The problem is not the people installing the seal! Its somthing else. the motor did not leak in 440 form it started after the stroker was installed and it had a rubber seal in it befor. the crank is a mopar crank . I have not tried a rope seal yet,that is on the list . The way it leaks i find it hard to belive its the cam plug but hey at this point Ill belive any thing. THANKS. NICK
