...Another downfall is the cost of the parts, i know diesel parts are typically expensive, but man the 6.5 parts seem way overpriced for the engine quality...
Oh, i don't know if i'd go that far. Relative to most newer diesels, parts are pretty much dirt cheap.
A brand new set of oem bosch injectors can be had for around 500-600 bucks.
That might buy 1 duramax injector. same deal with the 'stroke or a 24v.
The latest db4 ( with the updated components like ceramic rollers and whatnot) can be had for about the same price as a vp44 rebuild. Way cheaper than a vp44 if you shop around for a quality db4 rebuild, like about 800-900 bucks vs 1200-1500.
If you really look and maybe have some good contacts, there's lots of perfectly good oem pumps sitting on shelves with a dead pmd hanging off them. Most have less than 60-100,000 on the clock. Gm used to rip the whole pump off under warranty work when the all too common pmd failures happened. No one knew (or cared) that it was a simple electronic component failure. Just wanted their customers happy asap (and try to salvage their rep) and then claim the warranty work back to stanadyne. I've got a 30,000 mile pump sitting on a shelf in the garage than i paid 200 bucks for. All nice and preserved/properly inhibited and a confirmed dead pmd hanging on it. Try finding a relatively fresh cp3, vp44 or p7100 for 200 bucks....
Just around 7 grand will get you a redesigned optimizer. 5 grand delivered to your door if you make the right contacts. A thou or so more an you can have the nearly indestructable P400 casting optimizer in your rig. I shudder to think how much a brand new 12v would cost, but i'll wager its close to that if not more. SAme with almost any of the 'strokes. The words " it needs a new duramax long-block" is enough to make you wake up in a cold sweat at night if your truck is out of the factory waranty...
Of course, a dmax and a 6bt are rebuildable if you manage to find a way to blow one up, but thats going to cost you pretty close to what a brand new optimizer 6500 would out the door. The gm 6.5 is a throw away engine though. Not worth rebuilding, which is why I only compare the optimizer to other makes...
Filters are cheap, it runs less oil in the sump (5 liters vice 12 or so) and parts can be had just about anywhere.
It's low po enough for a 4l80e to live behind for multiple 100's of thousands of miles. Even when towing. A duramax would toast a 4l80e in a couple months at just factory rated power. Gm derated the duramax in the vans with a 4l80e just for that reason....so the trans would live. Even price out an Allison? Cold sweats again....
Working on them yourself in the driveway is easy as pie once you have a few specific tools and a little experience with them. It takes a bit to learn the 6.5 ground rules, but once you know them it's about as challanging to work on as an old carbed small block. For an electronic diesel, its probably jusy about as simple as you're going to get. That it does obdii diagnostics and you can tweak them like newer diesels is just icing on the cake....
Plus, its in arguably the most popular/longest/best selling truck body gm ever made. Thats great for scrap parts and the aftermarket is full of stuff for the body.
Whole running 6.5 parts trucks can be had for a grand or less these days.
Thats not so bad.
Factor in that a 6.5 diesel has a dirt cheap purchase price because of a somewhat earned bad rep and it's one heck of a deal compared to shopping for a duramx, 2/24v or the 'strokes. On a pure price for price comparision it's a steal, even if you have to chuck a new engine into it.
Take my truck for example. Sure, I had to throw a new optimizer in it becuase the 599 block died, but I've got a "0" mile diesel for an all in price of around 16,000. Good for another 300-400,000 miles. Price breakdown:
truck purchase- 5,000
Optimizer - 7000
Injectors - 500
Fluidampr-400
new oil cooler- 200
Bill heath tuned PCM - 500 (I do them myself now)
Miscellaneous Bits (WMI, guages, high flow wp, Raptor 100 lift pump, aux fuel filters, etc) - another grand
So that's what? 14,600? for what is a essentially a zero mile diesel that hauls my 35 foot travel trailer with ease. you can toss another 2 grand on to my toal for labor since my engine blew on a trip and I had to have someone else do it. the average joe with a set of wrenches and some time could save that cash.
You just have to be satisfied living in lo po land if you plan to stick with a gm clatter box....
Let's also not forget; after the zombie apocolypse when there's nothing left to burn but greasy teenager skin squeezings or zombie parts rendered into bio diesel the IDI 6.5 will still be rattling along while your duramax, 24V and powerstroke buddies will be the next zombie happy meal!
Well, I think I'll stop there as we've completely jacked this fine young gent's thread!
LOL.
