Diesel Truck Shiat - Per Cook's Request...

[Sharpe]

i dont care to own a new truck, so i dont know. but whats with the urea injection? what would happen if you dont use it?

It is squirted into the exhaust to chemically clean it up before exiting. If you run the tank empty, trucks that use it now go into limp home mode. The O'Reillys rep was telling me about it this morning. He said that most medium duty and heavy trucks currently using it consume about 2 gallons of the urea **** for every 100 gallons of fuel. Not too bad price wise but remembering to top it off would probably be a PITA.

too bad they don't have scratch and sniff screens, you of all people would be able to tell us if it was burnt or not!

it was just glazed? I thought it failed catastrophically (or as I prefer to say, spectacularly!)

[AggieTJ2007]

yeah on GM you should only need to fill up the urea every oil change. it if gets low it will annoy the piss out of you and if it goes empty the truck goes into limp mode and you are limited to 5mph.

I bet it would be interesting if you dumped gas or diesel in the urea tank and could shoot flames out the exhuast

Is there something wrong with it?

Check out all the clutch dust/reminants in the center of the flywheel and clutch forks. There isn't much left of the ceramic/feramic disk once you see it in person...

However, if some diesel wanker wants to slap it in their dodge go right ahead, it has been riding in the bed of my truck for a couple months.

I don't doubt that it will be one of the first things EFI Live works on for the new engines. It will be the same as the DPF or EGR, in just a few minutes you will be able to edit it out.

[AggieTJ2007]

yep and then the guys will be using the tank for water methanol injection, or at least that is what they have been talking about

Alright so...might be going to look at some Duramaxes this weekend. 2004 and 2005 models, most of them right around 100k miles.

In addition to the stuff posted up by people to check out on the 03-07 Chevys in Cody's Box...what Duramax specific issues are there to look out for? Never owned or spent much time behind the wheel of a Duramax...

And I already read the old Duramax threads/posts on here.

Something that pisses me off about mine is some of the lights on the radio are burned out, but that is more of something that pisses me off. It sucked the first time I drove it in the dark.

What engine do I have? Check the 8th digit of your VIN number- LB7=1, LLY=2, LBZ=D

2001-2004: LB7
Injectors. Make sure the TSB has been taken care of.

2004.5-2005: LLY
FAQ for the LLY

Both of these come w/ the 5 speed Allison. Good transmission, but if you plan to put any really hot tuners on the engine it will need help. The 'fix' for this is not near as cheap as it is in the 6speeds. If you plan to run it stock and not Rowdy it out, it will be just fine with regular filter/oil changes.

The 04.5 LLY was the first one to come w/ the VVT (variable vane turbo) which helps in building the boost faster. I believe they also will have the grade/turbo brake in Tow/Haul mode. You can get an aftermarket one that will really bump up the effectiveness on this, and it makes a ton of difference and well worth it.

I'm a diesel fag now. Yay?

[Seth]

good deal?

[TexTJ209]

5k off KBB value, so I'd say yes.

Costs me about $50 less a month than my old truck, and gets about 7 more mpg so far. Plus it has a back seat and 4x4, whereas my old truck didn't.

Nice

[Shaggy]

I dig it

[DRAGOONRANCH]

What year model? We'll get you headed down the 'dieselfag' path right, quick and in a hurry w/ an EFI tune (or 5)
