so i own a 2.3L duratec 2005. it has a plastic valve cover on it right now. i bought a metal valve cover for it off a 03-04 focus that came with the metal cover. i noticed that mine has 5 holes, then one i got has 4. im pretty sure the hole between cylinder 2 and 3 is the coolant sensor?!?!? is there ways around this or does the valve cover i got just not work with it?!?!?! anyone have this problem before! i tryed looking EVERYWHERE on the internet and i cant find any info!!
