のＰＣＶ装置。[Claims for Utility Model Registration] (1) In a PCV device having a blow-by gas passage leading from the inside of the crankcase to the intake system, the blow-by gas passage is provided with a filter for separating oil contained in the blow-by gas, A bypass valve is provided in the blow-by gas passage in parallel with the filter in the flow direction of the blow-by gas, and opens when the pressure on the upstream side of the filter increases, bypassing the filter and guiding the blow-by gas to the downstream side. A PCV device characterized in that a bypass valve is connected to an alarm device that detects an opening operation of the bypass valve and issues a signal. (2) The PCV device according to claim 1, wherein the bypass valve is a valve having self-holding means for maintaining the open state once the bypass valve is opened.
