It sure is fun to see the Rockets, EZs, Glasair IIs etc. going around
the pylons at the Reno Air Races.
With all the new composite racers coming on line, we might not see the
"conventional" sport planes much longer.
Is there any chnace a Fixed Gear category would be added to the Sport
Class at Reno?

The really "older" cars vented direct, no PCV. no catch bottles, it was a
line that ran down under the car to the road surface from the oil filler
neck. (No, Virginia the really "older" cars didn't have oil inlet caps on
the valve covers. (but some did have "breather" caps there).
Most RV's, Rockets have a forced air intake systems, this IMNSHO, would
produce opposing pressures. Vented air trying to get out, forced intake air
trying to get in. Unless you install a restrictive device to eliminate
backflow.
Use the KISS method, (Keep It Simple Stupid) run the vent line onto or into
the hot exhaust and burn/vaporize the yuk stuff. Build as fancy a connector
as required to keep you happy just make sure you don't reduce the size
and/or restrict the flow.
Why I even know why Harley riders wear black.....The "older" Harleys had a
chain oiler (we called it a spit tube, it was powered by venting gases) that
sprayed oil directly onto a spinning drive chain, which then flung the oil
everywhere & the oil spots didn't show so bad on black things. They also had
"spark retarders" & "kick starters". If you didn't "retard" the spark you
soon found out what the "kick" in kick starter meant.
EE...Gads, I think I just gave away how many years I've been walking
around on the planet. KABONG 8*) Do Not Archive (GBA & GWB)
