GM 3.0L inline 6 diesel specs leaked

To be fair the transmission issue was not a Cummins problem. They did not build or design the 5spd Getrag.

The KDP did kill a few motors but most just needed a new front timing cover case, some were "fixed" by owners with JB weld and others like me spent the 2 hours it takes and Tabbed the pin with a scrap peice of metal before it moved.

"The early Cummins had issues as well killer dow pin and problems with 5th gear in the transmission."

Both were taken care of by the original owner and it's still VERY dependable at 400k. So much so I sold it to a personal friends Son. He loves it!

I look forward to seeing if this (and the Ford baby diesel) can prove themselves reliable and durable over the long run. I'm going to say the Ram EcoDiesel is......what I'd call so-so for those categories. Not a disaster by any stretch, but enough issues I don't think I'd buy one. Diesels aren't the bulletproof workhorses they once were IMHO. I think they are getting better than the choked up junk they passed onto consumers in 2008 - 2010 (no matter the brand), but I still think today's diesels, although very powerful, don't measure up to the durability and longevity of the 5.9L Cummins and 7.3L Powerstroke in their best iterations.

The Cummins 6B had 5 years of refinements in tractors before Dodge ever put it in a truck in 1989. I doubt any engine now or in the future will have the long term "testing" like that before being sold in a truck. Not saying other engies aren't like it but the 6B(T) was designed to run at full throttle under full load for hours on end usually only being shut down for a fuel and preventive maintenance.

And one suggested a while back that this I6 would produce less hp than the V6 diesels because it's an inline.

Grit Dog, check your PM from me from 10/4

It sounds like a decent engine, I like the simplicity of a I-6 engine. The 4cyl gas engine sounds interesting as well.

I popped the hood on a Ford Ranger here in Belgium today. The truck had a 3.2L I-6 diesel and put out an advertised 197 hp. Not quite what the 3.0L trucks are doing stateside, but I too like a good I-6 layout. Everything was nice and accessible. Even my 6'3" frame fit fairly comfortably in the back seat. This will be a nice addition to the Ford lineup once it begins stateside production.

Hey Vern! First I've seen you post over here but enjoy your posts on ram forum that's for sure.

I think this I6 diesel will do well for GM, at least I hope it does. We are very lucky to have so many options when it comes to trucks these days. I've always liked I6 engines. The dodge slant 6 was very durable, as was the 4L, the gm and ford I6s were stout especially Ford's 300 I6. It will be interesting to see how they make out once they are out and have some miles on them.

Lol yea good catch 442 TQ.

THIS may be my wifes next winter beater. EcoD 4door Rubi, baby!
I wouldn't p!ss on the little V6 gassers they've been using if they were on fire.
Jeep shoulda kept the 4.0. Wish they'd kept it a couple years at least into the 4 door Wrangler models so there'd be some available with real engines.
