106 gti engine rattle

Hi, this is my first post.

I have a 106 gti that the engine rattles from time to time, normally
after the car has warmed up - it is a whining rattle that comes from
the timing belt area/16v box. Possibly, but not definitely air
escaping. The car is running fine, I had the timing belt changed about
10k miles ago.

I have had a mechanic take the cover off the belt and have a look - he
says everything is fine in there. What else could be making this
noise?

Any replies much appreciated - I am worried about my cam belt going
then the engine going BANG, don't have the cash for a rebuild want to
get it sorted ASAP.

Thanks, ben.

 

just going back over my e.mails and i saw your one about a rattle its
not pinking is it?water pump noise dos travel,exhaust cover in the
engine bay which covers the manifold.check that out with engine running
and holding it in places to see if the rattle stops.
