In the last couple of years I have replaced 2 timing chains. The first was a 1991 2l CS, non turbo with 110k miles. It sounded like ball bearings bouncing around in a tin can since the chain was touching part of the metal cover. Was not easy to tell if noise was the chain or from the camshafts but tended to be towards the chain end. The car had been driven for a year like this. The second, a 1993 CDE 2l LPT turbo with 140k miles did not sound quite as loud but since this was my car I was keen to sort it quickly. Once done, both cars were quiet once the oil had circulated and primed the tappets. The first took 14 hours, the engine under tray bolts were all seized and I was working from the Haynes book being new to the car. The second took 22 hours, the oil cooler pipes adding extra work - poor design putting pipes in front of the timing cover (oil and water) so job takes twice as long.
Easy ways to check for wear are to remove cam cover and if chain is worn will be slack between cam sprockets when both in timing position. When new will be tight. Also chain tensioner if removed will be fully extended (remove spring bolt first before removing).
