1086 ANTIFREEZE IN OIL

Anonymous-0 · Dec 22, 2013

I have a 1976 international 1086. Has about 6500 hours on it. Went to check the oil today and I noticed it was two inches above the full mark. when I pulled the oil drain plug about a cup of straight antifreeze came out and the rest of oil was a gray color. Obviously i have a big problem on my hands. Need some advice on where to start. My thought is to pull the head and go from there.any other thoughts?

Probably better to pull the oil pan and look UP... probably he most likely problem that would occur while sitting would be pitted sleeve(s).

You should be able to see where the coolant is coming from.

Another idea would be to pull the injectors and crank it over. If a LOT of water comes out of a cylinder, that might point to head gasket or head problems.

Like Bob said, pull the pan first. Probably a sleeve rotted out.

Could be the oil cooler, or a head/gasket issue as well.

I'd bet just about anything that you have a hole in a sleeve. My 886 did almost the same thing a few years back. I serviced it all up, including oil and filter change, so it would be ready for haying. Parked it in the shed and went on a three day fishing trip. Came home ready to hit haying, checked oil out of habit, and she was full to the top of the dipstick with antifreeze. Sleeve gave out just sitting in the shed. So........an engine overhaul...........and then we hit haying

Yep,

Sleeve or O-ring.

As others stated probably a sleeve or oil cooler. Is there any oil in the radiator? Oil cooler will put anti freeze in the oil while sitting but when running the oil pressure will push oil into the cooling system. Makes for a real mess to clean up but cheaper than an overhaul. Drop the pan an see if you can see where it is coming from. Sometimes pressurizing the cooling system helps to find the leak.

When did the 86 series come out? My 10 is fairly early, it's the first 86 I ever saw. Anyway, it cavitated a sleeve at 6600 hrs. pulling under the scale in the feedhouse. The way I understand it, the early 86's did not have a coolant filter and suffered more failed sleeves. Just wondering if yours has a filter, mine doesn't. I mean didn't!

I would pull the oil pan off then fill the cooling system and pressure test it. See where the coolant may becoming from.

My 1086 had mildly pitted sleeves both times I overhauled it (5000 hrs and 10000 hrs) and it does have an anti-freeze filter that's changed regularly. Jim

Several years ago I had a late 66 series that did the same thing. I replaced the O rings in the oil cooler and that solved the problem. A $3.00 fix. Its a cheep place to start. Bandit

Check the oil cooler first! We have experienced this several times on 86 and 66 series tractors. A neighbor overhauled his 986 just to find out it was still getting coolant in the oil. New O-rings in the cooler to solve the problem.

As others said, pull the pan first, fill with coolant and look up and see whats leaking. You can't tell much pulling the head. Also the pan is the easiest thing to pull off !! Mark
