Re: 110 Six oil pickup

....would a main or rod bearing failure sound and feel like your knuckles knocking on the oil pan ?

Maybe. You say this is a freshly rebuilt engine so I wonder why you'd be thinking about a bearing failure. Main bearing noise is a dull, low-frequency repetitive thud-type sound, more easily noticeable at idle. Rod bearing would be more of a higher frequency light metallic rapping. I can't see a relationship between either of them and the marks you see on the oil pickup. When you swing the pickup upwards can you see what engine part it's coming into contact with?

The Packard shop manual for the Six gives crankcase capacity as 6 quarts for 1937 and 1938; that agrees with Motor's data which further indicates 5 quarts for 1939 thru 1948. A 1/2 quart over or under really should be irrelevant to the problem.
