By-pass oil filter? - mbulriss - 11-08-2008 06:55
Does anyone have one of the old by-pass oil filter set-ups that can
verify where Bird tapped into for the feed and return lines? I have a
couple of new bypass filter set-ups in the garage that I may add to
help keep the oil clean. These are newer style bypass units with
spin-on filters, not that old tank unit with the messy internal filter
cartridges, like were installed as an option in some of the old Birds.
I was looking at the Bird while searching for that air suspension
problem. It appears that I can use one of the spare ports on that oil
feed manifold that they were kind enough to build in to install the
oil pressure and oil temp sensors and aux rear oil gauge (like Ryan
just added). From there, it seems like I can tap into the output side
of the bulk oil fill line for the return. Since the oil manifold and
they bulk oil return line are close to each other, it would make the
plumbing quite easy. It will take longer to find the hose and
plumbing fittings than the actual install. Harder part is figuring
where to mount the filters.
Anybody see any problems there?
Whew, I starting to feel like the Kurt/Curt crowd... LOL!

Mike, my only concern would be if the oil path that you open
for 'in' filter looped the new path you mapped as the chosen path of
least resistance, what hapens down the line with functions that
path 'was' intened to oil with the gpm lost to the new path of
least resistance? things might not get oiled untill the filter clogs
up. Once clogged a little, the filter will be of no value because
it would then just be bypassed to the old path now having least
resistance. IfItABDFI?

Mike, I believe mine is mounted on the curb side of the engine with a manual oil sending gauge. You are correct about those old ones being messy.

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,

No problem with your supply point Mike. Just make sure you have an
unrestricted return to the pan. If you connect to the bulk oil fill
line, you will have a problem pressure reversing your filters when you
go to put oil in the engine. Possibly inserting a check valve, you
could get away with it.
There might be a port on the engine similar to the dipstick location
that would allow you to dump into the pan. There was on the 6V92.
Ask Ernie, because I had one on that engine.
