>>Actually, the anti-drain valve in the filter will keep the column of oil
above the filter
in place. It is not there just to keep the filter full of oil (which would
happen anyhow
because the filter is upside down). <<
I don't think so Tim. Anti-drain valves are a "one way" valve. They are
for filters mounted in an upright position so that the filter stays full and
does not drain back into the oil pan. This is to ensure pressurizing of the
system as quickly as possible on start up.
On a filter mounted upside down, as on my 97 Dak, the filter being full of
oil, it would also hold up that column of oil you refer to....without the
need for any valve. Simple physics.
An anti-drainback valve on a Dak filter doesn't hurt anything, it just
doesn't do anything.
