HELP! Broken bolt for coil pack!
So I was changing out my spark plugs this morning, and ran into a slight issue with the coil pack and plug that is second from the firewall on the passenger side. I was taking out the bolt for the coil pack, and it snapped off. Thankfully I was still able to pull off the coil pack and replace the plug, but I was not able to get bolt the coil pack back down. I plugged it back in the pushed it in all the way, and put some dielectric grease on it. It is staying in place and is moving around at all. The bolt broke flush, so there is nothing for me to grab so that I can try and turn it out. What do y’all think I should do about it?

Also, what do y’all think about the old plugs? Should anything about the way they look concern me regarding my engine? All the gaps were as expected for not having been changed in I don’t know how long. Thanks!

Not sure what to say about the plugs, but one of my coil pack bolts has been broken since a month or so after buying my '13 in Jan. of '17. Haven't touched it in over 20k miles of very aggressive, tuned driving, regularly seeing 7k shifts. I've had 0 problems, it hasn't move at all. Used dealer I bought it from didn't want to drill it out and or remove head while I was still under powertrain warranty, and I forgot that it was even broken. I'd feel confident if none of my coil packs had the retainer bolts on them. Those coil packs are in there tight to begin with lol

Youll have to drill and use easy outs, now be honest did it actually break coming out or did you cross thread it putting it in lol
Try using one of those kits with left hand drill bits and make sure you plug any holes nearby if you dont have compressed air to blow out the shrapnel

A buddy of mine had a similar circumstance on a 2005 4.6. I tried the left hand drill bit trick an no dice it may work in your case I've had great luck with it in the past. So what ended up working was soaking in a good penetrating oil and usin a vibro stick, Metal engraver what ever you wanna call it its like a pen with a hose to connect to air it vibrates and we just kept working it and they came out with the aid of the vibration. My dad was a block line employee at GM on the 5.7, 5.3, 6.0, 4.8 at romulus powertrain and he taught me that trick works great. heres a link to the tool im referring to. good luck dude
