My 2.2 with 70,000 miles is pretty quiet, don't recall hearing a ticking but of course now I will!The timing chain on GM ecotec engines has always been loud, even this newer 1.4T version. Think this one is loud you should hear the old 2.2 "eco-tick" when the oil was cold, sounded like a diesel engine.
A timing chain will always make more noise than a belt, but I prefer the noise to having expensive maintenance & possible failure of a belt.
