Just had some issues today

Ok so after work I got in my car to start it and I hear a pop and my engine is chattering really bad. I pop the hood and one of the coils is lose. I take the coil off and thankfully the spark plug didn't come out too. I tried to tighten it back up but it appears the bolt is striped. Do you guys think I can just get a new bolt to tighten it back up or do you think the coil is shot too?

check and make sure the spark plug is still tight in the head. they can be loose and blow a coil out. if the plug is loose it probably tore the coil up. and you could just try rethreading the coil bolt to a little bigger size

Re: Just had some issues today

I checked the plug and it felt tight. I've heard of this happening before but the plug usually blows out.

Yeah. Your lucky it didn't. I would figure something is wrong with the coil if it blew out like that.

I'd replace the Coil pack and the plug- if it hasn't been done within the past 40K miles. My Moms Aviator has the same problem everytime a dang coil goes. Now it's just seccond nature. The last time we replaced the coil and the plug no issues thus far. (Knock on wood)

Re: Just had some issues today

Well started working on the car and found some more bad news. When I started the car the engine still sounded like crap and discovered that a a plug blew on the other side and the coil was blown into pieces and the threads for the plug were striped. Me and my dad tried to fix it, but we couldn't find a tap that was long enough to repair it. The local Ford dealer said they would fix it for $200, which didn't sound too bad to me. I figure when I get the chance I'll find 2008 or newer car without those spark plugs that break easy.

Wow 200 is cheap! The dealer I work at charges 800 to helicoil and 4 grand to replace the head. Hope your helicoil holds. those heads are terrible about blowing plugs!

Re: Just had some issues today

They quoted me $200 for labor and since I already got a new plug and coil they are just going to use those. Yeah I was surprised I figured it was going to be $500 atleast.

Re: Just had some issues today

This is a common problem and is probably the biggest weakness on 4.6/5.4 engines. I know of many people who have had this problem, on many different configurations, from bone stock 2v to blown Lightnings... Remember when NABG blew the plug on his truck? Even my car has notorious two piece plugs...

I fix at least one ford per week with the notorious spark plug issue. I just 75 dollars at my shop for labor and spark plug. Most the time i can reuse the coil by using a spacer under the fuel rail as a hold down. If not i get them a new coil which usualy runs around 50-70. I had to make a tool for the tap. Basically its the tap kit you can buy from auto parts store with a three inch bolt welded to it

Re: Just had some issues today

The tap I got would've worked if it was longer. You can turn the tap with a socket, can't remember what size, but the socket wouldn't fit down into the head. I hear Ford is working on lasers to replace spark plugs and maybe that wouldn't be such a bad thing.

Re: Just had some issues today

Just picked up my car at the dealer and everything seems to be running fine. Now just cross my fingers that another one doesn't blow.

Good to hear. From experience with the Lincoln they usually wait about 6-8months What would you do if you didn't have that to mess with?

My Mom is a real good judge of when one is ready to go. She just calls me and says, it is going to happen soon. The last time I doubted her judgement she was correct. It was about 200 miles later. What we did was replace the plugs at 65K with the coil pack. Thus far no issues. Just imagine the old style: Distributor, D-cap, Plug Wires and Plugs.
