UPDATE: got my car back from the mechanics today, I don't think they even bothered with anything except a quick "look". so I'm quite disappointed and I'm not even gonna bother with mechanics anymore, around here they're all lazy and don't do good work.

However I did get one piece of information, they said it's a possibility that the water pump or a part of it is making that noise. (they said they didn't have enough time to take off the timing cover to inspect it, but they had my car from 8:30am to 6:00pm.)

This may be true, and while I'm at it (if I can even find someone who can help me do this, hardly anyone knows about hondas in canberra) I might replace the timing tensioner as I have a brand new one sitting on my desk anyway.

Has anyone heard of water pumps playing up/failing and making noises like a spun bearing? :S
