Excuse the hi-jack......suppose someone has a motor with a flat tappet cam that has been sitting for a while.....it was a driver for a while. I realize that the break in of cam/lifters is done but what should be done other than yank the dist. and spin the pump up to get oil every where again? Should a zinc additive be used just as a safeguard?
Threads like this convince me that a roller cam will be used when I get around to my motor some decade....
