While looking at photos of CSX 2345, I noticed that the left and right valve covers appear to be stock stamped covers finished in chrome. Both covers appear to be the
oil filler/vent cap style. (no PCV port). I know PCV was just becoming a thing back then. Looks like both
oil fill caps vent off to their own puke tank mounted on either side of the engine bay. Was there a reason PCV was not used on this setup? Perhaps the flow of crankcase gasses at high engine RPM affected ENG/CARB tuning. Maybe the intake manifold didn’t have a vacuum port designed for this gas recirculation. I am prepping a 1965 289 for my FIA replica and am on the fence about replicating this valve cover vent set-up. Other than
oil puking into the tanks, is there any negative issue with not running PCV? Anyone have identification information for those caps and puke tanks on CSX-2345?
