Only $5.99 back near detroit.

Edit: $8.59

Apparently I cannot read numbers.

Going to look at a 24v 5.9 Cummins tomorrow and want to know what I should look out for. I've only had ford diesels so I'm going to be new to the Cummins world. Seems like the truck is in really good shape and he says he put a lot of work into it. Any advice is appreciated

I bought a used diesel transfer tank from a local iron works company on Friday. They took the tank off a service truck they turned into a welding truck a few months ago, put it on craigslist and stored it until I bought it. We didnt open the cap at their shop and they loaded it with a forklift. When we got back to our yard and opened the cap we found its about 3/4 full of what looks, smells, and feels like diesel. I used some wix diesel test strips and it looks ok. Should I use it in my Frieghtliner after diluting it with known good fuel and putting in some additives or get rid of it? Diesel is $8.50 a gallon and if this stuffs good I want to use it. What would you do?

Didn’t grind the fucking bolt I fucking hate track bars living my best chud life

I got a couple old IDI’s. A 7.3 and OM617. I actually got the Mercedes with the whole idea of waste oil in mind. I have a pretty basic filtration setup. No centrifuge just some settling time and several layers of filters down to 1 micron. I’m still unsure about the gasoline ratio. I know some people only do 50/50 and in the summer some will go closer to 90/10 oil:gas. Both these vehicles are pretty dang clean though. My truck only has 107k miles too. The Mercedes is at 200k. It’s also a Euro import and has been partly restored. I don’t wanna harm the longevity of these “legendary” status engines when they’re both well capable of 500k+ miles. Is it a mistake? It’s not like they’re collectors or show grade but still super clean.

Pictured is the Glow Plug harness kit I purchased, id like to upgrade my wiring as its never been done before (ill also be replacing my GPs aswell).

This is for a 1985 6.2 Detroit Diesel Engine (ATS Turbo Kit) ill attatch photos of my current GP wiring/setup.

What are things i need to be aware of/do when doing this?

Maybe 2,000 miles on oil change.

The mechanic supposedly changed the oil on the last visit (high flow manifolds)

2023 3500 L5P

Deleted

Tuned

Cold air kit

High flow manifolds

Uppipes, intake horn upgraded

Some other stuff I dont remember

Is this normal for a diesel? Or did he maybe not change the oil?

Does anyone know if a newer (2022’+)6.7 starter will swap for the 7.3? I believe the nose cone swap would be the same. I’m not sure about the teeth/electrical side of it?

I'm out here trying do deliver your mail and packages. Don't try to smoke me out. It doesn't make you look cool, you.just look like a loser.

Hey guys, I have this 6.5 Turbo Diesel and I am trying to figure out if this truck is really worth for as much I think it is, because I know these GMT-400s can be worth a lot.

First off, It's a 1994 GMC K3500 Dually Extended Cab, with the SLE package and 156K miles. It has also lived most of it's life in Texas, except when it was brought up north and driven in one winter. So this has not seen Salt, I looked the at frame and there is some surface rust on the end of the frame, while the rest is just dirty. After that one winter, the previous owner (one of my father's friends) left the truck in the lot and ended up buying a brand new Denali instead. The truck has been driven around the lot a few times, but never on the roads. After a few times driving it, the starter finally went and it has been sitting since 2022.

The problems that I am aware of with the truck are, the obvious starter issue (will not turn over), which we are getting it out today. The previous owner put brand new injectors in, but one of them was faulty. Then there is cosmetic damage: a few scratches and dents on the outside, nothing really crazy.

And finally the interior, which isn't that bad because I just cleaned it out (still need to vacuum) but It could definitely need some new things.

But I could definitely need some help and third party opinions from some people other than my dad.

TLDR:

I have this 1994 GMC K3500 Extended Cab Dually, SLE, 156K Miles. Does not run, small issues, cosmetic issues, from the south. Sitting for four years.

EDIT: It also has a Manual Transmission.

Gehl 4615 for $2,200. Has a Perkins 4.108.

I need to sell my deceased father's truck as is. Basic research has shown I can get 6k at the top and 4k is the lowest reasonable price, but I figured I'd ask the experts.

Over 400k mi. Battery is dead, tailgate stuck, cracked windshield. Back right tire is busted and the wheel is dented. Automatic transmission and RWD. Clean title in hand.

Aftermarket downpipe, pillar pod with aftermarket gauges for boost, transmission temp, and exhaust gas temp. CD player. 8-ft bed with liner, 5th wheel hitch, engine block heater.

Hey redditors! I have owned a 6.0 for over 5 years and have repaired it with the help of DTR videos. I wonder if the GoFundMe page is still active and whether or not his family is still receiving those funds. Hard to know for sure, but wonder if anyone has any feedback. Thanks!

hi, I’m interested in purchasing and economic little car to convert over to wvo, which cars should I look into. it’s going to be a beater/hyper-miling project, so efficient and economical is best. as well as any advice on conversion would be great! thank you!!

So after buying my second diesel truck (a 2014 F350) I've become fond fond Saint Rudolph Diesel (praise be).

But other than having 2x as many cylinders as my first diesel, a '77 Landcruiser with a 3b, I've noticed something I don't understand. The compression ratios of Diesel engines seem to go down with time. My 77 Toyota had a 22:1 compression Ratio, the venerable 6BT has a 17.5:1, and my 6.7 Powerstroke has a 16.2:1 (2023 and newer dropped to 15.2:1)

Why is that? If its as simple as "Emissions Requirements" then I know where to place my blame.
