On 98 Buick Regal supercharged 3800, what is the purpose of the plastic shroud (with foam insulation) over the top of the engine? Is it for more uniform expansion of engine....would this minimize the intake manifold gasket problem? What are other possible theories? What effect if it is removed?

It does two things. One- Noise reduction. Two- Cosmetics
It makes it look nicer. You can take it off, or leave it on. Makes no difference. I leave mine on, becuase, like I said, it makes it look nicer.

It is there to keep you from seeing the engine. No one likes seeing engines.
