How often should you replace a PCV valve on a 01 tahoe with 200k miles?

Answer 1

For a 2001 Tahoe with 200,000 miles, it's generally recommended to replace the PCV (Positive Crankcase Ventilation) valve every 30,000 to 50,000 miles, or as part of routine maintenance checks. However, if the engine shows signs of issues such as rough idling, increased oil consumption, or excessive engine pressure, it may be wise to inspect or replace the PCV valve sooner. Regular maintenance can help ensure optimal engine performance.
