TIMING CHAIN

I HAVE A 1992 FORD BRONCO WITH A 5.8. I GOT A QUESTION ABOUT TIMING CHAIN PLAY, I NEEDED TO REPLACE THE WATERPUMP BECAUSE IT WAS LEAKING AND THE TIMING CHAIN GASKET LOOKED LIKE IT HAD BEEN SEEPING OIL SO, I PULLED THE COVER OFF AND NOTICED THAT ONE SIDE OF THE CHAIN IS TIGHT BUT THE OTHER SIDE OF THE CHAIN I COULD PUSH IN AT LEAST AN INCH OR MORE. DOES THAT MEAN THE TIMING CHAIN NEEDS REPLACING AND IF SO, I GUESS YOU CHANGE THE GEARS TOO. ANY HELP IS WOULD BE APPRECIATED.
