Bub's right and you wouldn't believe what I have spent on the dyno with PCV's. The good news is they work. But there's a lot of buts and I'm not going to tell all because my engine builder would kill me!. But I will share that not all PCV's are created equal! That's why there are so many part numbers. I bought from the discount stores and the OEM's. I looked at late model (emphasizing the low drag piston ring models) equipped on small blocks to big blocks to the older stuff. There are more effective ways to find HP, this is just one way to get there.
