Please advise…Timing belt tensioner go bang. (18 Viewers)

I think whoever tighten those two bolts at the tensioner torqued too hard and was in severe strain and eventually both snapped. I don't think the belt can put that much pressure on the adjuster bearing arm to push the tensioner out of it place by snapping the two bolts. Your tensioner is still in one piece. Only broken parts are the two bolts. Do you see any markings on the tensioner?

It snapped the bolts, something forced it out from where it was.

Which is why my guess is they weren't tight when installed. If those bolts were torqued down i highly doubt they both would just shear like that. Even if the tensioner pulley failed. Thats the "loose" side of the belt.

Well right/passenger (even cylinders) bank is out of time. Coincides with the codes I got. Belt is perfect. I bought a bore scope and leak down tester to check cylinder health after this but everything looks fine. That was my first big job so maybe I did forget to tighten or over tightened. Lasted 68k miles at whatever rate.
