H22 Timing Belt Autotensioner Noise

Last year I had my first timing belt done by a locally respected (not Honda) mechanic. I immediately noticed a whirring noise that made me think the belt was too tight. He assured me was nothing but a symptom of a stiff new timing belt. The noise did decrease with time until last Spring when the water pump housing fractured causing a timing belt catastrophe that nearly ruined my engine. I towed to another mechanic that specializes in Japanese cars and he again replaced timing belt, pump, etc (another $700). Ran nice and quiet after that.

My oil light when on a few weeks ago and I pulled over to find no oil in the engine. It was coming from the front of the engine and it took 8 quarts to get the car home 20 miles away. Anyway, I wasnt going to another mechanic - this time I fixed it myself. It was of course the front balance shaft seal which was dangling on the shaft that had no seal retainer on it (Japanese car specialist eh?). I replaced this, the main crank and both cam seals, added the seal retainer, cleaned everything, recompressed the autotensioner (no I didnt do the manual swap) and reinstalled both belts a la the Helms manual. All this during the coldest week in this Minnesota Winter and in an unheated garage (a stud eh?).

Anyway, the car runs great but is making that @#&!%#% whirring noise again. Its not as bad as before but it makes me wonder why. I reused the autotensioner that was on there since it was relatively new and since the car was quiet with this one. Did I (not a mechanic) put the balance shaft belt on too tight? Nothing appeared unusually tight compared with timing belt tension videos I saw on Youtube. Should I re-open it and try loosening it?

Manual Tensioner last for ever.. Auto's poop out @60-65K ( and Honda Says it will last a life time!)

although the manual tensioner may seem like a good idea you need to make sure you get all the parts needed and its a load easier when the engine is out of the bay..

the noise your hearing may go away.. how did you determine you had enough tension on the belt??? if your tensioner is failing it will make your engine sound like a diesel.. (belt hits the Valve cover at a high rate of speed).. get it checked out buy a honda tech or it could lead to some damage in the long run..

there is a DIY floating around on the web for the conversion and a link to buy all specific parts..
