When the gaskets on the original equipment variable valve timing (VVT) spool valve fail on VTEC engines on certain Acura and Honda vehicles, the dealer only offers a complete, costly valve assembly as a replacement. But when the cause of the leak and valve failure is simply the gaskets, why buy the expensive entire assembly? This Dorman OE FIX VVT spool valve replacement gasket assortment is designed to save labor time and money by enabling the replacement of just the failed gaskets, saving unnecessary expense, helping to restore engine performance, and eliminating oil leaks that can land on and destroy the alternator.
