PCV Valve Installation and Repair Tips for 1989 Mitsubishi Sigma
- Q: How does the PCV Valve in gasoline engines prevent combustion blow-by gases from entering the atmosphere on 1989 Mitsubishi Sigma?A: The Mitsubishi gasoline engines have a closed PCV system whereby the cover has a valve that regulates air intake into the blow-by gases. Have inspected and cleaned every five years or 50,000 miles (sooner, when rough idle). Unscrew and verify the PCV, vacuum/hiss/free airflow; change when defective. Install without cross-threading or over tightening.
