Hey guys, I know this topic is beat to hell, but what options do i have for fixing this problem...I know i could heli-coil or time-sert it, but Just how reliable are these fixes? and how much would replacing the head cost me, and is it even worth it. btw it's a 1999 Cobra.

My other question is which cylinder is #5 in our motors? because im throwing a P0305 but the cylinder that blew the plug is the drivers side closest to the radiator...I dont know if this is #5

ANY help would be great because this is my DD so being down for a long time really isn't an option :/

99' Cobra, 64k miles

If this pic is right (google images) the #5 is the same one you blew the plug.



EDIT: This was listed as a 99 GT firing order but I would think they are the same for the Cobra.

You said you blew the plug, the pics look like there is thread there. How did you break the end of the plug like that?

The treads on the Head is stripped, and when i took out the coil pack the plug was just sitting in the hole like that, and the piston definitely hit the plug at some point cause the tops all crushed down, But yea, no clue how the plug ended up that messed up

How reliable are heli-coil's or time-sert fixes?

I had the same problem and I used the guys over at
Blown out spark plug . com, there web sit is very informative and I recomend them.

helicoils are the cheap way out that i have hears are not the way to go. Time serts are a better rout. I don't know what goes into doing either one as I have not read up on it but everytime this topic comes up helicoils get thrown out the window right away.
