bigbreak_2000 Posted November 4, 2010 Share Posted November 4, 2010 (edited) I'm planning to install the Cusco catch can. The can has two connectors. Couple questions on maintaining a closed loop system: 1) is it best to install the catch can between the crank case and PCV valve on the intake manifold, or install it on the "other side" of the system , that is between the valve cover (after flame arrestor) and air duct pre-throttle chamber? I'm not sure which side of the system will be more prone to pushing oil and fumes back into the manifold. My thinking was best to place it between crank case and PCV valve, but seems from what I read on most other forums folks install it on the line between the valve cover and intake. BTW engine is a NA 3.2L Stroker, newly built, and I still need to meet emission requirements which calls for a visual inspection that PCV system is in place (therefore need to be a closed loop setup) Edited November 6, 2010 by bigbreak_2000 Quote Link to comment Share on other sites More sharing options...
