[PREP] Isuzu questions for Doc1

I am very interested in your comments on the Isuzu diesel trucks.
I'd very much like to have you expound on:

1. the best model to look for
2. how to locate one
3. what sorts of repairs one would do and who to do them

I agree that soon the time will come when one cannot buy one of these for any reasonable price. I need a pickup rather than a car, sos I am very interested in any help you could give.

I well remember the '73 oil embargo. In less than a week one could not find a fuel efficient vehicle of any kind anwhere.

I think you are right about this. It probably could be the best investment I could make!!!

I had an '86 Isuzu Trooper with the TD hence my handle. I just ran across one at a car lot. they had two troopers, one gas.
I have heard that a few '87 TD's made it into the US, but other than that, '86 is the only year.
The pickups were available in a broader range of years,but they are not turbo's and in my view,you don't want a naturally aspirated diesel and they can't be upgraded as the pistons aren't rated for the turbo.
As for maintenance, change the fuel filter and keep a 2nd new filter in the truck. the timing belt must be changed every 50k miles. If it goes,so does the motor. parts should still be available thru an Isuzu dealer who will have to order from Dallas, I think.
The tranny and transfer case use motor oil, not gear oil.
Keep the rpm's under 3000! They were geared for the 1986 speed limit, so forget cruising at 75. I added 31" tires just to run at 65.
Great mpg,21 in town, 25 hwy. Hwy could be better if not for the aerodynamics of a brick in the wind.
They are scarce, but search online. There are other makes w/TD's out there. You can find Toyota BJ-70 Landcruisers brought in from Canada as well.
Good hunting...:)

I can recommend Isuzu trucks highly. I have a gas '92 Rodeo 4x4 that's still going strong after 143k miles. Always gets me where I'm going, even if it's down a muddy dirt road, thru sand or snow. Change the oil regular and it will make you very happy.

Isuzu question

Tennesseean,
Everything Dieseltrooper said (did you pick up that Trooper on the used car lot, Dieseltrooper?). Like he said, you'll only find the TD Trooper in '86 models. Diesel pickups are much more common and span many model years. Isuzu made a few different diesel engines. Both of ours have the c223 inline 4, which is known for its longevity/reliability and a friend gave us a spare engine.
My wife's '86 Turbodiesel Trooper gets close to 40 mpg, if driven carefully for maximum mileage. My '83 P'up (pickup) will get just a hair under 50mpg. Though both vehicles use the same basic engine, the TD Trooper has a turbocharger and is considerably heavier than the P'up. The Trooper also uses full size 15" truck tires, whereas my little pickup uses 14" tires.
The pickup's driver's seat sit much lower to the ground that the Trooper's and hence, makes it feel like the little truck goes much faster. Almost like a go cart!
As far as mechanicals go, do all of the usual stuff: Listen carefully for bad engine noises (but remember, it's a diesel ... it will be much noisier than a gas engine!). There shouldn't be any knocking under accelleration. It shouldn't produce excessive smoke at normal throttle positions, but will produce black smoke if you give it excessive throttle at any speed. If you see a little excessive bluish smoke at a cold startup, that's ok. It indicates valves or guides are getting a little worn, but should go away quickly. The motor should still last a long, long time. A lot of smoke which doesn't go away could be a tired engine. Another thing which can cause excessive startup and driving smoke is trouble in the injector pump or injectors. Sometimes this can be cleared up with fuel additives.
CHANGE THE TIMING BELT!!!!!!! This is IMPORTANT, and yes, I'm screaming! They should be changed every 60,000 miles. If the belt lets go, you will ruin your engine. The c223 is an overhead valve engine - not an overhead cam - and a lot of folks think it doesn't have a belt. Wrong! It does have a belt and just like its overhead cam cousins, if it lets go, the pistons will hit the valves and lunch the motor.
Another thing to look for is rust. Isuzus have a reputation for rusting out. For some reason, this seems to affect the old pickups much more severely than Troopers. I make it a point to squirt the undercarriage with oil whenever I work on it. I squirt everything, frame, body, running gear! It makes a short-term mess, but does keep the rust down!
If you have the room, I'd also advise you to look for broken parts vehicles if you can drag them away cheap enough!
IMHO, getting your diesel vehicle is only the first half of the fuel shortage preparedness equation. The other is fuel storage. Start making those preps now. Find some good, solid 55 gallon steel drums and smaller plastic barrels. Build a small fuel shed. This will help keep your fuel supply from prying eyes and also help stabilize temperatures which is good for storage. If you are going to keep substantial amounts, build an small earthen berm around it to prevent spills from spreading. This isn't eco-nut or "green" advice; it's common sense. Diesel is much safer than gas, but it will burn fiercely if ignited. You don't want a spreading diesel fire to consume your house! I've already got my pumps and barrels, but am still looking for other storage options. Maybe a big old, condemned propane storage tank would work. I haven't had any luck finding a midsized metal fuel storage tank (cheaply) yet.
Lastly, sock away spare oil, air and fuel filters. Get an extra timing belt or two. Store extra Rotella diesel lubrication oil and fuel additives/stabilizers.

Best regards
Doc

Yes Doc, I bought that one for $2000 at a lot in Pueblo,CO.:D

I just looked on Ebay using "jeep diesel" and found a 77 CJ7 with a 1995 6.5 GM TD. Pretty cool...:)

Fuel mileage

Tennesean,
I just reread Dieseltrooper's post and my own and wanted to clarify the mileage issue so that you weren't dissapointed if you bought a TD Trooper.
We've experimented with my wife's Trooper and put large diameter tires on it. I said she can get close to 40 mpg if driven carefully for maximum mpg and that's the key! I was talking about intentionally driving - slowly in top gear - for maximum mpg. When driven normally at highway speeds, you'll get closer to the mileage Dieseltrooper posted. But for some reason, her Trooper has always gotten better mileage than the books would indicate. I don't know why, but I'm not one to slap a gift horse...
My little pick up, on the other hand, will get just under 50 mpg at 55 miles per hour, just as the EPA estimates claim. It's a much lighter vehicle and sits lower to the ground, reducing aerodynamic resistance. If I push it up to 65 or 70, the mileage falls off, but not too bad.
If you want maximum mpg, go with the pickup. If you want four wheel drive, a (much) nicer interior, with still respectable mileage, find a TD Trooper.

Best regards
Doc

Adding..........


STAY AWAY FROM GM DIESEL MOTORS.


I worked for GM for years and most of our pissed off customers were the ones with the diesels who had to have the truck on the lift half of its life.

The bright side is that the injector pumps are warranteed for life, the bad part of it is that the injector pumps are such a problem that they "HAD" to warranty them for life.

On any given monthly warranty audit we would have 4 6.5 motors and 20 odd injector pumps sitting on our loading dock ready to be inspected by the auditor to make sure it wasn't a warranty scam.
 
Ditto's on the diesel......

I saw that one Dieseltrooper..the CJ with a 6.2..a little stiff on the price though..about 9000..wasn't it.

I had a 86 Gas Trooper,It would go...and go.But the heads are not tapped deep enough for the head bolts.....
...I know..I blew a head gasket...And a good mech. had them tapped deeper..No problem

If your going for MPG,look for a Rabbit diesel.I had a diesel pickup that got 55mpg...I would forget where I had bought fuel last!!:D

I never had a GM 6.5L engine, but had some 6.2s. Good engines, if weak. I prefer NA engines, as there's less to go wrong.

FWIW, if you're looking for a little diesel PU, there was Mitsubishis. They had a 2.3L TD-and the Dodge Ram 50 was the same truck. Ford even offered that engine for a couple of years in the Ranger.

I wanted to add: mine had a bad oil leak when I got it. It only leaked while running and I had a hard time finding it. It was the oil cooler that is located underneath the filter. The new cooler was $160 from Isuzu and requires a large socket (1"?) to r+r.

thanks for all the input, a Rabbit question

Does VW even make a diesel pickup?

According to consumer reports Mitsubishi trucks have a much higher problem rate than Nissan or Toyota.

I get 30 mpg highway with my 92 Nissan 4 cyl with a camper top.

No question but driving habits influence both gas milage and engine life.

IIRC, there was a Rabbit pu diesel. But as much as I liked my dieseltrooper, any of those 80's vintage diesel models are going to be tough to find parts for. Even Jeep put out the Cherokee with a french TD. Oddball, one year only types are not going to be a good choice for preppers,imo.
Are you really keen on a diesel or is your primary criteria fuel economy?

VW did make a Rabbit PU about 20 years ago. It's front-wheel drive, so not much of a hauler. International had a Nissan TD in Scouts about that time, too. Pretty small engine, IIRC-maybe 193 ci.

Forgot about that Cherokee-that was roughly the same time that Renault and Chrysler joint-marketed cars.

My Ranger gets 27 mpg with 4 cyl/5spd, but I can drive it fairly hard. 30 mpg with good gas.
