Rough Idle or PCV System Problems?

Replace Your Failing EA888 Check Valve Before Vacuum Leaks Get Worse.

The factory cylinder head breather check valve is responsible for regulating crankcase ventilation flow and maintaining proper one-way pressure control inside the PCV system.

Over time, the internal valve mechanism can wear out, stick, or fail due to heat, oil vapor, and carbon buildup.

A failing check valve may cause:

✔ Rough idle
✔ Vacuum leaks
✔ Excessive oil consumption
✔ Check engine light
✔ Whistling noises from PCV system
✔ Poor crankcase ventilation
✔ Oil vapor leakage

This OEM-style cylinder head check valve is designed to restore proper PCV system operation and stable crankcase pressure regulation.
