How to find the right Automotive Replacement Emission PCV Valve & Breather Grommets AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Automotive Replacement Emission PCV Valve & Breather Grommets
- Size fit
- The grommet's inner diameter must grip the PCV valve or breather tube, and its outer diameter and groove must match the valve-cover hole A loose grommet causes a vacuum leak, lean codes and oil seepage.
- Material
- Choose oil-resistant rubber in place of the original material Grommets sit in oil vapor and heat, and the wrong rubber swells or hardens quickly.
- Replace with the valve
- Replace the grommet whenever the PCV valve is replaced Old grommets are usually hardened and cracked even if the valve looked fine.
Brands that matter
- Dorman: Wide range of PCV grommets for specific applications and in assortments.
- Standard Motor Products: PCV valves and matching grommets.
- Fel-Pro: Grommets bundled with some valve cover gasket sets.
What to avoid
- Reusing a hardened grommet with a new PCV valve
- Sealing a loose grommet with silicone instead of replacing it
