filtered oil filler cap

Answer me this. I've seen some people running 2 pcv valves. One in each cover.what does that do? Does it have any effects on the motor?

it could be an attempt to draw out the pressure built up, some race cars have a pump to draw out the pressure so the rotating assembly will spool up quicker

So someone could run 2 as long as they have a vent somewhere on the motor.

the G body came with 2, the pcv on one side and the breather that went to the air filter container on the other valve cover

Okay so when I got to work today I was letting the boy I work with read the post so far because there is some interesting info posted. He informed me that his uncle was running 2 pcv valves that was connected to a catch can before it went into the carb. He had a vented oil fill cap kinda like the one I have. Could I do a set up like that on mine?

PCV valves come in different flow rates. It isn't uncommon for aftermarket replacements to have more flow than OEM. You want to look at the letter stamped on the valve pintle. F stamped PCV valves flow more than the ones marked E.
