<VV> oil filters

Jeff; I'm the one who has the oil filter adapter. It allows use of a common
PF or PH 13 filter, which has the same basic ratings as the std two gasket
corvair filter. Regardless of this I still use the best rated filters I can
find, usually a WIX.

The adapter simply uses the original gaskets from a original style oil
filter and is held in place by the original screw and gasket set up. It has
a 3/4 inch thread sticking out of it, and accepts a spin on filter. Simple
as that. There are no moving parts to mess up, it just ports the inlet and
outlet of the casting to the correct parts of the fliter. It is not removed
when a filter change is due.

As I mentioned earlier in this string, none of the filters regardless of
type; filters out more than 10-20 micron size material. Under normal
operation, as you have seen, this is fine, becasue the engines don't produce
metal like the older counterparts do.

If you want to keep the oil really clean, use an effective bypass filter
design with the std filter. They take the oil caotaminant level to 1 micron
or less.

Amsoil sells one, the Trasko-USA spin on design is another, there are
several others. The bypass design has been proven in diesel long haul
operations and heavy duty taxi service in New York (saw a study). But, under
normal driving and oil change intervals, do you really need it? That is for
each Vair owner to decide!
