Pablum! Offhand, neither of my diesels had a potential for a $10,000+ repair from a few drops of water in the fuel tank!

There, fixed it for you. :B

I spent way to much time looking for the correction :B Make it BOLD next time :W Heck most don't have any water, just a bad pump.

Something that is very different with diesels is the rate of change with the manufacturers coming out with new versions which fix problems with prior year models but introduce new flaws.

Really? Care to elaborate on the 5 different engine designs of the Duramax?

LB7 - The Original
LLY - Known for overheating, but had VG Turbo
LBZ - Fixed overheating, most reliable known
LMM - 2007 emissions compliance
LML - 2010 emissions compliance (DEF)

Completly disagree, as it is the same basic design with enhancements "required" to meet stricter emissions laws and continue to boost output numbers.

Now if you had used Ford diesels as an exammple (6.0 turd, 6.4 semi turd, and now 6.7) you would have a solid argument as these are actual "different engine designs"

Agree to disagree I guess. Just noting that GM identified the engine as 5 different designs. However, I'm under the impression the LBZ block had some reinforcements and foundational changes that make it more desired than any of the other pre-emissions duramaxes no?

New truck advantages
- Quiet & clean (on par with current gas trucks)
- Improved tow ratings, brakes, exhaust brake, etc. Overall more capable tow vehicle

New truck dis-advantages
- High pressure fuel system repairs can be very costly (+$10k)
- Emissions (DPF, DEF) seem to be the most problematic issue on the newer trucks.

Pretty much sums it up.

New diesels are the gorgeous girlfriend who likes expensive things and just might leave you for a rich guy or a 24-year-old with a six pack someday.

Older diesels are that average looking wife you've known for years who maybe has put on a few pounds and consigned her high heels but has a big heart & isn't going anywhere.

LOL... I like the analogy

Chop me down for this but; most of the guys on here are not buying a truck. They are buying a toy, plain and simple. If they can't pull the steepest grade in the rockies at 85 mph, somethings wrong.

My brother drives delivery trucks for a lumber company and one of them is a 2011 F 550 with a 12' hoist flat on it. He said that truck is stupid powerful. Never even when hauling a full load of prefab construction fence, with skid steer and trailer has that truck even thought of slowing down.
I don't know if Ford lets you spec your engine in a 550 so I am assuming its a Powerstroke.

The old trucks did the same job just not with the speed and muscle, and luxury the newer ones do. Most of the guys on here could get by with a lot less than they have but "getting by" takes the fun out of it.

It might be a V10...a 30-valve (362HP) and 4.88 (or 5.38!) gears would make for a real barn-burner!

Cheaper to buy is the only one I can think of.

Emission garbage, fragile injector pumps, and the potential for multi-thousand-dollar repairs! (One tractor at work just got a new DPF...just the PART was close to $4500!)

You consider these to be separate engine designs? The basic design of the Duramax has not changed since inception.

It is true that certain items can be retrofitted, but they all have slightly different architectures. It's almost as simple as the chevy LS small block. It's been the same basic motor for the better part of 10 years, but each generation where GM designates a new code has quite a few improvements and changes (even though they're difficult to tell). Here's a good webpage showing the design changes through the generations: Diesel Power Magazine

Wikipedia has a nice breakdown as well: Wiki

lol you're clueless

using you're logic cummins has three different engines available in 2013

Nope, mechanically speaking the three Cummins motors ratings are mechanically identical. All that truly differs is the ecu setting. Also, to call one clueless and insult them does not add to the conversation but only serves to boost one's own ego. Also, it is gm that differentiated the identification of the engine. I'll agree that some of the tweaks are minor between the generations, but the lbz was the real changer with some large mechanical changes. I'll be honest and say I don't know how much is interchangeable between the blocks, but they are identified as such. Cummins does make many versions of the isb as well with different cm versions. The ram/Cummins forum trend to identify their engines by the major changes such as 12 to 24 valve, or injection system from vp44 to common rail. Otherwise, by your logic, Cummins will have only made 2 motors since the 80's for dodge/ram. Hell, the 6.7 still uses a lot of the same parts add the 5.9. Is that a change? Or how about all the 5.9 motors from 89 to 2007?
