I help out on my mother-in-law's farm, as well as my own, she has a older 180 AC, (her dad's), it failed to start, and had a antifreeze leak that I could not find. while I check the oil, I noticed that the oil was gray in color, a older farmer, said that means there is water in the oil, and that needs a complete rebuild. just checking my great resources here, to see if it is worth it, what it would cost? and even if that is the case. I never did find the water leak, so I am assumming it is indeed leaking into the engine..

YOUR 180 AC TRACTOR HAS O-RINGS ON THE BOTTOM OF THE SLEEVES. THESE O-RINGS HAVE A TENDENCY TO ROT OUT IN TIME. ESPECIALLY IF THE ANTIFREEZE HAS NOT BEEN CHANGED REGULARLY, OR THE TRACTOR SITS FOR LONG PERIODS OF TIME. YOU WILL HAVE TO OVERHAUL YOUR TRACTOR TO REPAIR THE PROBLEM YOU SHOULD TAKE THE ENGINE COMPLETLY APART AND CLEAN IT. HAVE YOUR MECHANIC CHECK THE BOTTOM SEAL LAND OF THE BLOCK IT MUST BE CLEANED VERY GOOD. THE ENGINE KIT WILL COST YOU ABOUT A $1000. PLUS LABOR. THE TRACTOR IS WORTH THE PRICE OF AN OVERHAUL, AS LONG AS YOU DON'T HAVE A BUNCH OF OTHER PROBLEMS

Thanks all for your help, we will have it overhauled, I have never done a engine myself, so I will have a local dealer do it, if it was my tractor, AC 6060, I would probably do it myself, but since it is heres, and time involved is a issue as well. we have been quoted @ $4000, to do a complete overhaul.

We use a 180 AC on the farm quite a bit. It is a good running tractor. The only problem we have ever had is it seems about every ten years we have to replace the cylinder sleeves because they seem to rust through from the water/antifreeze side until a pin hole develops. I would go ahead with a cooling system pressure test.

pitting of the sleeves from the water side on a diesel engine is not uncommon. some manufacturers install a water conditioner to the system. this can be in the form of a spin on canister (like an oil filter) or a bag of solid crystals that you dump in the radiator once a year. Allis construction division used both in the mid 1970's on their diesel engines.

The cooling system additive that virtually eliminates liner erosion is called either SCA (supplemental coolant additive) , or DCA (diesel coolant additive), depending on manufacturer. NAPA also sells this product, but unsure of their product name. If you have a Baldwin filter dealer near you, they go by the DCA 4 name. JD engines seem to be very prone to this type of damage, too. Most all diesel service dealers (authorized cummins or dda dealers) will carry this product.

If your only using the tractor occasionally it could be condensation in the engine causing the milky appearance in the oil. Before you start tearing it apart looking for a leak, you could get a local mechanic who has a cooling system pressure tester to use in on you tractor. This way you could eliminate any external leaks, and it would help show which cylinder on the head gasket or cylinder are leaking. Just a hint because ive found some water pumps leaking occassionally at certain pressures under load, that you couldn't find without the tester.

Joe,
It sounds like there's a problem with either a head gasket or a sleeve seal leaking into the oil. The head gasket shouldn't be too hard to fix, but a sleeve seal will be tougher, as the engine will have to be disassembled farther to fix the problem. I doubt that the engine has been harmed to the point of needing a complete overhaul, but tearing it down is the only sure way to find out.
You might try replacing the head gasket first and see if the coolant leak stops. If the engine doesen't make any bad noises, you're ok.
If the leak continues after replacing the head gasket, pull the pan and see if you can see coolant dripping from the bottom of one or more cylinders. If you do, those cylinder sleeves will have to be pulled and the seal replaced at the bottom.
A third possibility is a freeze crack somewhere in the engine allowing coolant into the oil.
A fourth possibility is a rusted out freeze plug leaking internally.
I don't know enough about the 180 engine to give much more info than that.
Good luck, and I hope it's the easiest and least expensive fix.

Phil

Thanks,, the engine doesn't make any noises, (other thans standard diesel noises), and in fact it ran better than my 6060, starts a whole lot better!, I will replace the head gasket and see what happens...

If you see one liner leaking from the bottom with the oil pan off, don't stop at replacing just one seal pack or liner, if one is bad, the rest can't be far behind.
