This one is for a V8 using the OEM sr20det pcv flow:
1. if possible, use only 1 check valve. "More checkvalves is worse, not better" I say that from common sense. Always use the minimum equipment to minimize failure of equipment.
2. Select hose diameter carefully, adjust with no additional containers. Less crankcase volume overall means higher response to vacuum, more effectively/effectiveness of vacuum signal.
3. Select orifice diameter "on the high side" as opposed to the entire hose. Account for potential flow and sludge with hose diameter
if necessary. This depends on power and maintenance interval.
making diagrams:
try to keep flow all the same direction
make sure its obvious which side of the air valves you are on, and where it is
