Default a victim of spark plug blowout

so today i was on the freeway, just cruisin and all of sudden i lost a little bit of power and my engine sounded like i was using a semi truck "jake Brake" and this wasnt gradual, it came on instantly. so i pulled over and popped my hood (in nuts rush hour traffic with a shoulder that my stang barely fit into lol) and so im listening with my hood up and it sounds like the passenger side cylinder bank. the noise was completely rpm dependant and sounded like compressed air escaping through a small hole. i couldnt really take a good look though (due to traffic and pouring down rain) thankfully AAA came to my rescue and got me home. this sounds like plug blowout to me. any other opinions? also i have searched this forum and found that some people used helicoil to fix this. so i wanna try that (if it really is plug blowout). please tell me i dont have to pull my crappy romeo head off to fix this. and thanks for any help

Huh???? I think he would have know if he threw a rod through the block.


If your plug blew out, you would know it.

Just look under the hood and see if you have a coil pack scattered in 100 pieces.

Doesn't take a lot of investigation.

wtf, does the coil?pack have to do anything with it....
your @+*!'in retarded!!!
Could a moderator please ban this person.

The coil pack, my friend, connects to the spark plug on the SOHC 4.6 engines.

When the plug blows out, the coil pack usually ends up exploding due to the force of the plug coming out with such violent force.

Now, who's retarded.

alright so today i pulled my plug out. passenger side 3rd cylinder from the front. im not sure what the cylinder number is. 5 or 6? but my cop boot was torn in half and my spark plug had no gap. i talked to my dad (a bitchin mechanic but he lives 100 miles away so he cant help me out too much lol) and he said if the piston contacted the spark plug that the whole bottom of the spark plug and the electrode would be crushed, which its not. i can see on the threads of the plug, it looks like the plug was physically pulled out of the head, but i believe that since the threads from the head are not on the plug...that my head still has threads in it. *im praying to the stang gods* so whoever changed my plugs before i put the car in used autolite 764's. so my plan is to buy another cop. where should i buy just one? it is to my knowledge that they are all the same, just with different stickers on them. also im gonna buy motorcraft sp493 plugs. if it blows out again then i am probably gonna do a timesert. im gonna try and post pics but dont know how. opinions?

Let us know what you find, I'd be interested to know what caused this.

I'm a recent GM convert, and I can't say I dislike my mustang, I just don't get how Ford screwed up so much when it comes to the engine. Spark plugs blowing out is absolutely ridiculous. Plus the fact they were pushing 265 horsepower when their competitor was making well over 300...

My GT had the original plugs with 60k miles. I've had the car about a month and already blew out a plug. I went ahead and replaced them with new plugs, and found that another was loose. I torqued them all to spec and have my fingers crossed.....

Oh well, I'm sure I'll warm up more to it if I go for a little while without parts flying off of the car
