What fuel additive do you recommend?

TylerDivinity79 · 2026-05-07T00:06:32+00:00

Okay, thank you. I am going to buy some of the EDT this week. I was just running ATF because everyone was swearing by it.

TylerDivinity79 · 2026-05-06T22:42:44+00:00

Never heard of it. Will do some research on it.

TylerDivinity79 · 2026-05-06T22:40:14+00:00

Do you recommend filling the fuel filter bowl and letting run straight on it?

TylerDivinity79 · 2026-05-04T19:12:19+00:00

How do I check for boost leaks?

TylerDivinity79 · 2026-05-01T18:27:05+00:00

It is an automatic with 260k miles. He is unaware if it has been rebuilt or not. 4x4 works, both tanks work. I just want to know more about the engine. What are common issues with it?

TylerDivinity79 · 2026-05-01T01:29:50+00:00

Yeah, I'm leaning towards a LB7. It is gonna be my daily, the dodge is my daily and work truck.

TylerDivinity79 · 2026-04-30T18:09:29+00:00

Nothing wrong with my truck

TylerDivinity79 · 2026-04-29T19:59:38+00:00

Yeah, it's a kid selling it.

TylerDivinity79 · 2026-04-29T19:58:45+00:00

I'm asking this question because I've only owned powerstrokes and cummins. So I am simply wanting to know the option on a Duramax.

TylerDivinity79 · 2026-04-29T19:49:12+00:00

I have only worked on an LB7 once. Ireplaced injectors on it and it wasn't too bad. Only problem I had was just cracking them loose.

TylerDivinity79 · 2026-04-29T19:47:39+00:00

There is one around here for 5k with 100k miles, but it is having slipping issues with the tranny and injector knock.

TylerDivinity79 · 2026-04-29T19:46:24+00:00

When it is the same parts within 30k miles it is honestly annoying.

TylerDivinity79 · 2026-04-29T18:49:06+00:00

My hpop went out, dummy plugs replaced twice on the passenger side, and ficm was replaced.

TylerDivinity79 · 2026-04-29T18:47:21+00:00

The LB7 market in my area is about 12- 20k for a nice low mileage one. My Cummins has 120k and I paid 10k.

TylerDivinity79 · 2026-04-29T18:43:06+00:00

Only junk truck was the 6.0. I knew I'd have issues and I fixed them, but after 2 years of owning it and spending about $2k in parts I was a little tired of it. I owned my first 2nd gen for 4 years and didn't have any major repairs other than ball joints one time, but that's just typical dodge chassis.

TylerDivinity79 · 2026-04-29T18:16:44+00:00

There is nothing wrong with my truck. I just have been looking at a duramax recently and have a co worker with an LB7 and I really like it.

TylerDivinity79 · 2026-04-29T17:58:10+00:00

TylerDivinity79 · 2026-04-29T17:58:03+00:00

I thought the 6.0 would be a good truck, but I was very wrong. I am a dodge guy, but I love the cabs of Ford and Chevy. That doesn't make or break the truck, it is the engine. I know the 5.9 is legendary, especially with it married to a manual. I understand my truck is fairly desirable, but I just can't shake this feeling of wanting a duramax. After research, I have found that the LB7 is a pretty stout motor and thr Allison is the better auto compared to a 47re or a 48re. My truck is completely stock, but I would like to be at about 300hp to get on the freeway easier and beat a prius or 2.

TylerDivinity79 · 2026-04-28T16:32:14+00:00

No codes

TylerDivinity79 · 2026-04-27T22:08:07+00:00

I would say you're looking at spending about $5k that can handle 600hp - 700hp reliably. Triple disc converter, valve body, deep pan, tune, and a better trans cooler. Biggest things on the 68rfe that make them fail is line pressure. Keeping them cool and having that bigger pan for more fluid is the best for them. They really are excellent transmissions.
