The Moroso GM valve cover PCV grommets come as a two-pack and accept fittings with a .095 inch outer diameter. These replacement seals restore the valve cover-to-PCV interface, helping to prevent oil seepage while preserving crankcase ventilation function. The pair is intended for GM valve covers that require a .095 inch grommet and routine seal replacement.
