Mine did it once because of bad fuel. Unfortunately it is hard to diagnose stuff over the AOL.
Someone was describing a noise their car was making to me and I advised them to get a brake job....... He needed a new serpentine belt

Best bet is to figure out some way to get your hands on a dealership computer. Those things show EVERYTHING.

Personally I wouldn't go to TNT, but you have to do what you have to do...
When was the last time you changed your fuel filter...I would start there.
go to TheTruckStop.us create an account and go to the LMM section and ask your questions...we have an expert mechanic goes by TheFermanator that will give you excellent advice

I've been hoping you would show up.
Fuel filter was changed a couple months ago.
What's wrong with TNT? I have no experience with them besides what I've read online. I'm open to suggestions for sure.

I'm an LB7 guy but my good friend knows all of these Duramax' in and out and will help you get a proper diagnosis...He can't actually turn wrenches for you because he lives in Zephyrhills, Fl...
just go to that link and we'll get you on the right path...

only thing close to the water pump on my truck is the cam sensor and crank sensor plugs
don't think it would run if completely unplugged...not sure what it would do if just barely making contact...

I don't think anybody can predict that

Who knows? It is such a PITA to work on them now because the engine compartment is completely stuffed. Could've put his foot or rested his elbow on something

I opened the hood of a 6.7 ford a few weeks ago
Some MAJOR engineering went into just fitting all that shite in there.

I'm still thinking fuel filter or maybe bad fuel...when was your last fuel stop?
different fuel station maybe?

When my engine is in the truck, the turbos are underneath the cowl. Hell 1/8 of the whole engine if behind the line of the firewall

Have you looked into the 6.7 induction system?
Pretty damn cool. The reverse flow heads with the turbo in the valley is cool as hell.

Fuel filter is not very old. I typically only buy fuel at one place so I don't think it is that either.

Never say never...If your fuel filters weren't $35 I'd change it just for the hell of it...but then again, your going to pay a mechanic more than that to diagnose the truck...so I'd still recommend changing it...
I don't have the factory fuel filter manager anymore...when we did this build, we eliminated it and went with an Airdog165...I always ran a huge 2 micron Cat filter as a pre filter though...now with the airdog it has 2 filters already...

The valley on most engines is actually pretty cool as far as engine temps go.
On gas burner carb motors you can make carb spacers out of wood with no problems.
It's much cooler there than it is by the side of the block on a gas burner. I don't imagine a diesel would be much different.
Of course with the reverse flow heads your exhaust is in the valley so it's probably a good bit different. I'm sure the temp of the turbo is so much higher than everything else around it that it really doesn't matter though.

GM started that with the baby dmax they were going to introduce in the 1500 series a few years ago...it really is an efficient set up
regarding extra heat in the valley...Turbo's and pedestals are there already on most v8 diesels anyway...
which reminds me...I keep forgetting to buy a damn turbo sock... been needing one for well over a year now...

That doesn't overheat the turbo and cook oil?

not really...it helps the turbo retain heat and spool faster...also keeps your under hood air temps down...no intake is perfect so hot under hood air will make it's way into the intake which will rob some power...
