Slant clean-up and oiling question

The slant seal isn't in the bearing cap (like SB & BB), but in a separate aluminum retainer that I removed. The crank did have slanted grooves on it, apparently to direct oil back towards the engine, the same as the grooves on the lip of the rubber seal. I only recall looking at the cranks in my 65 SB & BB before and they have similar grooves.

Usually I pull a rod cap off to inspect the bearing and change all if showing wear (dirt tracks or copper layer showing). I looked at one rod bearing on this engine and looked fine. If the rod bearings look good, I don't inspect the main bearings, since in past engines I always see wear on the rod bearings first.

I have one of those "night breather" air pumps that people with sleep apnia use. I left it puffing thru the block and radiator for several days. Our summers get very dry here (10% r.h.).
