I was having some really unpredictable oil consumption, but otherwise the engine was running fine. I was getting about 34 MPG around town, and it always started right up (although when cold, it usually seemed to start on 3 cylinders and the 4th would catch within a few seconds).

I have a good friend from the IsuzuPup.com site and the PlanetIsuzoo.com site, who retired several years ago, after working as a mechanic/instructor for Isuzu. He agreed to overhaul the engine, provided I wasn't in a hurry. So, I drove it to him, just outside of Atlanta in November of 2013. While he had it, he fixed everything mechanical on the truck that needed it. In addition to a new set of pistons, he had the engine balanced at a local performance shop.

Take a look at what he found when he got the pistons out!

I can't figure out why it ran so well. I drove it around 75-85 mph on the highway between Memphis and Atlanta, with no issues. I had a spare gallon of oil, but it was still at the "full" mark after I arrived.

Anyway, the truck finally came home a couple of months ago. I sold the bed while it was in Atlanta, because I found a better one in my local Pull-A-Part. So I drove it home without a bed.

Next is body work and paint.

When he wanted you to not be in a hurry, he really meant it didn't he?

That's nuts. I can't believe it ran like that.

The weather got real cold right after I dropped the truck off, and his shop has only a space heater. Then there was a LONG backlog at the machine shop where they balanced it.

He also upgraded the exhaust system, and he installed a crankcase ventilation system that I pulled from an '86 engine (this eliminated the nasty draft tube that vents to the pavement). The engine looks and runs great now.

While the truck was gone, I found a beautiful specimen at the Pull-A-Part. In addition to the bed, I got the engine and hood. I couldn't pass it up, because it was a factory turbodiesel. If/when I get a job again, I'm hoping to have this engine overhauled, balanced, and replace the turbo with a modern GT1548. That's the dream, anyway.

Here are some shots of the '86 I pillaged. I had a friend who needed a transmission, so he got that, the driveshaft, the instrument cluster, maybe the dash, and some other stuff. I got the engine, hood, and bed.
