Baseball card in bike spokes sound

[sandman0023]

Finally took the car out for the first time last week. Sounds fine at idle however, when I give it gas it has a baseball card in spokes sound. It only occurs when on the gas. It sounds like its coming from under the hood. The first area I checked was around the fan and that was clear. Any suggestions??

I had a sound like this in my 01 GT. Does it make this sound only when under acceleration or all the time....the culprit was a spun rod bearing in my car....I'm sure if it is not this, someone might be able to figure out the problem....

Exhaust leak. You can get a ticking like this if the headers aren't bolted on all the way or where the headers bolt to the H or X pipe.

It makes the sound only while accelerating. I'll check to see if the headers & x-pipe are tight.
If it is the rod bearing its pretty much toast then, right?

If it's only under acceleration than I would second the exhaust leak idea. Sounds like your headers may have a leak. When I changed my headers on my old exhaust the bolts kept backing off and I blew a couple gaskets that way, made a sort of ticking noise.

I third the exhaust leak. get some stage 8 locking bolts and be done.

def. exhaust leak. i had that problem with my 94 cobra after i put on my bbk headers. blew out at least 3-4 gaskets.

A few months back I had a weird noise like that in my 91, ended up getting worse over time and being a cracked flexplate. When it first started it was fine at idle and would only make the sound during acceleration. Then it became loud and constant.
