first off was the cam break in period done? i also havebeen told the first 3k miles of the life of a new engine there should be no constat high speeds ie anything over 40 mph iif you do the ring will never seat propley. sounds to me that the cam is gone and or the proper break in period wasn;t done and the motor is just trash because the rings did not seat right ihope you figure it out reall easy
