    Hello everyone,

    My 2005 stang had an misfire today and I went to check the sparkplugs. I've come to realize that 1 of the coils wasn't holding on tight because of the bolt was loose. Did a further check up and it seems that it does screw into a plastic hole that broke. Did a search online but couldn't find the part number of this. My question is if anyone know the part number of this cover or any other idea how I can fix this.. I did put a tie wrap on it for a temporary fix.

    Thank you in advance for any suggestion.

    Holy s**t!... That's aluminum, not plastic.... and it's a part of the valve cover, not a part you can replace.

    You'd have to buy a new valve cover to fix it. Tasca Parts has them for about $120 each. Here's the part numbers:

    Driver's side: 9L1Z-6582-C
    Psgr side: 9L1Z-6582-D

    It looks like it was smashed downward or pried outward.... Or maybe a much larger bolt was forced in there... But I have a hard time believing that just "happened" over the course of normal operation.

    Maybe try some JB Weld and fix it up. There really shouldn't be that much stress on that part just holding the coilpack. I agree with Mxx448 - that didn't just happen.

    And on a side note, clean up that engine bay, your motor will be happier.

    My first thought was Holy Carp what else is broken or falling off!

    Or, you could go full ROADKILL and use a zip tie.

    Holy Carp - sounds like a fishy story!

    Kinda looks like it might have been in a river or flood.
