PVC/Breathers/Oil Fill ?? Confused!!

[dakman]

I'd like to see a pic of the T-connection you are talking about for the trany and PCV. My thoughts are... if you are only tapped into one runner on the manifold and supplying both the PCV and trany vaccumme from it then maybe when you get on it and the trany is shifting you may be starving the PCV system badly leaving the crank case pressure no where to go. The PCV should tap in at the base of the carb so it has a continous vaccumme from all runners below the throttle plates. I would seperate the trany and PCV and ensure they are on different sources. Just a guess?

Based on your picture...another way to make the PCV system more efficient would be to move your PCV to the opposite end of the valve cover opposite the breather so it has to cross feed the crankcase. Maybe having the PCV drawing out at the back of the engine where the breather is also located is allowing the front end of the crank case to build higher pressure.... again just a guess.
