAVE REPLACED THE OIL COOLER AND I ONLY HAVE ABOUT 3000 HOURS SINCE THE LAST OVERHAUL. HELP PLEASE !!!!

I had one doing that a few years ago, and I finally rebuilt it.

Could be bottom of a sleeve o-ring but get on the International forum and ask.

Try some Bar's stop leak.

When it is running and hot, you may evaporating the water from the oil. Are you running straight water or antifreeze mix?

Assuming by "water" you intend "coolant" ? Better to trouble shoot instead of just guessing and replacing good parts then still having the same problem.
There is a tool to apply 15 psi to the cooling system with the engine shutdown to find leaks.
Applying air pressure with the cooling system full then later moth while looking and listening for leaks is quick, low cost and non destructive .
Pulling the oil pan maybe required to locate leaking sleeves.

A bad oil cooler will almost always put oil into the cooling system before coolant gets into the oil. With the engine running you will have 40 - 60 psi of oil pressure working against 15 psi in the cooling system. With the engine of the pressures reverse. You will now have 15 psi in the cooling system and nothing in the oil side. Coolant can then enter the lube system.

Those engines use three O-rings on the bottom of the sleeves. Only the top one seals between the crankcase and the cooling system. The lower two serve to locate the sleeve in the engine block. The top O-ring groove in the sleeve is not as deep as the other two. The top O-ring seals against the chamfer at the top of the lower cylinder bore. If that sealing surface has suffered any erosion the O-ring will have problems keeping a good seal. Because the bottom of the sleeve is located by the two lower O-rings it can move around a tiny bit but that little bit of movement is enough to keep cooling system sealants from working very well.
