Richard
you say its a fresh engine so I will point out a couple of things that
come to mind first if you used the Victor reinz gaskets set it has an
oil pump gasket that is thicker than the part # calls for its the same
as a bug in part # but it measures .006 to .008ths thick all other
gaskets in every other set bug and vanagon are .004ths thick.the
thicker.008ths gasket gives you 1/2 the oil perssure when used. I have
posted this to the list in the past and its worth repeating. the next
thing that needs to be checked out is did the big ends of the rod get
resized and new bolts if not then this could be the reason for your low
oil pressure. this is covered in lenght on my web page the article is
named low oil pressure at warm idle
good luck
