I gotta new valve cover for my moms 2005 Nissan Altima 2.5l. I put the new cover on and when I got to the spark plugs I started bolting them down. But the little copper or gold looking part started to pull out as I was bolting down the spark plug wire. I couldn't get them back in. I tapped on them then I tried to push them in but nothing. Please help i dont want to put the old one back on. I had bought the valve cover off eBay can't get to the seller tho. This pic is of the old cover. But took it so i can be clear about my situation incase i wasnt.
