The Moroso PCV grommet set includes two GM-style valve cover grommets sized for PCV fittings, offering direct replacements for worn seals. Sold as a pair, these grommets provide a sealed interface between the valve cover and PCV valve or breather, helping to prevent oil leaks and maintain proper crankcase ventilation on compatible GM valve covers.
