No PCV valve?
I recently put my new valve cover on and it came with those blue AN fittings and I didn't know how to use my pcv valve with those AN fittings so I just removed it and I'm using my boomba check valve, car seems to be running fine but I'm not sure if it can cause any potential problems.
Here's my current catch can setup...
Catch can, Check valve, passenger side valve cover
Catch can to TB
drivers side valve cover to to aem intake or thinking of using a breather for the drivers side valve cover.
