Coil Screw Broken :(

[jordanwince]

Hey guys.

So I registered here because I have a buddy who went to a shop and was told it would be 350 bucks to change one coil pack. So, me being a hands on, DIY mechanic, I know my fair share of motor work, so I told him Id do it for free. I go there, unscrew the bolt holding the coil in place, pull out old, put in new, and started to screw the bolt back it and be on my merry way...thats where it got ugly...

Now that the head is broke off, as you all know, there is no way I could grab the stud with vice grips from the side, therefore, had to try from the top. Finally got it going with the little room I had to turn with and it broke even more. Now its broken down so it sits flush with the valve cover.

So now I have 2 questions....

1. If I was to take off the valve cover (which I feel would free up the remainder of the stud and I could grab from the side), how much would that expose the stud?

2. How important are thos bolts? Dont get me wrong I dont want to go that route, but I have electrical tape on it now and it runs fine, but if I was to not fix the stud, would the coil pack move around alot or will it sit in place pretty well with the harness attached?

Please helpppp!

What year?
V8 or V6?
The answers make a difference.

AFAIK, the bolt hole is not exposed on the other side of the valve cover (if it were, it would leak oil if you didn't put thread sealant on it), so taking the valve cover off won't help at all.

If it's a V8, then putting some high-temp foam between the COP and the top of the COP cover should hold it in place.

BTW, they are COPs (Coil On Plug), not coil packs. There's a big difference.

I agree with Joe. That screw is likely to be a bitch to remove. If you can find a reverse rotation drill of the correct size, you might back it out or at least prepare for an attempt with an easy-out. Or you might drill it oversize and tap for the next larger size screw. Or replace the cam cover. Or just let it be. It's not very likely to go anywhere.

you need a reverse drill bit to get it to spin out or a regular drill bit to basically eat the screw away. I recommend a tap and die set also because you could ruin the threads.

It is a V6. So the best bet and easiest way really is to get another valve cover? It was a bisch to turn (granted the space I had was limited as yall know), so I am worried it is cross threaded.

the tap and die set will re thread it so the cross threads do not matter
