Anyone ever heard of an "Envalve" It's suppose to take the place of a PCV valve. They claim it reduces or completly eliminates blow by. I don't completely understand it. Is it another As Seen On TV flop or is it for real. I'd like to try it on something but I'm not giving up $50 of my hard earned money.

Nothing completely eliminates blow by. Blow by is leakage that goes past the rings in every cylinder, Engines don`t acheieve 100% sealing, some have gotten close though.

Ya that's what I thought about this valve. So if you are getting a small amount of oil smoke from your valve cover breather and this can be caused by worn rings how come there is no smoke ever coming from the exhaust pipes and compression is running 150 to 160 across the board.
