According to the present invention, an apparatus for monitoring dampness of blow-by gas comprises: a differential pressure sensor installed at one side of a cylinder head, and measuring differential pressure between pressure of a crank case and atmospheric pressure; and a control unit accessed to the differential pressure sensor, and formed to determine whether there is dampness of blow-by gas after comparing the differential pressure measured by the differential pressure sensor and a threshold. The differential pressure sensor can be installed in a position communicating with a blow-by gas chamber of the cylinder head. 본 발명에 의한 블로바이가스 누기 모니터링장치는 실린더 헤드의 일측에 설치되고, 크랭크케이스의 압력과 대기압의 차압을 측정하는 차압센서; 및 상기 차압센서에 접속되고, 상기 차압센서에 의해 측정된 차압을 이용하여 임계치와 비교한 후에 블로바이가스의 누기 여부를 판단하도록 구성되는 제어부;를 포함하고, 상기 차압센서는 상기 실린더 헤드의 블로바이가스 챔버와 소통하는 위치에 설치될 수 있다.
