Hi there Jeff@Jae,
some strange comments in your answer:-
Sumps, dry sumps etc.. Swinging or rotating pickups don't work because all the wetsump oil pumps made in the last couple of decades have the bypass directly back to the inlet not allowing oil to the swinger to keep it sealed and not sucking air. Just forget these things altogether.
We're talking here of a very old Ford oil pump design & the dry sump pumps, which fit in the same location, available for the twincam are really just that pump with a scavenge pump plonked on the end of it.
The design of a rotating pick-up is, as you mention, very difficult in order to prevent air leakage at that location without inhibiting the movement of the rotating part but I cannot fathom out what you mean when mentioning the bypass directly back to the inlet
If you can find the time to explain that more fully I'd be very pleased to discuss this with you further to improve my education.
A most interesting subject indeed.
Cheers
John
