Toyota Repair: PVC Value, interval, pvc

Question
How offend should it be replaced?

Answer
PCV valve.
Before they stick, or you're rings & oil take a dump with accellerated wear!


There is no replacement interval, but they should be checked atleast every 60,000 miles & replaced when dead. Normally I do them every 4 years on my cars. They're like $5-7 parts... Why wait till it fails? LoL!
