See that's the thing, it's a 2010, already had the most recent tensioner, I even reinstalled a new one along with everything else.
I don't know where to turn other than the cam phasers Because everything is new besides them, except when you're at idle, they are not even being activated correct, and if that's correct how can they cause chain slack.
Everytime you try to research troubleshooting the cam phasers not the solenoids, you always get bad cam phasers for fords, never a gm ecotec.
