PCV valve replacement interval from Toyota is not documented, rule of thumb, every 30k miles
OEM Toyota GR86 PCV Replacement Kit
Brand:
Description: This kit includes both the genuine OEM PCV valve and the molded vacuum hose that connects directly to the valve, allowing you to refresh the complete PCV assembly rather than replacing only a single component. As these parts age, the PCV valve can become restricted or fail to regulate crankcase pressure correctly, potentially contributing to increased oil consumption, rough idle characteristics, and excess oil vapor entering the intake system.
