GM PCV Valve – CV736C – Correct for 1966–1970 GM Models

A properly functioning PCV (Positive Crankcase Ventilation) valve is critical to engine health. The PCV valve regulates excess crankcase vapors and prevents harmful gases from contaminating engine oil. A worn or malfunctioning PCV valve can lead to sludge buildup, reduced performance, and even engine failure.

This replacement CV736C PCV valve is correct for many mid‑1960s to early‑1970s GM vehicles equipped with small‑block V8 engines. Perfect for restorations or routine maintenance.
