Crankcase ventilation

On my new BBC, I am running a vac-u-pan system. The trouble is,the headers were ceramic coated before the kit was installed. So the kit was installed in the collectors. Mind you i never run the car with open exhaust even at the track so i guess its not an issue. however. On the street. i am wondering if i am getting enough draw through this system with closed exhaust? i was looking at installing 2 extra breathers on the motor, or 1 extra breather and a pcv valve?The motor is going on the dyno, and i will know how much vacuum the motor is making at that time. What is the correct way to do this?

no thoughts on this?

Sorry i have no idea what your talking about, or i would help

It should be installed at the collectors. Some times they don't work well with mufflers. Some guys just run hoses into a tank with a breather on it to allow the pressure out.

yes i have try them and if you get off it running the engine hard it would blow the sick out of the dip stick tube and blow oil out [it needed to find a vent] that was with a3inch ex have tired it with 4 inch to . it just dose not work that hot with a EX i just run open breathers
