| I have this engine in a spreader truck and it has water in the oil. I assume that the engine needs reworking. What are your thoughts? How big of a job is it to build this engine? I have never rebuilt one before however, I do most of my own mechanic work. |

East central Indiana | It's just the oil cooler on that motor. Currently overhauling one of our own in a spreader truck. Parts are cheap and these motors are easy to work on. Don't run that much or you'll be in our boat where the pistons will self destruct. I don't know why but 466s seem to be bad about blowing oil coolers. |

Iowa | check oil cooler first |

West Central Iowa | Water or coolant in the oil is most likely either a pin hole in a liner or liner o-rings leaking. Now oil in the coolant would most likely be a bad oil cooler. |

| It has coolant in the oil. |

Faunsdale, AL | Just got through repairing one with a pinhole eroded in the aluminum plate behind the water pump. Had recently done an inframe overhaul, so that really was discouraging.
Oil coolers are easy to check or at least easier than anything else, but usually have a radiator full of oil unless it drained into the oilpan while sitting. Had an 855 that did that. Figured it had to be a sleeve or o - ring,. Overhauled it .......and then replaced the oil cooler when it put oil in the radiator after we started it up.:-/
They don't all read the book!

Eastern North Carolina | Pull the oil pan and pressure test the cooling system before you go any further, look from underneath and you can probably see where it's coming from. Does this engine have a coolant filter, if not it's money well spent to add one.

Boone, Iowa | I agree with pirlbeck. Drop the pan and pressure test the cooling system. You may have to turn the engine over a few times to figure out where the water is coming from. Could be an o-ring on the sleeve, pinhole in the sleeve from electrolysis. I have seen injector tubes leak coolant into the oil. Don't rule out a bad head gasket, but I would lean towards an issue with a sleeve. |

| Agree with retento . Oil cooler puts oil in the water . Oil pressure is higher than water press . Drop pan and pressure radiator . Look under and ul see it . Doubt u even have 2 pressure it . If water comes outside sleeve its orings . Inside no doubt a hole in sleeve . Maybe injector sleeve . |

| I will check it further tomorrow. If its a hole in the sleeve or o ring how much does a kit usually cost and will it take any special tools. |

Hazelton, Kansas | Drfarm,
What I'm about to say is NOT NAT approved, but falls into the "what do you have to lose?" category.
I had an otherwise good running old 466 in a SA tractor. '86 vintage, so even with new tires, it would probably hurry it to bring $2k at an auction. Money maker, in other words. It started losing about 2 qts of coolant a day, pulling 8 or so trips to town per day during harvest. Valve cover and dipstick showed lots of condensation, so I assumed it was the o-rings at the bottom of the sleeves. Didn't check the cooler.
On Dirtpoor's recommendation, I pulled the top radiator hose, threw in two bottles of regular old Bars leak, refilled the rad, and drove it like I stole it for about 30 minutes. Then changed the oil and filter, and repeated the oil change a couple of days later.
It's now two years later, and the engine still doesn't use oil and drives as good as ever. Condensation and coolant loss are gone.
Having said this, it will probably have 2 gallons of coolant in the pan when I start it this spring.
This is not an endorsement or recommendation...just a story.
FWIW

NC IA | I agree with jedeka and pirlbeck. Those engines are notorious for sleeve cavitation/o-ring issues. But in defense of the oil cooler guys, I've seen a oil cooler bad enough to get coolant in the oil, once (on an IH 466.) But it had been pumping oil into the coolant also, for a long time prior. Pull the pan, and put 12 psi to the coolant system, I'll put a 90% chance you will see drips coming from a sleeve. |

Elmwood, Ne. Just East of Lincoln | I would bet on O rings. I had water in the oil on a 2003 DT466. It was O rings around the sleave that let go all at once. After checking into it after the fact, I found out IH had trouble with these O rings in the early 2000's. Wound up with an inframe overhaul at 160,000 miles. |

Texas/New Mexico Stateline | I would think an aftermarket in-frame kit would run less than $2000. Pistons, sleeves, bearings and gaskets. Probably not AgTalk approved, to not do more than that, but I had a 1086 IH which has a very similar engine and it was $1500 for a Federal Mogul in frame kit. It did not require any special tools at all. Other than a torque wrench and ring compressor. But I did nothing to the head other than clean it up. Even left the injectors in. Runs like a top now.
It had the same deal. Coolant in oil and it was a sleeve leaking.

| Just did one in a 1480 this summer, was O ring. Rebuild kit about 1200$ from agkits .com fairly straight forward. For the price of a kit it's worth it.

Almond Wisconsin | Dt 466 is the easiest inframe there is. I have done many in my farm shop. Definatly do the pan drop pressure test and see which hole is leaking. If it is pushing out on the outside of the liner you can get buy pulling it down changing rods and mains, new O-rings on all liners and go. Just push liner out from below and leave piston in bore. Make sure to inspect cam lobes and outside of liners for cavitation. If liners show any flaws change out the whole set and get the head done. But if the unit doesn't get alot of miles and is running good you could get by on the cheap. Better put my flame proof undies on because I'm sure it would not be NAT approved! |

n.c.iowa | got a buddy that does this type of repair all the time, one lucky dude,he got payback though recently,a neighbor had a 1486 he wanted overhauled,bought from origins unknown.it had three different types of pistons in it,"a" and "b"series rods,and the cam looked like they built some of the lobes up with a welder and ground them with some type of hand grinder. |

Eastern Washington State | I'll put that to 99% chance. Guaranteed. Well.....except for the 1% chance that it's not. |
