How can I tell if my timing chain is too slack?
Listen to the action of the rocker arm tappets. If they seem loud, move the stethoscope further down the valve cover and listen again. Move a few inches at a time. Listen for noisy lifters.

What are the symptoms of a bad timing chain?
Common signs of a faulty timing chain include engine misfires, metal shavings found in the oil, and rattling sounds from the engine while idling. Since the inception of the internal combustion engine, one constant has remained – all of them have a timing chain or timing belt.
Why to change timing chain?
Improved fuel economy – Changing the timing chain is also going to improve the gas mileage in your car. A new timing chain will ensure that the crankshaft and the camshaft are working perfectly in unison. This ensures that the valves on the engine are able to deliver great combustion. In the end, you will save a lot on fuel costs.

Once your timing chain gets stretched out it’s best to go ahead and replace it as it will have more slack in it than a brand new one would and it’s likely that your timing chain is old and could be close to breaking. Usually, problems with the timing chain tensioner or engine oil levels will cause the timing chain to stretch.
