Looking at a 2003 this weekend

[stricker76]

Hey guys. Going to look at a 2003 this weekend with around 110,000 miles on it. Anything in particular I should look at with the engine? I know the obvious stuff with the rest of the truck, but clueless on the Duramax. Going to check the origional purchase date to see if it would still be under warranty for the injectors, but is that transferable? Think i will be the 3rd owner. Any info is appreciated!

See if you can get the VIN before you go to look at it. This way you can have it checked here then you will have some history on the truck.

 

[stricker76]

Wow, didn't know i could do that. Thanks! I'll give him a call and see if i can get it.

 

[Unit453]

LB7's have proven to be good engines over time. I wouldn't be worried about 110k miles at all. Its just getting broken in.

Other than the injectors, they've been good trucks. We have several LB7 owners here so I'm sure they could tell you more from their stand point. I started out with an 04.5 LLY and moved on to an LBZ so my knowledge on the 1st generation is limited.

 

[stricker76]

Can anyone tell me if the injector warranty is transferable? And if there is any easy way to tell if it has injector issues?

Beauty. Thanks!

 

[HemisAreSlow]

I had an lb7...and loved it...just be careful of the injectors...they are not cheap to replace on your own dime

 

[btfarm]

The 7 years is coming up soon so hopefully the injectors were replaced already. I don't know if the replacements were of better quality or not (you would THINK SO). Our LB7 guys should know though.

 

[stricker76]

If i am able to get the VIN and get a check done will that tell me if they have been replaced?

 

[btfarm]

Yes it will.

 

[stricker76]

Well, that one fell through. Going to look at a 2004 this weekend. Higher mileage though, 186000 miles. Kind of worries me, but i guess at least it'll still have warranty for the injectors.

 

[durallymax]

Supposedly if the injectors were replaced after 04 they should have a green dot on the top stating that they are the improved one. I think its a load of crap though. They still go bad.

To do all eight injectors on your own dime in your driveway expect to have about 1300-1400 tied up in it and a good weekends time providing you have good mechanical knowledge.

Im slowly working on getting my step by step writeup finished up. But its taking time.

They really arent that hard to replace. Ive seen good experienced mechanics do them in a regular 8 hour day.

Other than the injectors there really isnt much else to look for that you wouldnt look for in any other vehicle.

Ask the owner if he changes his spin on filter on the trans. Out of all the locals i talk to about 10% of them even know its there. and of those 10% maybe half of them know theres a magnet in there.

you can have the VIN checked on here for a history and if your really picky you can run the truck to a gm dealership and have them scan it to see if it has be reprogrammed recently with any values out of range. This will give you somewhat of an idea if it had a programmer or not.

otherwise they are damn good motors and sound really nice.
