Breather and PCV Grommet Set

The Breather and PCV Grommet Set is a critical engine ventilation component engineered for Ford vehicles requiring precise crankcase pressure regulation. This kit addresses the need for reliable positive crankcase ventilation (PCV) system integrity, preventing pressure buildup that can compromise engine seals and gaskets. Designed for technicians and DIY enthusiasts who understand that proper crankcase breathing is foundational to engine longevity, this grommet set restores factory-specification airflow pathways that deteriorate over time.

Constructed from durable black rubber, the Breather and PCV Grommet Set features a precision 1.22-inch hole diameter engineered to maintain optimal seal pressure while allowing controlled vapor escape. The rubber composition resists oil saturation and thermal cycling, ensuring consistent performance across varying engine temperatures and operating conditions. This kit-format design simplifies installation by bundling all necessary grommet components, eliminating guesswork and reducing the risk of incomplete PCV system restoration that could lead to oil leaks or rough idle conditions.

Ford owners experiencing oil seepage around valve covers, excessive crankcase pressure, or PCV system rattling will find this grommet set indispensable for targeted repair work. The compact, lightweight design (0.11 lbs) fits standard Ford engine bay configurations without requiring adapter plates or modification. Installation is straightforward for anyone with basic mechanical knowledge—simply locate existing breather and PCV mounting points on your Ford engine block or valve cover assembly and press-fit the new rubber grommets until they seat firmly, creating an airtight seal that restores proper system function for immediate performance improvement.
