[QUOTE="chips90, post: 15496, member: 3561"] Hello! I recently purchased a 2015 Chevy Equinox with the 2.4 Ecotec and AWD. The car has a little over 40k miles on it and everything looks like new. The only issue is that when I did the oil change ( second day after purchase ) the oil was black and thick... I replaced the oil with 5w30 Valvoline synthetic dexos and a high quality oil filter. I know the ecotec is known to have some issues with the timing chain tensioner when the engine is run with dirty oil. The only way to tell if the timing chain is loose from my understanding (without taking the engine apart) is to listen the engine while starting when cold - it does make a bunch of noise when is starting cold but I can't tell if it's normal or if it's a issue... The car doesn't have any OBD codes or pending codes for that matter. My question is, should I be worried about the timing chain ? Are there going to be some signs if it's on it's way out? [/QUOTE]
