My manual is for 1981. This explains the difference. If I could get my computer to delete the half-loaded software for my scanner, so I could properly load it, then I could actually scan these pags for you to look at. <img src="/forums/images/graemlins/angry.gif" alt="" />

I tested the other three injectors this morning, and two opened at 750 psi, one at 950 psi. Real nice. They sprayed better than the first one, though still not too good. If I pumped faster, they misted much better. I'm going to try setting them to about 1500 and watching how they spray then. They may not be too bad. I'm going to rebuild them anyway, throw them in the truck, then do the current set if required. I should clean up the head, throw some rings and bearings in the old motor, just to have it as a running motor instead of for parts. I expected to find burnt pistons or something when I took the head off, but nothing, and very little wear in the cylinders. Also, this engine has the oil pan to fit an S10, and I have a second bellhousing to fit a Borg-Warner T5. The vacuum pump was even working when the engine came out.
Funny about the VW injector similarity, 'cause when I looked at them I thought they looked a lot like the ones in the Jettas I used to have. This is great, as it makes it a lot easier for me to locate parts. The nearest Isuzu dealer is 100 miles away, the nearest VW half that. Most people haven't heard of an Isuzu diesel pickup around here, but diesel VW's are common. I'll make a few calls tomorrow to locate some injector parts.

I'm not sure what to think about the oil brew. I believe that is what caused the build-up, but I can't figure why. I could see it from used motor oil that is full of carbon and stuff, but this stuff is fairly clean. Temp of the oil make a difference? Did this happen because the engine was cold at first switchover? If so, why? It ran fine, no different than diesel when the engine was hot or cold, until after a week of it or so. I have some un-mixed transmission/hydraulic fluid, called Permatran, that I think I will filter and run mixed with diesel in my second tank and see what happens. I had some regular hyraulic oil mixed with the first batch.

Thanks again for the input and info. It's always appreciated.
