Review on πŸ”§ Dorman HELP! 42049 PCV Valve Grommet: Enhancing Engine Efficiency and Performance by Devin Girard

Revainrating 5 out of 5

GOOD TO CHECK FOR VACUUM LEAKS

Those rubber bushings are one thing to check. They become hard, the rubber deteriorates and sometimes gets into the engine. Many people simply swap out the PCV valve and plug it into the old socket. It's not good and they still have an air leak and wonder why the engine isn't working properly. It's much cheaper than OEM prices.

Pros
  • Exhaust and Emissions
