Ok, I have had some dramas since getting a mechanic who was supposed to be a Honda specialist to replace my timing belt, balance belts, accessory belts and all front seals.

I now have this noise, like a pulsating squeeking noise. It is only at idle with revs under 900rpm. Anything more and the noise goes away and the car sounds normal.

I panicked at first and thought that the auto tensioner had failed so I got a new valve cover gasket and pulled the valve cover off to check the belt tension. Other than seeing the timing belt not centred on the cam gear, it looked fine. The belt was pretty tight, I tried to press down on the part of the belt between the cam gears and it was so tight it wouldn't even move. The tension on the exhaust side of the belt wasn't as tight as i was able to move it but was still pretty tight.

Is it possible for the autotensioner to be tensioning the belt too much? Is there a way to reset the autotensioner from the outside?

Also, I am thinking now that he replaced the accesory belts with aftermarket ones, it could cause the problem. It only makes the noise when the car is fully warmed up. Maybe this could be the cause. I guess I could start removing the belts and see if the noise stops.

But my main queston is about the auto tensioner, is it possible that it made the belt too tight?

Here is a video of the noise.

It only happens when the engine is warm. I have heard suggestions that the rubber ring inside the crank pulley may have been damaged and that is what's causing the noise.
