A week ago my 99 Camaro SS started making a squeaking/chirping and a tapping noise on the drivers side of the engine. It was only driven 3 miles after hearing it start and has been parked since. It has a mild custom comp grind cam, but no other major upgrades other than pacesetter headers.
I have posted a clip of my car below. Any thoughts?

Thanks in advance,
Brad

 

Ever figure this out?
