Stuart,
Maybe we are talking two different things. I removed the oil line that is inside the pushrod compartment and blew it out. It was not plugged. When I say oil distribution galley I'm speaking of the main oil supply valve and galley on the drivers side of the block. It feeds oil to the rear main and rear camshaft bearing and then on to the oil line in the pushrod compartment and to the rocker oiler. If the passage from the main oil supply galley is plugged, I think I'm screwed.I did disconnect the line at the center oiler and ran the engine. No oil from the line. Any ideas? Also, what does the oil distributor (drivers side) do? The shop manual is unclear.
