Yesterday I finnaly replaced the cover to stop oil leak. Fan had to be removed. If you remove fan shroud it will make replacement more comfortable. Check out my video to see where the cover is and for cover part number. http://www.youtube.com/watch?v=yFr-wrMli6E
Don't forget to buy cover gasket. Parts were around $10 at the dealer.

Good luck
