PURPOSE: A PCV valve for a car engine is provided to reduce noise when a valve body moves back caused by static pressure because a buffer member of plastic materials impacts with a body of the plastic materials. CONSTITUTION: A PCV valve for a car engine comprises a body of a head cover side(110), a nipple of an inlet manifold side(120), a valve body(130), a spring(140), and a washer(150). The PCV valve for a car engine is installed between the inlet manifold side of a car engine and head cover side. The nipple of the inlet manifold side is connected to a front end part of the body. The valve body is installed inside the body. The spring elastically supports the valve body. The washer is installed between the body and the nipple. The buffer member(160) of the plastic materials is formed in one behind the valve body.
