By-pass oil filter?

[mbulriss]

Greg,

I see your point, but I don't recall that there is an oil path loop
there. As I recall, it is just a stub off of a pressurized oil galley
that Bird put a manifold on to allow for multiple temp/pressure
sensors. Check Ryan's picture at
http://www.ryanwright.com/tmp/sensor.jpg for detail. That's on a
frame rail near/above the starter area.

Bypass filter assemblies have *very* small restrictor orifices in the
intake area so that only small amounts of oil is allowed to enter.
The filters are highly restrictive to provide deep filtering down to
the 1-2 micron range. On a diesel, that means keeping soot levels down.

Based on docs in the blue box, there was one on my 83 that the prior
owner removed. I think it was one of the Purifiner tank types by
Puradyn that probably was in the way of the batteries based on mounts
I located. See http://www.puradyn.com for info.

The units I have are the newer spin-on filter design from Amsoil (see
http://www.amsoil.com/StoreFront/bmk30.aspx). Others make similar
units. Since I run synthetic oil, I really would like to keep the soot
levels down and keep it cleaner longer.

FWIW,
