1981 Isuzu Diesel Engine

jpurdy · 10-31-2002, 09:38 AM

I found a 1981 airstream powered by an Isuzu diesel(6.2)
I called Isuzu and asked if they could give me information about the engine.
They,Isuzu, said that Isuzu had an inline 6 (6.5l) and that the only 6.2l they knew about was a GM engine.
Can someone here tell about this engine??
If this is a V8, is this the same as the converted 350 of the 70's????
is that bad ??? is it durable????

If it is the GM it is NOT the converted 350 (5.7) from the late 70's. The 6.2 is found in many 80's medium duty GM Trucks. I think it is a dependable engine except for the injection pump. People seem to have problems with those at $1000+ a crack.

68 Suburban,
thanks, your right about it being 5.7.....
I found out the engine is an inline 6 and when I said I would not come there for service with a motorhome my question were answered. the feeling was they would not make any money working on motorhomes.

I like your avion....

Thanks for the compliments on the Avion. I was real happy to find it.

I think the Isuzu Diesels have their own issues. I think I read here recently that someone paid $800 for an altenator? Geez...

Diesels are nice for pulling and fuel economy, but I think the cost of repairs when they are needed, far out way the savings in fuel. Unless you are towing 100K miles a year

You may have something there as I heard the same from an owner. He said two things happened on a trip a rock hit the windshield(left half) and an altenator failed. each cost $800 -$900 to replace.

The diisels were Airstreams attempt to sell a "fuel efficent" motorhome. At least they went with a commercial duty motor. As to the windshield all of the motorhome windshields are pricey, that is why I have comprehensive insurance on it even though I will only drive it for 5-7k miles this year.

yes sir,
the comprehensive ins and a good ERS can be a great asset

I replaced the isuzu in our 82 310 with a cummins and it works very well. if anyone needs some isuzu parts i have a nearly complete set of them. ours was a turbo unit

We looked at an '84 310 Turbo unit before we bought our '85 325. The '84 had over 100K on it and a new Isuzu. The seller told me a plastic tube broke and the engine drank all it's crankcase oil before the could get off the road. The new unit cost slightly over $10K to replace vs. $7K that seemed like the standard 454 replacement number.

$7K to replace a chevy 454??? Dang, I would shop around

Bronze Dancer · 11-30-2002, 10:14 AM

Dang is right. Unfortunately that seems to be the right number to use if you're having an engine replaced with a new(not rebuilt) 454. We took one unit we considered to a local Chevy truck dealer for check out. It had a low compression (75) in one cylinder while the rest were OK (120-136). They quoted $7190 for a new 454 long block installed with misc. hoses, clamps, etc.

We looked at anouther unit that had recently replaced the 454 with a new engine at a local RV shop. Saw receipts for $6892.

Spoke to a guy on the phone selling yet another unit who said he had a new 454 after considering a rebuilt or a new short block. His cut at it was the cost of labor and misc parts were such that it didn't make sense to pass on a new engine and it's 5 yr/50K promise.

Not inexpensive is it?
