Engine noise

Engine noise
Since late last fall before stoage, everytime I had a cold start, the was a noise for about 1-3 seconds in the motor
Then, it always stopped
It is like a steady "clunk, clunk clunk clunk clunk" very loud and a bit of a hollow sound to it I guess you could say
I havent had her going today, but I will take my camera out today and if it does it again, take a video of it so you can hear first hand!
Yesterday while at a buddies house, we were fooling around with the cars in the yard, and when I started it, THE NOISE REMAINED...This went on for about 4-6 starts....It did not go away
After driving it a while it disappeared, and even after idleing once for 7-8 minutes in disappeared! (until the next start up)
He is a mechanic for a GM dealer and he could not place the noise
We even worked the pully adjuster back and forth and it did not help (as it sounds like its coming from the front part of the motor)
Then we took the belt off and started it up, the noise remained...(maybe slightly quieter but it was still there)
Then as I say, the noise after the next start up, and a while of idleing, it completely disappeared...
It sounded internal, but what internal would go away after driving or idleing for 5-10 minutes???
Might it be a pump getting bad???
Harmonic Balancer?
Has anyone else had this problem and what are some opinions?
THANKS!!!
Also, started it a few times after we were screwing around with it, as I had to go into town, it did not do it upon starting etc, anymore that evening...

Its not doing the steady noise fr minutes now like that spell it took a few days ago
But I might be able to get a video of the noise it makes for several seconds after start up as it is probably the same noise
I will try and get it up today
Do you have any opinions on what it might be before hearing it?

I have had a car do this to me before, and when a harmonic balancer goes bad, it creates the weirdest clunking noises
