Woohoo!  Woohoo! Woohoo!  Wowie Kazowie!  Weird Oil Pressure issue is 
GONE!!!!!!!  I feel like I was finally able to remove a very large and festering 
splinter after many months.  Thanks to everyone.  I am convinced that the problem 
was caused by aerated oil.  I was alerted to such by a p-mail from Shawn 
Wright.  He mentioned that he had heard of problems caused by frothing of the oil 
by the turbo.  The amount of air introduced into the oil would be proportional 
to the speed of the turbo.  This aparently is a normal phenomenon, but not 
normally seen, as air rises out of the oil, and the pickup tube normally draws 
from below the aerated oil.  This was not however my case, due to the dipstick 
being incorrect (past inaccuracy was confirmed when I added oil today).  I 
cannot completely prove my theory, as I changed several things while the van was 
apart (changed bearings that were fine, went to a larger diameter turbo oil 
return line, indexed the turbo to a "perfect" setting, etc.), but as far as I'm 
concerned I'm convinced.  My shoulder hurts from patting myself on the back.  
By the way, I love that van.
