air/oil separator group purchase

[Brett Dikeman]

Folks,

I'm working on a possible group purchase here and wanted to gauge interest.

As many of you know, a lot of oil manages to make its way into the
intake system through the crankcase breather system on the I-5 20v
turbos, despite the restriction valve...this oil causes a multitude
of problems, particularly in chipped cars:

-reduced intercooler efficiency from oil coating
-idle stabilizer valve gumming, throttle gumming
-deposits on valves, combustion chamber surfaces
-O2 sensor and catalytic converter fouling

While one can install a catch can with a washable filter and vent to
the atmosphere, this is not emissions compliant.  One could also
install Total Seal gapless rings to all but eliminate blowby, but
such an upgrade isn't exactly easy to install :-)

Far as I can tell, the best solution is an air-oil separator.  I've
contacted one company, Stef's Fabrication, which makes such a unit,
to see about pricing, sizes/connections, etc.  No doubt one of their
questions, eventually, will be "how many units?"

So, if you're interested, please drop me a line(do not cc the list(s)
for "me too" emails!) and let me know if you'd be interested in such
a widget.  I'm taking a rough guess that pricing will be right around
$100.

   If you can handle a screwdriver without stabbing yourself, you
should be able to handle installing this thing.  Only hardware
required should be two short lengths of hose the same size as the
crankcase breather hose up by the restriction valve(that 90 degree
thing), two plastic or metal sleeves to join the two, and something
to attach the separator to, say, the old windshield washer mount on
200q20vs(not sure about where S4/S6 owners would put it, I'd have to
study a few engine compartment photos.)

Maintenance would probably entail occasionally draining oil out of
it(there is a draincock on it) and maybe once a year washing out with
simple green or somesuch.
