Hello,

I hope that that will do the trick but I doubt it.  What happens on the
Vanagons
is that coolant seeps into the block (now where have we heard of coolant leaks
on Vanagons? ;) ) and will attack the babbit material on the rod/main
bearings.
This excessive gap will drop your oil pressure faster than my old girlfriend
did
to me!  A high volume oil pump will only increase the amount of oil flowing
through the system- it will not increase the pressure.  We would run into
similar
problems with Wasserboxers at the dealer and the only way to fix was to either
go the rigged way of replacing the bearings or the customer would bite the
bullet
and buy a reman motor.
