On the L5P Duramax, the CCV system is integrated into the valve cover and connects to the intake air horn. This setup uses Bernoulli’s Principle to create vacuum and route crankcase gases back through the intake for reburning — a requirement for emissions compliance.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eOver time, especially in higher-mileage diesels, excessive blow-by causes oil vapors to be carried into the turbocharger inlet. The engine consumes this oil, which can lead to carbon buildup and reduced efficiency.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWhy Upgrade?\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe factory CCV system on the L5P is made of plastic and is known to crack or fail over time, allowing boost pressure and hot charge air to enter the intake system improperly. Additionally, the OEM system is non-serviceable — if it fails, the entire driver-side valve cover must be removed, requiring fuel line and injector removal, often totaling 6+ hours of labor.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis upgrade kit eliminates that problem entirely and offers several key improvements:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eKey Features \u0026amp; Benefits:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eDirect replacement for the factory CCV system\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDurable construction — eliminates weak factory plastic prone to cracking\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eIntegrates dual passive oil separation stages\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eUses proven differential drop technology from marine and heavy-duty diesel applications\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eHelps keep intake components free of oil and carbon buildup\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eRelocates oil fill port to the front of the engine using a billet standpipe\u003c\/span\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eTall enough to clear engine accessories\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMakes filling oil easier, especially with gallon jugs\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eSeparates oil fill from CCV system for improved safety and cleanliness\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eReduces oil ingestion into the turbocharger and intake manifold\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eNo tuning required — completely passive system with no moving parts\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Hill's Diesel","offers":[{"title":"Default Title","offer_id":47682413035738,"sku":null,"price":265.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0769\/1819\/4394\/files\/IMG-1201_480x_d7d4eb46-565b-4288-aa5e-c617ab6e95c3.webp?v=1773756802","url":"https:\/\/hillsdiesel.com\/products\/l5p-17-25-billet-ccv-reroute","provider":"Hill's Diesel","version":"1.0","type":"link"}
