My recent barn find… you guys like trucks, right?
 

03 Silverado 2500HD Duramax 37k original miles. Original owner bought it after retiring from GM to pull his camper. After 5 years things in his life changed and he stored it in his barn only taking it out to run to store once in a while. He kept a Very meticulous maintenance schedule and gave me a detailed print out.

Anyway, going to make a few improvements and use it for my Home Depot runs!

Nice find!!

SCORE!! Congrats

Looks really nice.

Amazing find! Beautiful truck.

Not trying to be Debbie Downer but is that one of the years that the Duramax had injector issues/extended warranty TSB? Did you get the service records on it?

Appreciate the comment. Yep well aware of it. unfortunately the guy I bought it from did not have any issues with them and therefore they weren’t replaced and of course the time is expired. After reading a lot about them, there are many people who got hundreds of thousands of miles out of them with proper care. One of the things that I’m addressing is putting a lift pump in to help and obviously supplementing my diesel fuel. It will most likely get light use so I’ll drive until I see any issues.
I’m really digging it! Unlike my new one it doesn’t have all the emission junk on it and I love the smell of diesel!!

Very cool!!!

I've been using the Optilube XPD religiously for 15+ years now in our 1995 6.5 K2500 Suburban. Best-rated lubricity enhancer out there. I know the Duramax'es are a lot different than the old 6.5 but I replace my lift pump every couple years. I bought a Napa (Carter) pump years ago that had a lifetime warranty and the moment I think the pressure output is slipping, I bring that baby back into Napa and get a brand new on on the house!

I have been running hotshots secret EDT (everyday diesel treatment) in all of our farm equipment and pickups. My brother in law didnt and put $9000 in his F250 last year when it ate its pump.
Hotshots is ran in a lot of diesel prostock tractors making over 3000 hp and it is made here in Ohio. Seems to be good stuff

Appreciate the advice. I have tried others but I’ll look that up. You just follow the amounts indicated?

I'd do the lift pump first since the truck probably hasn't had it ever replaced. I was on rockauto and it looks just like the 6.5 lift pumps in my '95 but with a different fitting/harness connection. It's as easy as replacing a canister fuel filter. It's hanging on the frame rail midway between the bed and the cab. A properly functioning lift pump takes a ton of stress off the rest of the injection system. Check out Napa, first and see if they still have the lifetime warranty on their lift pumps.

So that’s just it and part of the injector issue is GM DID NOT install a lift pump in this Dmax version. They just have a CP3 fuel pump which is sucking fuel a long ways. This compounds the issues with the injectors .

The aftermarket offers external options, these come with extra filter and water separators designed to assist and clean fuel. There is also an internal fuel tank pump as in option , but this offers no additional external filtration. Depending on the “expert” you talk to gives pros and cons to each.
Everyone does agree that is a must have addition so I’m down the proverbial rabbit hole. If anyone has real world experience please do tell.
Truck runs great, I enjoy driving it.

Very interesting! You're telling me that the 6.5 engineers actually had ONE thing they did right? :wink:
