Hey, when I got my 300 I was talking to a friend of mine as we were looking over the car on the first day, and I said I needed to find out how to remove the cover. In my previous Dyno business most covers were held down with bolts and tricky hidden covers. (OK, not so tricky!)
My friend, who owns the best import car repair shop in downstate Illinois (I am biased, but they are pretty good) just grabbed the thing an pulled up and it came off! Since then I have taken it off at every car event so people can actdually see the engine.
I still think these things are silly. Who in their right mind is going to care to look at these cars in the future at car shows.... "Man, that is a darn fine looking piece of plastic you have there in the engine compartment!' The SRT-8 did it better, but they still need to show the actual valve covers and take the time to make them look good.
Let's start a "get rid of the plastic" movement!
no offense to those that have done a nice job of painting or tricking out their covers, they look great, I am just an "engine" guy and would rather see the real thing.
