03 CTS a little slow to start, sounds sorta like valve tapping but sound not that "sharp", only slight loss of power, stethoscope reveals sound on pass side front of cam up high behind timing belt cover (haven't pulled cover yet). Timing belt replaced 10K ago, 136K on car. Anybody have ideas? Thanks

I have an 03 as well and it also sounds like a diesel. But mine has always sounded like that
