Review on πŸ”§ FRAM FV391 PCV Valve with Enhanced Positive Crankcase Ventilation by John Ghattamaraju

Revainrating 4 out of 5

rattle version.

This is the "Thunder" version, that's what came out. After 225,000 miles it was really full. Replaced with the membrane supplied with the hose. I think I read on the forum that the rattle was replaced with a neck.

Pros
  • Exhaust & Emissions
Cons
  • Zero
