theres no need imho to slacken off the cam pulleys when doing a belt change on these engines! timing pin keeps the crank set and the bar in the back of the cams keeps them set. once its turn the engine over a few times, refit the crank pin and rotate the crank till it contacts the pin. if you can slot (or near as makes no difference) the bar back in the cams its timed up perfectly!
