I took my Boxster into the shop today to diagnose a "chirping". It really sounds like a belt noise but I took the belt off and the noise remained so off to the shop it went. They spend hours with a scope and found the noise to be coming out of the front center of the engine. I'm not sure if I want to invest a ton in tearing the motor apart but might try a shot in the dark with timing chain tensioners. Do you think that could be it? Any other ideas?
More "chirping" info
The chirp is the loudest at idle and then goes away as the revs climb (as oil pressure increases?). The chirp is sometimes just a single chirp and other times its continuous.
Thanks guys
