Did you have the cold start pushed in when you checked the timing?
Any air in the clear lines to and from the pump??

There are no bubbles through the clear line to the pump when the vehicle is running. I do not have a clear line running from the pump. I did notice however with the vehicle off air bubbles traveled from the pump to the filter, And yes when the timing of the pump was checked the cold start lever was off.

Air leak at the pump then. Start with copper seals on In and Out bolts, rubber lines at both and at injectors. Other than that there are the front seal and the two O Rings under the covers up front. Top seal and O ring at fuel check valve? I wouldn't expect the copper washers to be bad at the back of the pump but you never really know till you look.
Did I forget any? O- ring on Throttle shaft. I think that is all.
Rebuild kit gets you all of them except the front seal that is a all by itselfer.
Keep us posted.

A clear line on the OUT to the tank return can save time...
Shows if air is infiltrating via IP seals: return fuel will look foamy when running if air is getting in, solid/clear when air is purged.

I would highly suggest just a piece of clear line off the out bolt for the purposes of testing here. Best way to know that I know.

Clear piece has been attached for testing purposes. For about 10 minutes of running there was a nice stream of bubbles coming from the out bolt, which cleared up completely.

That seems a long time to me, even if only at idle. The pump cranks nearly a liter of fluid through it in a minute and a half. So I would be looking for a leaking seal somewhere along the line. Maybe even in front of the fuel filter.

No fuel leaks at all. The pump was resealed a year ago. Maybe the Prothe fuel filter is finally giving me issues.

What style filter is it? The one with the heater valve thing that doesn't cycle back fuel to the tank until it reaches a certain temperature? Those are a bugger to bleed the air out of...

Well blue smoke stopped, now just a haze of grey smoke at idle and only running slightly lopy. Now what?

Any and all Ideas are welcome. Should I just drive it and see if the smoke clears up?

I have pondering this issue over the last month, and I I do remember something I did differently this time, I bumped up the timing to 1.00 from .90 . Would that account for the haze of gray smoke?

Possibly, but remember it is a diesel. It will smoke some. Mine didn't have that much when warm, but when cold it would give the white cloud like so.
