I checked again today and it only does is when the engine is cold. It doesn't do it when it is warm, so I would surmise that it is not the timing belt, correct?
I hope I'm right

Also it doesn't do it for very long, like 1 second of the noise right after the car starts and then all is normal. I'm planning on just ignoring it, unless someone thinks it's important. Anyone think I should do something about it?
Thanks
