well the problem is, either way if your timing is off a tad or the tensioner is bad youll have to go in there. Also, just curious , do your cams have holes on them? cause on my 93 integra when I did the belt the cams had holes in them to stick something in there so when you do the belt the timing doesnt move at all. I havent opened mine up on my h22 yet but im hoping it has the holes, my luck it wont lol. Also, does yours have a manual or an auto tensioner? if it is auto when they go bad the bearing goes all the way out so it tightens the belt more and that is what you hear, like a GRRRRRRR sound on deceleration..... if it is a manual tensioner then is it possible you tightened the belt too much? But the fact that you say it lost torque could mean the timing is off a tad because I do not believe you would feel a difference if power if the tensioner was too tight... either way, it sucks if you have to go back in there, but if you have to make sure to check/knock both things out at once, it sounds like its definitely related to one of those two.
