no its not. loose or worn valvetrain has a distinct sound to it. Like tapping, or ticking, it may also get quite loud in very worn out valvetrain. Loud knocking usually comes from the major rotating assembly (crank, rods, pistons, ect..). They are very different sounds. Best way to find out where its coming from is use a piece of 2 by 4 (about 12 inches long) and hold one side against the engine and put your ear against the other. Use that to trace to where the noise is coming from. U would be suprised how much u can hear.
