Ishino PCV Valve Grommet Replacement Seal

The Ishino PCV valve grommet (also called a PCV valve seal) is a replacement rubber grommet. It seats the positive crankcase ventilation (PCV) valve or breather fitting in the valve cover or intake. A good seal keeps the crankcase ventilation system closed, so vapors and blow-by gases are routed through the PCV circuit and not leaked out of the engine.

Key Features:

• Replacement grommet that restores the seal around the PCV valve or breather port
• Helps prevent vacuum leaks and oil seepage at the PCV connection
• Flexible rubber construction that fits snugly and absorbs engine vibration
• Made by Ishino, a Japanese engine seal and gasket manufacturer known for OEM-style replacement parts for Japanese automakers
• Direct-fit design for simple installation when the PCV valve or breather is serviced

Rubber grommets harden and crack with heat and age. A worn one can cause rough idle, oil leaks, or a vacuum leak. Replacing it with an Ishino grommet helps keep the crankcase ventilation system sealed. Select the child item that matches your application.
