The ACDelco 10198949 is a genuine OE replacement PCV (Positive Crankcase Ventilation) valve grommet designed to provide a secure, leak-free seal between the PCV valve and the valve cover or intake manifold. This essential component prevents oil leaks and maintains proper crankcase ventilation system function.

Key Features:

• Genuine ACDelco OE quality rubber grommet
• Prevents oil seepage around PCV valve installation point
• Resistant to heat, oil, and engine chemicals
• Ensures proper seal for effective crankcase ventilation
