Spark Plug Hole Fix
Spark Plug Hole Fix Ok guys, I just got screwed blue on a plug change on my lt1. Some ******* that did the first tune up before I owned the car cross threaded plug #5, and so I cannot thread the new one in. Therefore, I must now tap and helicoil the hole. I'm not sure if the douche did the same thing on the other head, but I'll cross that bridge when I get to it. My question is: is it possible to repair a spark plug hole with the head on the car?
Again, this is the #5 plug on the driver's side head. Thanks.

if there is a way to do it with the head on the car i havent heard about it. The aluminum shavings from taping the hole would go right into the cylinder, i would think anyways...
You could try a thread chaser. You can pick one up at NAPA. There a little pricey but it could save you a lot of time and money.
It basically works like a thread tap but it starts inside the cylinder and works its way out so you dont get metal in the engine. It follows the good threads and cleans up any bad threads. You insert it in the plug hole, expand it in the cylinder and then chase the threads

spark plug thread strip is very common on mustang world lol ( spark plug blow out ), Most use their kit at advance auto part or napa without problem. btw the kit from timesert is one of the best kit I heard of.
Thanks for all the help guys. I ended up pulling the head and putting a timesert in. What an absolute PITA for a simple plug change. I guess I learned my lesson that you CANNOT trust anyone to work on your car except yourself.
