My Boomer 40 was towed to dealership 2/8 after failure and have not heard anything regarding the autopsy results from either sales or service dept...so no update here yet. I will let everyone know what they think may have caused the regen cycle/engine failure as soon as I know for sure.

You would be correct.
DPF burn off is 1100-1200°F. Raw diesel will not clog a DPF but rather it will flow through just like the water does. Actually raw diesel is not injected in the DPF regeneration process. It is injected and ignited right as the exhaust valve is opening where it finishes burning in the DOC/DPF so raw fuel is not actually injected directly into the exhaust.
Close. Hydrolocked due to oil from the turbo would be more likely.
I wouldn't be nervous if you have heated storage.
15w-40 is the culprit. If the tractor is stored in unheated spaces, say below 15°F, the oil is too thick which will starve the turbo and it will grenade itself. Oil will then come out the exhaust, into the intake, or both.
I think all this will come to light as the dealers communicate with customers that have had a turbo go out. I believe you will also see the recommendation for northern climates to use a 0w or 5w oil in the winter.
What would be so special about this one engine that makes it more sensitive to borderline oil, compared to the many other engines that have been used the same way for years? Maybe a newly spec'd turbo?

Dealership responded today. Turbo failed causing one gallon of oil to enter the engine and hydolock it. New turbo and new starter and it's good to go now. Have a feeling this probably aged my engine considerably especially since dipstick had lots of fine metal on it after I added a gallon of oil it had lost. Not sure what my recourse is but for sure I will be sending an oil sample in at next oil change...sure the rod and crank bearings have more wear than 26 hours of use

^^ Might be one of those where it's worth a couple of extra oil changes a few hours apart to help clean it out.

Dealership stated factory fill on New Holland Boomers is 5W40 full syn, guess there is a service message suggesting 0W40 full syn for cold climates. Dealership changed oil and filter and put 5 hours on tractor, will drain and fill oil and submit sample for analysis. They are also changing dpf due to still 30% restricted after three forced regens.

So, my dealer brought another 4155 over Monday morning and took mine back to the shop. Thursday morning he brought mine back with a new turbo. He even threw in my 50 hour service while they were relacing the turbo. Can't say enough about the excellent service and speedy repair. Thanks to Bruce Anderson and Brian, his tech, at Synergy Coop in Ridgeland Wisconsin. Thanks LS for standing behind your product.

I'm willing to bet they meant 15w-40 because 5w-40 should be plenty thin at cold temperatures. I guess I could sample mine to find out.
I was wondering if they were going to change the DPF. That much oil won't burn off quickly if at all.
I know those guys and your right they're good folks.

Service Mgr specifically stated 5W40 full synthetic was factory fill and CNH is now recommending 0W40 for colder climates.

If you haven't driven it a lot since you got it back, if the dealer didn't run it a lot and, most importantly, if you like this motor......... Consider flushing out the block and oil passages.
On race-cars, if we grenaded a cam, or anything else in the old, old days (Chevy's are bad for that) we'd pull the valve cover and the oil pan and pour some mineral spirits through it. A Gallon or thereabouts. Wait until you're ready (at least an hour) and fill it with oil, give it a new filter, start it and then drain and fill it with fresh oil and give another new filter after a half-hour of run time.. Sounds like a lot but, in our defense, oil was about a $1 a quart and we had 55 gallon drums of it. YMMV
Might be a waste of time and money but..................
Maybe the Dealer flushed it out really well. I would hope he did. Wouldn't hurt to ask.

Wow. Just wow.
So if I'm reading this correctly, it has nothing to do with regen, but rather cold start initial operation with the wrong cold viscosity oil. ****, I was hoping 5W-40 syn would be enough. I better be careful.
Next question: "Partially" failed turbo seal = oil consumption and/or more frequent regen's?
Diagnosis would be to remove and inspect I spose, since the DPF won't allow it to belch smoke at startup?

Based on diagnosis dealer gave me I'm guessing turbo contaminated dpf causing regen cycle to clear dpf. Surmising regen was result of turbo failure not the cause. New dpf due in this week so hopefully I'll have tractor back by weekend. Still very concerned about an engine with 5.3 qt oil capacity with filter being 4 quarts liw on oil in 15 minutes����

Hope you get your tractor back and in great condition.
It doesn't get nowhere near as cold here as you guys get or Canada but I still plug up my oil pan heater if I plan on using the tractor on cold days.
I only use an oil pan heater, not a block coolant heater, I had prefer my oil be warm and flowing right from startup.
I still let her idle a bit before I actually start working it.

Well new DPF arrived at dealer today, hopefully will have my Boomer back for the weekend. Dealer sent me the New Holland service bulletin that describes to a "T" exactly what happened to my tractor. MTron equipped tractors built after 7/3/2018 have factory fill 5W40, ones built before have 10W30. Tractors built after 8-8-2018 have a software strategy that limits cold idle rpms to protect turbo during warmup. If you have an LS or New Holland 1.9 MTron tractor built before 8-18-2018 be sure to change to 0W40 full syn and contact your dealer regarding software update. New Holland bulletin (knowledge Article) KA000001894 dated 10-31-2018. Hope this helps save someone the trouble I had to experience...if I had know about this issue I would have addressed it before the winter season.
This is NH's software update. I wonder if the LS software is the same and if they are driving this or if they will handle their issue with a separate solution.
