Default Cold Start Up Noise

My car has developed the sound a baby chick or a chirping bird on a cold start up. My car is not a DD so i do not drive it all that much. What can this noise be? At about 1 minute into the vid you can hear the chirping sound.. Any ideas?

I was thinking a lifter is leaking down? But i have no ideas

Is your oil pressure steady?

I didn't hear it in the vid, but try the drive belts. Spray a little wd-40 on them when the are making the noise. If it goes aways there you go. Lapping compound works great to get rid of it for good. Just a little dab.

Heard it. Try the belts. Spray them while it's running and making the noise. If it goes away thats your problem. I had a similar noise (a little more severe) and that was it. The lapping compound got rid of it for good. Easy to check. If that doesn't take car of it you can remove the drive belts and fire it up, see if it goes away. That way you eliminate all the accessories.
