Retarded Catch Can Question
There's a Y junction behind the manifold that connect the passenger and driver sides together, then a SINGLE line runs beside the 2 4 6 8 injectors, into the PCV valve, and into the manifold.
The tube going from the front of the passenger side valve cover to the throttle body is called "the fresh air tube". It's at a higher pressure than the port where the PCV hose plugs into the manifold, so air is being forced into the crank case to *purge* the combustion gasses that leaked past the rings.
