A problem that I experience and I suspect for others is the fact that all crankcase vapors breath out into the atmosphere. This not only an environmental problem(severe) but also makes an oily mess under the hood and under the car from fumes escaping from the oil filler and lower crankcase vent. I am aware that their are retrofit closed crankcase breathing products available to address this and that they were standard as a first step to emission controls on later 300's. My question is if anyone in the club has looked at this closely and devised a clean looking and effective method to address this problem without compromising the stock appearance of the engine compartment. And if so could describe the method to do so. I believe that many of us would be interested in a solution. Would such an effort cost points in a judged meet or would it be treated as a safety(environment??) upgrade as tires or seat belts are? Speaking of this, how are disc brake conversions treated in judging? Roger Schaaf 300 B Calif [Non-text portions of this message have been removed]
