Blew a spark plug.

you can take it to a shop to have the threads repaired, i think we charge about $500 for it. or else you can get a new head. ford has updated spark plugs with more threads on them to help prevent it. this is why you are supposed to check the torque on your spark plugs every now and again.
 
:shock: Who are you?

Some get a helicoil done. You may go that route first. Cheaper too...Timesert seems to be the best way to go.

Seems like a guy here had one done on his Crown Vic for about 150.


Yo, man! Yeah, funny thing is, I had set up an apt Friday to have my sfc's welded in and he just so happens to have the repair kit. Just got her towed over there since I'm at work and they're taking a look. Hopefully I'll get a good deal.
 
What year car? Still under warranty?

I know ford had a TSB about not re-pairing blown plugs. When I blew mine I had a whole new head put on, but since ford changed the plugs they replaced it all for free....but now I got a small oil leak around that head but its too late to bring it back to ford so I just live with it.

Well you can always try to call the dealer and see if they will do anything for you, its worth the call. Has ford ever done work on the plugs, maybe you can blame them for something they did a while back.

I personally would not repair the alluminum head, I would scrap them both and buy some upgraded ones if you got the spare cash. If not, I have read NOT to use the Hellicoils for repairs and to only use a Timesert kit (that comes from SVTech76 on here).

You can get a new replacement head for around $350, adding gaskets you are at around $400.

Then you could have someone do the install or try it yourself, check with your local race shops and see what they say, maybe they have a deal on a set of upgraded new heads.

BTW, plugs being blown out are common on the 4.6's, so maybe if you get a nice person / manager at the dealer they will give you a xmas present and warranty it for you.

Well all in all, 200 bucks for the head repair then another hundred to have my sfc's welded in and they got it done in less than a day. Needless to say after a prognosis of thousands of dollars and a couple weeks out of comission I'm pretty pleased....
