Guys and Gals:
As I type, the GP is in the shade of the garage with a coat of wax drying on it.

After a good washing, I removed the plastic engine cover whilst detailing the engine compartment. My question here is do more of you leave the cover on, or remove it and allow the purty S/C to be visible when the hood it up. I would also think that the cover traps engine heat in/around the top of the motor to an extent which cannot be a positive thing for longevity.

Are there any reasons to NOT leave it off?

Your input and opinions please....................Don
