In my (limited) experience with IPs I've found a lot of gunk in them - perhaps removal of one of the side plates to see if it is full up with muck is worthwhile? The oil might not have been draining...
...the oil paths might be restricted.

On the Older Fuel Injection Pumps that are not lubed by the Engine Oil the Parts inside are also in better Shape and nice and clean.
The problem with the Older Pumps is people don't know they have their own Oil Sump and that you need to check the Oil level, add Oil and occasionaly change the Oil.
Some People never checked and ruined their Fuel Injection Pumps.
In that past there was a lot of inline Fuel Injection Pumps that had that were not lubed by the Oil from the Engine.
Where I worked We always filled them with straight 40wt Engine Oil even if the Engine used 30wt or 20wt Oil.
