Abstract
In a combustion engine, an exit stream of blow-by gases follows a fluid pathway through an oil and air separator and a breather filter, the oil and air separator including a first housing including a central chamber therein, the central chamber divided into a first outer portion and a second inner portion by a barrier; a filter material disposed between the first outer portion and the second inner portion; a cap directly coupled to the first housing, the cap including a first lumen therethrough, the first lumen including a first end disposed at the second inner portion; and a coupler removably coupling the cap and an extension portion including a second lumen therethrough.

1-13. (canceled)
A method of controlling air flow through a PCV valve body comprising selecting a port from a group of ports, each port of the group of ports including a lumen therethrough of a diameter different than the lumen diameters of the other ports of the group of ports;
- and positioning the selected port at a fluid pathway extending through the PCV valve body to provide a desired size lumen diameter in fluid communication with the fluid pathway.
A method comprising providing a positive crankcase ventilation (“PCV”) valve kit including:
- a group of ports, each port of the group of ports including a lumen therethrough of a diameter different than the lumen diameters of the other ports of the group of ports;
- and
- a valve including a first end and a second end and a body between the first end and the second end,
- the valve first end including a first portion for removably coupling to an intake manifold port;
- the valve second end including a second portion for removably receiving a port selected from the group of ports;
- and
- the valve body including a fluid pathway extending between the intake manifold port at the valve first end and the port selected from the group of ports and received by the second portion.
