[Vwdiesel] Fixed! - kind of RE: oil pump binding

[Will Taygan]

YES! tap upward on the lower of the 2 vac pump bushings.  Meyle pump
still binding, old OEM pump works fine.  Justin at Greaseworks has
graciously agreed to take the Meyle pump back (knowing the full story),
but doesn't have any of the OEM Febi pumps in stock (they might be
discontinued?) Sooo, order is in with the local dealer (sigh.)  Thanks
for the encouragement.

Will in Alaska.
