I was able to remove all 8 plugs...no problem. The passengers side front plug seemed "loose" as I removed it. The threads were not as snug fitting as the other seven. When I put the plug back in that hole, and snugged it down, I didn't feel that positive seating of the other seven plugs. I just felt "mushy"....I didn't take it back out ( fingers crossed )....I'm waiting for it to work loose and POP...blow a hole through my hood!
