The Cobra I once owned was built for street and track use with no PCV and a catch can plumbed to the closed valve covers. I changed the oil and emptied the small amount in the catch can before each track event. Other than negligible damage that may have been done to the environment, I saw no disadvantage to that system. Had it been a car that saw 15,000 miles per year, my answer may have been different. |
Tommy, Appreciate the feedback. My plan is to build a car for street and track use too. If I go with the Webers then PCV won’t/can't be on mine either. Don’t mind the more frequent oil changes unless it’s my RAM pickup.
