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
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.

As it turned out, adjusting the tension on the belt just made things
worse - a whining noise from the (new) roller bearing. On
examination, both the (new) roller bearing and (new) tensioner
supplied by Euro C*r P*rts were leaking grease.
A whole new timing belt kit was fitted and the problem(s) vanished!
