Hi Everyone,
I was warming up my 986 for an oil change this morning, and when I exited the car I noticed a new sound coming from the engine. It is not audible from inside with the windows up, but once you are outside it almost sounds like a diesel. My '99 has 101k miles, I am thinking it could be the idler pulleys, which are some of the only components I have not changed. I installed a new water pump & belt at 95k, and the RPM's at idle are normal. I think this sound is constant, but it is difficult to hear while driving. Any suggestions/thoughts?
