I was Just curious, i noticed that air is acutally coming from my valve cover breather, is that right?? i thought air was suppoused to be sucked in from there fresh air for the crankcase and the pcv suppoused to expell the pressure to the IM?? or is this right?
thanks!

The IM creates a vacuum that sucks air out of the crankcase through the PCV valve. Is the PCV valve or hose clogged?

i just went to napa and bought a replacement for $10?? (not to brag.. but that's pretty pricey). anyways with a few trouble testing, i noticed that when it idle's air comes out of the breather valve.. but when i rev or open throttle air is sucked in. i then popped my brothers d15 del sol and took off his breather and when he idle's it's still sucking in air?, then i started to do a "test" fitted a small hose and taped it around the inlet of a vaccum cleaner and stuck it into the pcv valve inlet and turned it on, i then placed a pieace of paper near the breather valve and it sucked it in?? so doesn't that mean that there isn't any clogges?

thanks!

Post pictures of the hoses you are testing for air flow and which direction you see air flowing.

The breather in the valve cover usually blows out on my motors.
