But rather than having the more familiar type of <a href=\"https:\/\/www.carparts.com\/pcv-valve\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"PCV valve\">PCV valve<\/a>, some Asian makes simply connected a vacuum hose to the crankcase drawing air through a small orifice. Jeep Cherokee and Wrangler 4.0L do this, too, as does GM on some of their pickup engines.<\/p>\n\n\n\n<p>The issue with drawing crankcase pressure into the intake manifold is that a filtered vent is needed somewhere else in the crankcase to allow air to enter the crankcase, because a properly operating PCV system will pull more air through the crankcase than the blowby being produced by the piston ring blowby. Thus, if the PCV system is working properly, air will be entering the closure point, whether it be a filter in the breather or a closure hose connected to the air inlet tube between the mass airflow sensor and the throttle body.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>The issue with drawing crankcase pressure into the intake manifold is that a filtered vent is needed somewhere else in the crankcase to allow air to enter the crankcase, because a properly operating PCV system will pull more air through the crankcase than the blowby being produced by the piston ring blowby.<\/p>\n<cite><em>&ndash;&nbsp;<\/em><a href=\"https:\/\/www.carparts.com\/blog\/author\/richardmccuistian\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Richard McCuistian, ASE Certified Master Automobile Technician\">Richard McCuistian, ASE Certified Master Automobile Technician<\/a><\/cite><\/blockquote>\n\n\n\n<p>So where&rsquo;s the problem with PCV that it needs this sensor? Well, the PCV system can stop up sometimes because it&rsquo;s always processing steam composed of water, oil, and fuel, and that clogging can cause crankcase gasses to exit through the closure hose.
