RPM Drop From Nuetral to Gear

OK I think I'm getting somewhere. I swapped out the PV for a plug in the primaries and disconnected the PCV (and plugged the port). It fired right up and seems to run A LOT cleaner. I didn't have time to bring it up to temp before I had to leave, but I can tell it runs a LOT cleaner. It actually smelled like a hotrod should instead of just making my eyes burn. When looking at the PV on the bench, it appears to be fine. I tested it with a vac pump and it worked fine. I'm thinking maybe the gasket was leaking? Or maybe there just wasn't enough vacuum to keep it closed at idle. Either way, it's running better. I brought it up to 3500 rpm with any "popping."

Is it possible that the PCV was making it do that? All along I inadvertently left it connected. I guess I can reconnect it and see if anything changes.

I plan on getting it up to temp tonight and see how it runs. I'll keep you posted...
