I need to make myself get on my carbs and give Gene at M/E Wagner a call too. He and his son Matt (the engineer) are GREAT on the phone and via email with tech support, and the owners manual is EXTREMELY helpful and detailed too.
Right now both of the M/E Wagner PCV valves (one on my 440+6, one on the Pontiac 421 Tripower) are set to "fixed orifice" mode because I've never taken the time to tune them. Their PCV valve fixed the problem that only developed after I changed the stock valve covers to my beautiful krinkle black aluminum fabricated MOPAR valve covers and installed a PCV valve "that fit". All of a sudden I had oil leaks and at highway and race track operations oil spritzing/leaking out of my breather. The M/E Wagner PCV valve fixed that!
I can recommend it to EVERYONE whether or not you have any problems with the PCV valve you have now, this will take you to a higher level of performance all around!
