engine chirp

my engine makes a chirp sound at idle and gets faster if i rev the car. i searched about it and found things suggesting its the plugs not torqued down enough or something about a crank case seal. i also read to pull the dipstick and it stops, but in my case it seemed to get louder. any ideas? thanks guys.

A/C on?

A GM Tech said that he'd recently been having a rash of these cars (1.4) with bad serpentine belt tensioners. Sure enough, I've heard mine chirping twice now with the A/C on.
