The original "breather" system on the '33 wasn't working very well.... On the San Francisco to Austin, Texas trip - I'd get little drips of oil from the filter - and it would blow back on "everything".
Since the car was being shipped back to Brizio's in SF for storage until we go out to drive it down for the LA Roadster Show.. I asked Roy to come up with a better solution. There's now TWO -8 AN lines (one from each valve cover) to a catch can mounted on the firewall - versus the ONE -6 AN line (from one valve cover) it used to be.
