🧩 What the 326‑4689 OCV Element Is

This part is a crankcase ventilation filter element designed to remove oil mist, soot, and blow‑by contaminants from the crankcase breather system. It helps maintain clean crankcase emissions, protects turbochargers and intake components from oil contamination, and supports compliance with emissions standards.

OCV elements are essential in modern diesel engines because they prevent oily vapor from re‑entering the intake or being vented to atmosphere.
