Ken,
I had something like this happen when I was first trying to get Fifty
Shades of Brown going a year ago. The guy I got the car from had let his
dad work on it, He had a brand new head but everything was just lying in
the car so I hooked it up and no oil pressure. I tried everything, finally
concluded that there was nothing to conclude and didn't like what had been
done anyway so I started over on a rebuild with new pump, all new machine
work, rings, bearings, etc. I have not had time to get the new engine
started. But now, reading your post about the vacuum pumps, I wonder about
that. I have rebuilt more than a few of these diesels and never had to
prime one for oil pickup, not one. I looked at the oil pump when it came
out and couldn't find anything wrong with it. I tossed it. I wish I had
saved it for a post mortem. In my case it had to be the oil pump because I
am using the same vacuum pump that came out of it in the first place.
Keep us posted on this.
Jim
