How do you plumb an oil catch can?

To plumb an oil catch can, first, identify the intake system's positive crankcase ventilation (PCV) line, which typically runs from the engine to the intake manifold. Disconnect this line and connect it to the inlet of the catch can. Then, connect the outlet of the catch can back to the intake manifold or a designated vacuum source. Ensure all connections are secure and that the catch can is mounted in a location that allows for easy access and maintenance.
