back to needing one for both sides or just the drivers side...what made you go both sides?

BRENSPEED

Typically when you only run one that blow by tends to move over to the other side, so we recommend running two or a breather on the other side to eliminate all blow by oil from being burnt up.

You mean running a breather on the drivers side valve cover? Otherwise you'd be sucking in unmetered air through the crankcase.

BRENSPEED

When you run the breathers you have to cap off the opposite end so that unmetered air doesnt escape. So, the breather goes on the valve cover end of the PCV system and the cap goes on the opposite end. This works the same for the driver or passenger side.
