It was asked:
> How important is a PCV valve?
The Roadsters do not have a PCV valve. They do have a closed
crankcase, with a hose going from the valve cover to a venturi built
into the air cleaner, but no valve.
In my opinion, there is little good, and much bad, to not leaving this
hose hooked up as intended. When connected, it provided slight
vacuum to the crankcase, helping to purge the corrosive fumes and
sludge-producing vapors that accumulate there. It's also a no-cost
emission control.
My opinion, obviously...
