Subject: Re: oil
Yeah, I had the same problem before installing an extra oil cooler in an
82 westfalia (side mount). The engine was pulling 20 psi at speed prior
to installation but afterwards oil pressure increased by 10 to 20 psi
(depending on the air temp.) Now with the oil cooler mounted above the
tranny, I am thinking of installing a fan hooked up to an oil temp
switch. As David Schwarze said, 20 psi is far tooo low; rule of thumb 10
psi per 1000 revs. Any ideas out there what might be the source of
consistently low oil pressure? DC
By the way I just got back from 10 days in Brussels, and saw a sum total
of 2 air cooled Vanagons, more than 50 wc vanagons and about 10 pre 80
busses. The most numerous of all were the Eurovans (transporters). Still
the Citroens of all vintages remained the most interesting.
(if you are wondering if I spent my time counting Volkswagens, the answer
is no, this info comes from walking around the town).
