It's a hydraulic tensioner. you can't overtighten them. first
thing's first pop the belts off and isolate the noise. it may be an
accessory. possible it's a tranny bearing but who knows. start with
the basics.
or could be one cam slipped when the tensioner was done. i've seen
it happen a few times.
