*** Eliminates top end drain back oil from even touching the base gasket
*** For best results use with metal base gaskets
*** Tap the cylinder in the top end oil drain back hole with the supplied aluminum tap and install the PigTail® with about one inch left protruding to be inserted into the crankcase
