There is one thing my old 123 can use - sound dampening.

I removed all of the sound deadener from under my hood when I bought my car because it was all oily and crappy. The noise does not bother me, but now that I work at a GM dealership, I had the embarassing experience of pulling into the lot next to a GMC 1500 Duramax that was idling. My diesel clatter drowned out the Duramax. Then, to add insult to injury, a Dodge Ram that we had taken in on trade on the Duramax drove in and parked beside the both of us. My car's clatter drowned out even the notoriously noisy Cummins.

Oh, the humiliation...

The sound deadening pad through a MB dealership is scary expensive. Is there some other pad or insulation that I can put up under the hood that will absorb some of the clatter? How would I attach it? (I threw away all the crud encrusted clips that held the original old tarry worn out insulation padding)
Any ideas?

Regards to all.
