Thanks for the additional info. If you have the timing information handy I will pass it on to the shop. It would seem that whatever information they used didn't work. I have to start with the belief that the rebuilders did the job correctly, and that sitting on a shelf "a few years' didn't hurt anything either [it had been tested by the rebuilder so it should have been lubricated, and was sealed]. I suspect the mechanic just wasn't familiar with the procedure.
I am to the point of thinking it is a connection problem or a faulty gauge.

Air Bubble: park car facing up hill on slight incline with heater controls on full heat (or put front axles up on jack stands), drain off a gallon or so and pour back into the block via the top radiator hose. Pour until coolant is about to run back out, re-connect hose and put remainder into expansion tank or radiator. You may have to squeeze the upper hose to 'burb' as much air as possible out as adding those last few pints. Keep squeezing until you can't get any more air bubbles into expansion tank/radiator. 2) Sounds like pump timing is off and maybe the linkage is not adjusted correctly. Let us know if you need the instructions for timing the pump.

I have two issues that are giving me problems: 1. The temp gauge usually holds at 100 or a degree or two above or below. It has started to register hot for a time every few miles, starting in the last few months. I have had the thermostat replaced, radiator flushed and the temp sensor replaced [old one was a bit corroded], and this morning when it jumped up to 120 I headed back to the shop and a temperature sensor showed nothing on the engine or cooling system over 180 while the gauge was at 119. Sometimes it jumps [like an air bubble] and sometimes it climbs and goes back down slowly. Tomorrow the cluster will be pulled and the resistance on the wire checked, as well as the vacuum lines. Any other thoughts ? 2. My injection pump has been making noise [much louder in the car than outside, but a stethoscope on the pump found the noise was within]. I got a rebuilt pump and had it installed - but the mechanic doing the install really doesn't have any history on those things. While there are always 3 or 4 MB's in the lot it turns out I am one of only two diesels they take care of. When I picked it up it was already running, and smoking more than before, though most of the noise was gone - or at least quieter and different. When I started it the next morning it was making a fair amount of noise and putting lots of smoke. It lessened when it got warmed, and by the time I have driven it a few miles the noise is pretty much gone [you can still hear it a little bit over the engine noise], the smoke lessens, but is still much more than it has ever been, and the power seems lessened. At this point if I want to get moving in a normal fashion I need to turn off the AC, but it still does not seem as peppy. I know I am not accelerating as hard as usual because I am sure something is wrong somewhere, but it still seems a tad anemic. I also assume that those clouds of black smoke the tend to surround my at stop lights is fuel that is not being burned as it should. At $4.199 / gallon I don't like that. I did get my 250k kilometer badge over the weekend - they do look nice. Wonder if I should buy the $2,200 MB watch from the catalogue to go with it . Is there a 'normal' spot to mount this? At the moment it is angled behind the rear speaker to push up against the rear glass while I decide if I want to put it on the front grill. Thanks in advance for any suggestions. I'll take them down to the shop in the morning.
