Review on Enhanced V472 PCV Valve by Standard Motor Products - Optimize Your Search by Dean Pinheiro

Revainrating 1 out of 5

Do not buy! Two failed in a row!

The first valve I ordered didn't work. The check valve didn't work in either direction. When blown through the outlet end of the valve, the air flowed freely and did not stop. I ordered a replacement and it had the same problem. I know the correct operation because I checked the 15 year old valve that came OE on my Toyota and it REALLY blocked flow from the exhaust side.

Pros
  • PCV Valves, Breathers and Accessories
Cons
  • Zero
