Well not the news i was hoping to hear but WWWPerfA_ZN0W thanks for confirming it is indeed a plastic cover and nice engine pics.
DRbillZ, i maybe wrong but i think gas tank does not go through the same heat cycle as the engine valve cover. My concern is that after a while the plastic cover start to deteriorate and develop leaks later. If 5 or 6 more years down the road no one has any plastic valve cover crack on their 2011 edge, then cheers I worried too much.
