Dorman’s OE FIX redesign uses an improved retaining feature and arrives as a complete installation kit, saving time and reducing the chance of repeated failure when compared with the original equipment piece.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the redesigned manifold prevent PCV valve issues?\u003c\/h3\u003e\n\u003cp\u003eThe 615-380 replaces the original housing with a redesigned internal geometry and a retaining pin that secures the PCV valve in place. This change helps keep the valve correctly seated under engine vacuum and thermal cycling, reducing the risk of valve migration that can lead to oil consumption.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated retaining pin to lock the PCV valve position\u003c\/li\u003e\n  \u003cli\u003eReinforced mounting points to withstand vibration\u003c\/li\u003e\n  \u003cli\u003eEngineered flow paths to maintain correct crankcase ventilation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat comes in the complete installation kit?\u003c\/h3\u003e\n\u003cp\u003eAlong with the intake manifold, Dorman ships the 615-380 as a full repair kit so you receive the necessary gaskets and seals for a proper install.
