I'm having the same problem. There was a terrible noise from the engine. Took it to Pep Boys nearby
where the mechanic diagnosed it as being a bad bearing on the timing belt tensioner. He said there were clearly visible metal filings around the bearing.
He said there was no damage to the engine because the timing belt was intact. I Got Saturn Corp. Customer service involved and they gave me a case#(I had to have it towed to a Saturn dealer to be officially diagnosed). Here's the deal: manufacturers of these timing components(eg:Dayco, Gates)recommend that when you change the timing belt you should also replace the tensioner and then they'll warranty the parts for 60,000mi. That's why they sell them in a kit. However, they don't make a kit for my model saturn only the timing belt. Saturn won't replace the timing tensioner with the timing belt(eg:if the water pump leaks on the timing belt) under warranty unless it's bad. Here's the kicker:for the vehicle there are 2 kits. VIN#YY6. The kit #22708845 will not work only kit #24449772 due to a break in the VIN #'s according to a service manager at a local Saturn dealer. Most Saturn parts dept. I contacted were'nt aware of this and could'nt find the latter part#. :D If anyone would like to send me a starbucks or similar gift card for this info.
Addendum 04/10/2007:now the the service manager is'nt sure which of the saturn part kit(s) is for my car : :x :shock: :o :(
