So I bought a used cam from someone off of a fox body Facebook forum. The cam looks ok to the eye but I got it installed on the car and primed the motor and lifters with an old distributor that I made into a priming tool. Long story short after torquing down the rocker arms to spec some of the rockers are pretty loose still. I can slide the stock cam back in it and do the same process with priming and torquing and the rockers are nice and tight like they should be. Is it possible that I got sold a worn cam?
