Are you tired of your sheet metal tappet cover leaking oil ? Our billet cover will eliminate the oil leaks and look good in the process ! Unlike most competitors billet tappet covers we DO NOT use silicone to create a seal at the block. Our covers have an o-ring groove machined into the back and includes a pre-installed o-ring to ensure a perfect leak free seal ! Our covers have been tested to fit and clear VE, P-Pump and VP style pumps ! These covers come threaded 3/4" NPT and ready to accept whatever style lines you choose to use.
