For those running breathers on valve covers...

What are you using to block off the old PCV port? I removed the gromet and tried using a rubbert radiator plug that expands as you tighten a bolt.. it works for awhile but then loosens and pops out.

What is the best way to do it?

I have breathers on both covers with lines to a vented breather.

I put a freeze plug in and siliconed it so there would be no leakage. I use two breathers one for each valve cover.

Plastic elbow out of the gromet, heater hose to a catch can. May as well make use of it for extra ventilation.
