So I was driving along down the road and my car started to sound like a pissed off vtwin, popped the hood and see the spark plug blew right out of the head and the plug itself looks like it blew up, question is has anyone else had this problem? And is there a way to prevent it from happening again?

 

On the '88 listed below your icon or on an S197 (05-14)?

 

I had a friend this happened to on his Dodge Neon. We had to back what was left of the plug out of the head which was seriously like 8" deep and he didnt have a new plug, so he drove to Napa on 3 cylinders. Don't know why it happened and it never happened to him again, so I chalked it up to a faulty plug that somehow made it past QA.

 

On my s197, haven't been the site in awhile currently have a 2007 GT and wcgman the plug didn't just back out a little bit the whole thing shot out of the cylinder

 

I'm interested in this thread, really wild!

 

Ill will upload pics of the plug when I get a chance, the whole tip blew up

 

Here it is

 

looks like it was only in by the first 2 threads, any threads left in the hole?

 

Well it damaged the threads, the dealer had to heli coil the head, only reason I took the car to them is because the car is under warranty but turns out that spark plug related issues are not covered under warranty so I had to pay out of pocket for the repair which I could have done myself but wanted to make sure no pieces of the plug went down into the cylinder.

 

I've also herd that on the 4.6 motors if you over tighten the spark plugs that they are likely to shoot out? don't know how much truth is in that fact i'm still currently pretty new to the 4.6 motors
