190xt oil in exhaust

Is it vented properly? Have seen plugged vent cause a diesel to push oil at turbo. 

Are you sure it's not wet-stacking ?? too much idling time/cold temps ???  Need more fast RPM's and engine load. Common complaint this time of year.

I really don think. This problem came up 2 years ago a month or so after an overhaul. I know it was being used to front feed when it was first noticed. The tractor was basically taken out of service at that point and mostly just sat. I bought it from my father in law for a Christmas gift to my son and got into it again.

I may have jumped the gun some but I ordered a turbo. This tractor already had a cheap aftermarket on it when we got it and it is mostly going to be a project/toy for my son so I ordered another cheap one.

Mine had that problem after I rebuilt the engine a few years ago.  Put it on the cultivator for 6 hours or so and has been good ever since.  You have to put the tractor to work to get the rings to seat.  I would not rule out your turbo either at this point.  Put it to work first though.

I spoke to my father in law about the tractor last night. He says he ground several loads of feed over several months, thinking it may have been a ring break in issue, before parking it. In my mode they are seated. This was my 4th d2800/2900 engine and I’ve had no issue with any of the others. The turbo should be here this weekend but I’m very concerned that there is a deeper issue I just don’t know where to go next if the turbo doesn’t take care of it.

When you get back see if things aren't dried up from wet-stacking. If you've got a load to hook behind it, even better.

I may give that a try after I get some things back together on the tractor. I’m still trying to wrap my head around this being cold stacking. I’ve never had any equipment do that before. I’ve seen this one do this in 40-50deg weather while at pto rpm with the hydraulics running the feed auger and a feed grinder on the pto. Is there anything else that could give the same symptoms?

Funny how more information like 50 degree temperature and actual type of use comes out when you grille people. Turbochargers failing isn't terribly common. I know far more turbo's with 5-6K hrs on them still working fine than those with 500 hrs on them leaking oil. In fact, I can't remember the last time I had a turbo fail period, they are that dependable. I will say there are two good brands of turbo on Allis engines : Air Research and Holset. Anything that is Rajay, Thompson or TRW are a much lesser quality turbo.

There is definatly some oil on both sides, not as much as I would like to see to be certain of a failed turbo though.

My thoughts…
1. What was tractors history while FIL owned it? Used regularly or was unused for extended period? Reason I ask is because you gave engine an overhaul after you got it??
2. When was the last time its fuel tank was emptied/cleaned? Has either your FIL or you ever emptied/cleaned tractor’s fuel tank? I got that you say your home supply fuel tank shouldn’t be pumping any water - ok. But diesel’s return fuel line adds heated fuel back into its cold fuel tank constantly while in operation. That alone over years is an opportunity for condensation to accumulate in tank.
3. Are you certain it oil & not soot diesel/water. A quick smell test can help identify it.

1. He bought it to remove the cab for another tractor. We were told the transmission was bad. After getting it home we found out it was a bad hydraulic pump drive causing no pressure to the power director. After a quick fix we used it to rake hay that summer. That fall it got water in the oil. Then the over haul that winter, ready for spring. Everything was fine for a couple months then the oil in exhaust. Was used to grind every 2-3 weeks until the next spring including a couple trips to another property about a mile away. Oil did not clear up so it was parked for about a year and a half only moving occasionally until I bought it in December.

2. Tank was drained during overhaul but not cleaned.

3. Definitely not water. Seems to be oil to me. Does not have a strong fuel smell and thickens when cold.
