So I bought my equinox from a shop my finance works for. FOR 700.00 The timing chain had broke . It had 142,00 MILES on it. Still looks brand new on inside. Took it apart all the way to the head , pistols looked good so I replaced rods,lifters ect. Timing chain. Drove it about a month, and it started making a loud noise sounded like it was knocking, I could turn it off crank back up and it wasnt there . I could drive a few days no noise or it would do it 3 times b4 I would get to my destination . I didn't want to brake something so I parked it and started gooling.. So everything said the cam phazers where bad , every video I watched it was the same noise . We tested them like it said and they where both going bad. So 300.00 later we replaced them last night. And yet again I still have the same noise ...... Im beyond mad I've spent so much money , but I never quit so here I am
