The Gates PCV valve for 2017–2021 Honda CR‑V with the 1.5L four‑cylinder is a replacement crankcase vent valve intended for that engine. It vents blow-by gases and helps keep internal pressure balanced; replacing a failing valve restores the intended ventilation path and supports steady engine breathing and normal operation for the listed CR‑V model years.
