I saw a video the other day thats been going around on Instagram, of a single cab newer Duramax running away and I got to thinking..... That is the 5th video I've seen of a duramax running away and blowing itself up in the last 6 months or so and I havent seen a Cummins (unless someone was tuning a VE) or a PowerJoke run away and grenade itself. Is this starting to be a common problem with them? Are the Borg Warners that they use a bad turbo? What do you guys think? I just see it as another reason to NOT buy one and another vehicle to Cummins swap. 

But are you really worried so much about your pickup running away that you'd spend $800 on something you would most likely never use?  Just check your turbo for leaks every once in a while and you'll be fine.

Better to have it when it happens rather when you're standing outside watching your pride and joy blow up. If it comes down to it and it saves my $2k+ motor, I think its worth it.

I've had a turbo leaking oil so bad it blew boots off at 5 psi, and never had the pickup even think about running away when I shut it off.  If it's not gonna run away then, probably the only time it would, would be if you had excessive crank case pressure and worn rings.  But by then your $2k motor is toast anyways so.

For $700 I think I'll opt for the nice PacBrake one thats only $100 more and a lot cleaner.

 

Won't have to worry about that, our '12 is getting a full delete soon!

Deleted is the only way to go. Won't fix the fuel system but will definitely prevent catastrophic engine failure.

Yeah you're right.

Delete and HP tuned by yours truly 

So having an oil shut off valve on the oil line to the turbo won't work on our 24 valve 2nd gens?

Probably would, but then you'll be out a turbo, but if you're willing to make that sacrifice then more power to you!

Thanks Great White, well... if the turbo bad enough to leak it may not matter. Then again, no oil means it may throw bearing pieces in the intake. Is that what you mean?

I don't think it's a common enough occurrence to worry about, and if it does happen put it gear and slam on the brakes :-)

Yeah, but from what I've heard, and take this with a grain of salt, but I think Holsets are self contained and if they do go they won't send fragments, but I'm not sure on that, just is what I've heard. But yes if you wanna just sieze it that's a good option. Never thought that if it was that bad might as let it die. Another excuse to go bigger!

That is absolutely not true.  Holsets will throw shrapnel if they let go.  Starving a turbo of oil to seize it is also a bad idea.

Oh my bad, I was just relaying what I had heard, and that's what I was thinking I'd rather starve the air.

Here's a little video of the Detroit DD15 first start after the complete out of frame rebuild. This is where those injectors I posted came from. It's got all the emissions controls. DPF, EGR, and SCR using DEF.

What is SCR?

Selective Catalyst Reduction. Uses DEF for a chemical reaction to reduce NOx output. SCR and DEF was mandatory with EPA13 emissions regulations for diesel engines. Probably didn't see it until late 2013 or early 2014 Ram trucks with Cummins engines. Emissions go by year of engine and not year of truck for diesel engines which is why you see glider kits so popular with OTR drivers. A glider is sold without an engine or transmission then you install the power train of your choice.

I don't know what a glider is but I'mma just nod my head and say ok

Freightliner, Kenworth, and Peterbilt all sell what is called a glider kit. A glider is a cab and chassis built anyway you'd like it without the engine, transmission, and differentials. You then can install any engine, transmission, and differentials you want even if said engine is a mechanical Cummins from 30 years ago. You have a brand new luxurious truck without all the wallet draining emissions bologna. Unfortunately glider kits are only available to the class 8 rigs.

I find that kinda interesting that you could buy, say, an N14 on a glider kit like you're describing.

Yep. Gliders are quite popular with the guys that don't haul freight in California. CARB frowns upon gliders.
