Thanks for the sentiment Dave.
My son is here for a few days from Boeing's annual Christmas shut-down and he's helping me with this. He's an engineer at their BR&T facility, just received an award for his work on robotic assembly, so he sort of knows his stuff.
We removed all lifter pairs and checked the block oiling galley for alignment with the lifter small OD, and they are lined up perfectly. Then we charged the oiling system to check for flow in the galley. Each side is fed from the rearmost lifter bores (4 and 8 exhaust), and each adjacent is then fed in turn. After checking the rear bores we inserted lifter pairs 4 and 8 and then checked for oiling at 3 and 7. Then we did this for the next pair up to the front. For #1 and #5 exhaust we inserted singler lifters into the intake bores.
Kevin Bush installed threaded plugs in all the oil galleries and everything looks fine.
I tested lifter 5 Intake for "springiness" about it's hydraulic travel and found it locked up at the top, against the snap ring. I removed the snap ring and attempted to remove the plunger. The connecting bar rivet prevents complete removal. After reassembly the springiness returned. Whatever was hanging the lifter I somehow managed to remove. I will do the same to each lifter along with rinsing in clean mineral spirits, then immerse them in clean oil before reinstalling.
As far as the block goes I'll remove the oil drain plug and clean what I can without removing gallery plugs with brake-clean. Then I'll start out with a fresh filter and oil.
