Designed just for racecars, Moroso's positive-locking valve cover breathers meet the rules for cars running 7.99 seconds and faster. They rely on threaded collars that mount on the inside of the valve covers, through the standard 1.22 in. opening, to provide secure attachment. They also have internal stainless steel baffling to keep oil and air separated. Jam nuts allow the breathers to be positioned in any way necessary to suit plumbing requirements, and Buna-N gaskets that are resistant to oil, alcohol, and race fuel are used to form an airtight seal. Mounting hardware is included.

On steep inclines/declines, engine oil flows to the rear/front of the engine and valve covers. At extreme angles, the factory PCV system allows engine vacuum to draw oil through the PCV valve and intake into the combustion chamber. This causes exhaust smoke from the burning oil and possibly hydro-locking the engine, as well as other internal damage. TeraFlex Jeep JK 3.6L crankcase vent system kits prevent oil from being drawn into the intake by engine vacuum while driving on extreme inclines. The kits add a second PCV valve to the front of the engine via an oil fill cap adapter and a T-fitting. Adding a second PCV valve at the opposite end of the engine ensures only air is allowed to enter the crankcase vent system regardless of engine orientation while off-roading. Features and benefits: * Prevents oil from entering PCV system and intake when on steep inclines/declines * Prevents burning oil/smoke, hydro lock, burnt starters, internal engine damage, etc. * Utilizes existing oil fill in valve cover to add a front PCV valve to existing system * Oil fill cap to crankcase vent adapter connects to existing PCV system via a T-fitting * Emissions compliant—the PCV function is unchanged * Retains OEM oil cap function and use * Easy install * Patent pending
