would removing the heatshield cause any problems within the engine bay?

 

The battery, heater hoses, platic water valve get a lot hotter, maybe even melt. Why do you want to take it out? Some Big $ engineer thought it was a pretty good idea.

Which heatshield are you talking about? The Big black one between the battery and exhaust manifold, or the one on the manifold directly? If it's causing a rattle, the bolts aren't tight, or the shield is broken. Somehow I don't think your rattle is going away after removing it.

 

its the big blackone bw the batter and manifold

 

As long as all the bolts are tight, and the shield isn't contacting anything, It shouldn't be a cause for any noise.

 

The big black one can be bent to stop most rattling. Also, make sure all the bolts are tight. When I put on the header, all the heat shields on the stock header disappeared. I "think" the engine bay temps went up afterwards and during the summer, I found it somewhat alarming. This compelled me (OK, gave me an excuse then) to get a vented CF hood.

 

If you look on the rear side towards the battery you will notice a pin like object near the heatshield.
I would think if anything that it could be the cause to the rattling noise.
On my car I can see scratch marks on my heatshield due to contact. Although I do not hear any kind of rattling sounds due to this, a rubber stopper of some sort might do the trick.

 

A good idea would be to do what sebring said and check for areas of contact. That will lead to the source and find something to bend or dampen it.
