Funny you should mention oil filters. To support my car habit, I am in
the filtration business (mostly industrial systems) but some things to
think about. 180 mesh is much too coarse to be any use. 10 microns is
a good acceptable range on a closed system (where the oil continuously
circulates) but you should probably change filters at each oil change.
We use the Fram HP1's on the TR6 and TR8....on the TR8 there are two in
series. Parker Hannifin, through their Racor Division, markets the old
Oberg strainer (do not confuse filtration with straining). As a rule of
thumb, filtration is defined as solid liquid separation below 100
microns and straining, above 100 microns. How long was the filter in
that plugged? Filters are cheap and should be changed
frequently....like the mechanic says, "pay me now, or pay me later".
Remember that most spin ons have a by pass valve that kicks in about 10
pounds differential so that you do not starve the bearings. You can use
elements without a by-pass, but you risk starvation. Also remember,
that as you use the filter, it will perform better as it loads up. What
you want to avoid is running the deltaP so high the element (cartridge)
unloads. Buy an HP1 from Pegasus for the pressure side, and put a
Parker/Racor on the scavenge side and you should have plenty of
filtration. Just change them often. It is cheaper than an engine
rebuild. Bill Warner, H.C. Warner, Inc. First in Filtration Since
