wow..I havent posted here in a long time..but..hope I can find help

Last week...the sparkplug on the driver side of the engine...second from front...shot out...tore up my COP...and stripped the threads on the inside of the cylinder head

Ive been researching on it...and it seems common in our crappy aluminum heads and in ford trucks...and people are repairing them with timeserts http://timesert.com/

anyone can help me out...or point me to a shop that is pretty good at installing timeserts or helicoils in our aluminum heads??

I really dont wanna dish out money for a head replacement..that can spit a plug out again

I wouldnt mind buying the kit myself and doing it..but just really wondering if anyone had experience with them

thanks

alex

That sucks Alex. How ya been? Haven't heard from you in a while.
That is definitely a common issue. Did you recently change your plugs?

sup peej...ever since I moved to tyngsboro from lowell...ive just been wicked bz with work and school and junk..never really had time to post and stuff...

but im doin good..except for this problem with the stripped threads

yeah..I changed my plugs like 3 months ago....

today...I was checking the torque on the other 7 plugs..and all are fine

I just really wanna get this fix...it sux driving my sisters red 01 honda prelude around...I hate being seen in a freagin rice car...especially when she has one of those folger can muffler

Which plugs did you replace them with? I guess the new Ford SP-493's have more threads and are supposed to help with the problem. Aftermarket plugs have been known to "spit" more often than OEM plugs.

They also say don't use anti-sieze as it will cause them to back out.

I know that doesn't help now, but the 99+'s are very prone to throwing plugs....reason why i haven't touched mine yet.

i wish i knew...but I dont think it matters on the plugs threads...since they are goin into the same head wich only has a few threads to hold it anyways..crappy ford design

my stang is at 140,000miles and i've never touch antiseize..why lubricate something that can come loose anyways..just torque it to spec and call it a day. Also, a lot of sparkplugs are designed to prevent seizing up anyways

ive changed my sparkplugs once at 100K...put in autolites 764s...they crapped out @ 135K miles (since they only have a life of 30k)....and I put in autolites again...and that cylinder head just decided to spit 1 out

but..anyone know anyone or a shop that can help me out?..i wanna drive my stang again before next week comes..i really need my car back for transportation to school and work

thanks

There was talk on Stangnet about a great DIY kit for this sort of thing which guys have used with good results. It was a while back so i'll see if i can find it

i know the cheap kit is helicoils (but with this..u dont really know how far the helicoil actually sits in the hole...so ur sparkplug might be too low and hit the head..or too high)

and the more expensive kit are timeserts (works awesome...and sits the sparkplug similiar to OEM and is a permanant repair)

thats the only 2 kit I know

I was gonna buy the timesert but I just wanted to see if a mechanic had one already and can do the job for me

EDIT: just called a local mechanic thats owns a S281...he quoted me 300bux for a lock-n-stitch for insert kit..another place in tewksbury charged $300 using the helicoil kit..

wonder if I could find a better price for the rethread at other shops
