K, odd, my engine looks the same as that......and that silver section comes off with the black plastic cover??? Mind you, mine is an 02, maybe 03's were made different, I dunno. I took my cover off, painted it and put it back on without having that silver section removed.
There are two different designs for the engine cover out there. If you have extra holes in the valve cover where the 01&02 smaller cover would bolt on you could just find one and slapp it on. Otherwise you'd be looking at a new valve cover and at that point it just wouldn't be worth it.
