Crankcase compression: I have not read all the postings in this thread, I have not read all the engineering data. Has there been any discussion on crankcase compression ? All modern engines, at least the last 50+ years, Have some form of Positive Crankcase Ventilation. What is the thinking on this new engine ? I know I addressed it 30+ years ago on my own modified B engine with a PCV valve. All engines have a certain amount of "leakdown" Thanks, Rick.
