did the whole spark plug pop out threads and all or are the threads of some of the spark plug still in the cylinder head-What year is your Car?-What make and model is your Car?-How many miles are on your Car?-What type of engine is in your Car?-What have you already tried?
the whole sparkplug came out of the head , on the end of the plug there was a treaded incert that the plug was treaded into much larger than the plug . 2002 ford f-250 engine 5.4 v8 143,000 miles . looks like someone tried to tap the whole bigger an retread
yes someone put in a heli coil or threadcert as that is a repair for a spark plug threaded hole in a cylinder head
at this point you need to take down that spark plug with the incert on it to your local parts store and pick up a heli coil or threadcert kit
the kit comes with great directions to install them
now I am hoping the thread repair they used did NOT mess up the cylinder head as if that complete threadcert came out with the sparkplug there is a chance installing a new thread repair may NOT hold the plug in to spec and might blow back out on you
but at this point you have to attempt the thread kit and if the plug blows out again the cylinder head will have to be removed and repaired at a machine shop im sorry to say
now I am hoping they used a heli coil and if they did put a threadcert in that will more than likey hold good for you
if they used a threadcert already its going to be try a new one and if it pops out the head will have to come off
here are the picture of each the threadcert is a round threaded repair and a helicoil is basically just replacing the threads as you can see from each picture
what does it normally cost to have the head reworked an put back together .
you are looking at 15 to 21 hours labor depending if your going to send out both heads which would be wise to do
as for just the machine shop price to fix the plug hold @ $ 50 to $ 100 to fix the plug hole
is there a dependable shop in my area am in madison al. 35758
