the 5.9l cummins is a much better motor than the indirect injection
6.5 GM diesel, however, it doesn't mean that it was a bad engine.
other than the electronic pump driver failures in the later models,
they were pretty reliable and had 195HP/ 395 tq (iirc) on a TD.
I think you're going to be hard pressed to fit the 5.9 into a 88-98
chevy pickup as they weren't designed to fit an I-6 into them, unlike
the Fords of that era with the 4.9l gas I6 or the Dodges with the
Cummins. you'd probably have better luck trying to get one into a
72-87 chevy as they had enough length under the hood for the 250/292
See you guys have to start talking in K5 talk. I relate all changes in the
world to when major changes to the K5/Jimmy were introuduced. :-)
Like in 1984 a bold new grille had a bi-level design with three
black-finished horizontal bars, square headlamps in both sections
(optional), parking lamps behind the bars on the bottom, and a yellow bow
tie on the body color strip in the middle. Only 4x4 models were available
for 1984. Fender badges now identified these trucks as K5
models..................... and....... I was also born.
Find an Oldsmobile with a 5.7 Liter Diesel, hehe. Turboless and no balls
what so ever, buddy has one in a Cutlass Supreme, 1982. Regular gas block
converted over to a diesel engine. Obviously using diesel engine components.
The 6.2L and 6.5L were supposed to be what the 6.6 Liter is now, smokeless
and less noisy, took Isuzu to. Shame on GM!!
I used to have a 1981 Buick Century with a 350 diesel in it. The
original engine was replaced with a crate 350 diesel in 1986. By
then, GM had all the bugs worked out of them. That was the best
running 350 diesel I've ever seen. Got 27 mpg too. I think I put
almost 60,000 miles on that car in 2 years before I got rid of it a
couple years ago
As far as the Duramax goes... GM has contracted with Isuzu since
before you were even born. What do you think the Chevy LUV was? A
re-badged Isuzu Pup. How about the Isuzu Hombre? All it is is an
S-10 with a different front clip and different badges.
I'm sure the Duramax is a decent engine, but I'll never buy a V8
diesel over an I-6
I did a couple of quick measurements between my 88 K2500 and a '90
F250 we have at work... my truck's engine bay (firewall to back of
radiator core) is and inch LONGER (41" vs 40") than the ford. so the
length shouldn't be a problem.
OK all of you Comedians can stop stop about the GM Diesels. They
great engines and where in great trucks. Like someone else said you
are not going to be able to get the 5.9L Cummins into the Chevy, it's
just too long. Anyway unless you have a donor truck, you are going to
pay a lot of money for a running truck and most likely anything that
is cheap is going to be a totally wasted truck. If the truck is nice
then someone is going to fix it.
Any way good luck in your search.
Worth a damn? That's a tough one. If you have owned and operated a
Cummins powered vehicle, then you will be sadly dissapointed by the
6.5L, as you would with any of the other pickup diesels. Otherwise,
if you have nothing to compare it to, then it won't seem so bad.
They are decent engines in their own right, but they had alot of
injection pump and glowplug issues.
I don't know if I would waste a good B-5.9 Cummins on a truck of that
vintage. If it were me I'd be looking for somthing older, with solid
front axles and no computer controls.
I've always wanted to put a B-5.9 in a late 70's or early 80's 1-ton
4x4 single wheel, with a New-Venture 4500 5 speed behind it. That
would be the ultimate truck now...
As a I6 Diesel are naturally balanced and very minimal vibrations compared
to a 90 degree configuration. But the duramax is an awesome engine. I know a
guy now who owns one with a 5 speed automatic Allison trans and the truck
has 300,000+ miles, only work ever done to the engine was something to do
with the fuel injectors.
Not so much that, I was referring to the fact that the I6 is a much
more efficient and reliable design for a diesel. Hence the reason you
will be hard pressed to find anything but an I6 in a semi or road
I don't even want to know how he racked up 300,000 miles in less than
5 years. But that's not really comparing apples to oranges. all
highway mileage in that short amount of time is alot different than
driving it everyday for a few years.
He's my boss. He owns Great Lakes Limousines. We stretch He's, Towncars,
Escalades, ect. He is always traveling all over the U.S. buy cars, trucks,
SUV's or whatever. He redoes some of them and sells some of them as is since
most of them come from the south and out west. He pulls a 5th wheel 4
vehicle car hauler. From day one of owning this truck, 95% of the mileage
has been pulling this huge ass trailer.
