noise coming from engine/need help

[1990silverbullet]

So it started this morning... I don't know what it is and im afraid to drive her.
this is the first time making the noise. Could it be a bad bearing under the timing cover or something??After its warm it doesn't make the noise anymore. I couldn't figure out how to upload a video so I put it on youtube (https://youtu.be/J1-_DXB9CKA) I only got a couple second clip of the noise so im not sure if anyone will be able to help but anything would be great.

It..doesn't sound like a constant noise. Almost like a belt or something. I think with a bad bearing it would be pretty constant with RPMs. Did you lightly rev it?

at first I thought it was exploding but after a little I started it again and it started but didn't seem to idle down or anything so I reved it lightly till it was warm and it stopped. It only happens when its cold. Im pretty sure its my timing belt. Everything on my runner is stock. So anything I do to it is its first time its having it done. Do you thing a bad bearing under the timing cover could be the culprit?

This morning I was lucky and it didn't make such a terrible noise it just sounded like a blown bearing. Just don't know which one

If you rev it up does it get worse or go away......

it gets worse, till its warm then it gets quieter.

Mine had a spun bearing, at idle it was very quit, as it was revved up it sounded like crap and got to knocking. It could be a cam pulley, is it only on one side or both.
