Thomas,
This is easy. Drain the 20w50. Remove oil filter. Loosen big nut under
filter. Remove threaded pipe. Replace gasket. Assemble in reverse order.Fill
with 10W30. Drink celebratory beer.

Subject: [VANAGON] Oil Cooler seal

> I need some practical instruction on replacing the seal between the block
and the oil cooler on my recently acquired '86 Synchro.  The old one failed
during start up on a 3 degree day.  This leads to question two.  The oil
that is all over my driveway is 20W50.  The former owner was adamant about
not using a lower grade.  The manual seems to recommend grades appropriate
to temperatures.  Is there a reason for using the heavier oil all the time?
