DP Customs L5P Billet CCV System

The DP Customs L5P CCV System is the perfect solution for enthusiast who want to clean up their engine bay and prevent unwanted oil from entering the turbocharger.  The factory CCV system has several flaws which include; housing cracking, boost leaks, inadequate oil fill location, and hot air temperature recirculation. All of these issues are resolved with our system while also reducing crankcase pressure.

Our unique design comes preassembled for a quick install. After removing your factory system, simply install the new included GM gaskets inside the billet CCV block and secure it with the included M6 bolts. This kit utilizes the factory oil fill cap and locates the fill neck in a perfect location for services. If you need a shorter fill neck, we have that option for you too! Unlike our competitors, The DP Customs L5P CCV Kit has been proven to STOP oil from exciting the motor and ONLY allows clean air back into your turbocharger or to the atmosphere on competition vehicles. No need for silly catch can band-aides, simply bolt on and know that your motor is breathing properly and NOT leaving oil puddles in your driveway.

DP Customs recommends using "high flow" AN fittings ONLY. 90* AN fittings (IE: -12ORB to -12AN) may reduce ID and restrict crank case pressure which can cause oil to be "pushed out". Motors with excessive amounts of crankcase pressure may still pass oil through the DPC CCV System.
