Grenanded the engine in my 2015 3500 w/Aisin

[Newsa]

Have you tried to bump the starter to see if the engine is locked up? I wonder what the computer was thinking?

Nick

It was running on motor oil, not diesel?????

Yeah. I'm sure the computer couldn't do anything.

 

[Newsa]

IMHO this is not a warranty claim but an insurance claim! No way would I pay if I were Chrysler.

I disagree. I think Chrysler will take at least partial responsibility since they didn't foresee that happening. They Don't test at those angles, but I think they want to check out this and they will buy the truck back.

Well.....when I replied to the original poster over on CF, based on his description of the issue, it had runaway written all over it. Until the adjuster checks it out---it really is only speculation at this juncture.

Yes. I think Cummins/FCA want to study it in case of future roll overs?

I can't imagine a better guess as to what happened.

How do you know this???

He doesn't

Excavators are designed to run at extreme angles, up to 30 degrees. Which means the engine must also be able to operate as such. There may be a few differences in a truck application but I guarantee you Cummins knows exactly what angle their engines can be run at.

Most GM Diesels had the emergency block off valve on the intake, if they were still hooked up.

Had a few 71 series engines that would just keep running after the emergency air shut down was tripped on one engine a 8-71 it wouldn't even slow down. Once you have a diesel ingesting it's own lube oil the only way to stop it is to cut off the air. My uncle told me of being on a diesel sub and they had been running the engines really hard and they would run away. He said they had made these metal plates to choke off the air intake and save the main engine.He was one for telling tall tails so I never really believed him....

My first gen had a run away shutdown lever on it. Second gen and up I no longer see them.

Any more info on this mr. Original poster?

"They Don't test at those angles"

You got me. I just assumed they Don't test at angles that are greater than typical back mountain roads. They probably wouldn't test at an angle where the oil pick up tube Doesn't pick up oil... which I imagine is a large angle of incline/decline.

So I shouldn't have said what I Don't know.

I also Don't know if his Cummins was tuned. Because if the tune caused the problem, I would think it's not covered under warranty

I remember a generation of Cummins back around 2006 that had a problem with pumping its crankcase near empty when descending steep hills. They came out with a retrofit kit to stop it from happening. So it’s not unheard of.

That shut down leaver only turned off the fuel. If you've got lube oil getting into the cylinder shutting off the fuel will do nothing to stop it. Hence the run away issue. Only way to stop then from running away is kill the air going into the engine. If you've got a big enough C02 fire extinguisher dump it in the intake and follow it with some rags to choke the engine.

I wonder if Chrysler has already had this gent sign a non disclosure agreement?

Much farther back than that

Since it happened on a Saturday and Monday was a Holiday (maybe) I suspect he's just now going through the processes to figure what happened. But I agree, if FCA takes any responsibility they would prefer a non-disclosure agreement.

 

[seafish]

You guys, there will be no non disclosure agreement nor settlement or lawsuit with FCA over this.



In point of fact, while driving, the OP accidently slid off a steep icy road and ended up off the road and sidehill on an even much steeper 42 degree embankment. Eventually the truck got pulled around facing uphill with the engine running on the same steep embankment and then it seems as if the engine ingested oil or oil fumes and ran away.

There were also some parts found left underneath the truck after it got pulled out.

How is ANY of that FCA's fault or responsibility??


Unless new info comes out that indicates otherwise, this is an unfortunate but pretty simple case of user error.

Hopefully his Comprehensive insurance will cover the engine damage.

I’m just here for an interesting read but I have to wonder why one wouldn’t shut their truck off if they just took a plunge like that and was resting at an extreme angle?

Don't really know that either...going to have to go with "user error" again, though I am sure that he had a reason!!

 

[Learjet]

What about the throttle butterfly we have? would that not shut off the air?

 

[bob53magnum]

Lots of luck with the warranty.
