Welcome to the forum, hotrodfeguy! That's cool that you recognize your mod. My question is why leave the PCV connected if you have a catch can connected to the VC and Air Cleaner? |

I didn't do a catch can I just fixed the baffle under the VC and flipped the rubber tube so the oil wasnt falling right into the middle intake runner. The catcg can looks like the wtg. |

Because the top vent in the TBI hat only provides a very small amount of vacuum, not enough needed to properly vent the crankcase pressures. It's a vent before the throttle body butterfly. The port that the PCV is hooked into draws a deep, powerfull vacuum as it is after the throttle body. The jiggle valve inside the PCV valve must also function correctly, thus the reason why I said put a new one on when doing a catch can mod. |
