After a recent timing belt change, I'm getting a strange swishing
sound from the engine when the engine is cold - about once a second at
idle, increasing with engine speed. It disappears when the engine
warms up a bit. It's not the serpentine belt, as the noise is still
there when the belt's off. Nor is it the belt rubbing against the
timing belt covers, as I've tried taking those off too. Any
suggestions?

over tight in general? then any extra tight bits will make a noise

Sounds like it - though some makes of belts are just noisy anyway. Try
dribbling a little water onto the back of the cambelt as it goes round
and see if it shuts up. In the past I've found a tiny squirt of WD40 or
silicone spray will shut up a belt with no adverse effects.

does the new belt have a sticky patch on the back, where a manufacturers
sticker had been. could be when its warm the sticky reduces.
