Review on πŸ”„ Optimized FRAM FV401 PCV Valve for Positive Crankcase Ventilation by George Miller

Revainrating 5 out of 5

Exact replacement for the 2000 Tundra 4.7 V8

The check valve moves freely as it should and it fits the 2000 Tundra as intended, it probably vents necessarily the crankcase. The bar wasn't high, but it's better than the old dirty one that was sealed.

Pros
  • The PCV valve was the first of the exhaust system components to be fitted to production cars
Cons
  • unreliable
