Ok, I had a miss in my engine 5.4 Triton Supercrew F150. Its was the 3rd cyclinder, well I had the plugs replaced with Autolite double platnuim plugs, during the replacement I found that I had a leak on the valve cover letting oil onto the coils which destroyed 3 coils, and then found that the number 2 cyclinder injector wasnt working. How many other people have had these problems? What did you replace all the parts with stock? or aftermarket? (what brand)

 

cracked valve cover? id say factory replacement with aftermarket gaskets. cant remember the recomended brand that most everyone on here prefers. cant quote you a price.
