Ben, you are going to have to bite the bullet and pull the head if you don't want to end up with bigger problems. If it was me I would not try to retap it because most likely there is not enough metal left to rethread. Go get a heli coil, if you follow the instructions the heli coil will be strong then your original threads.

btw for the future always put a little Never seize on the threads of the Spark plugs, because think about it. steel spark plug and alum head. this will save this from happening agian, and no it doesnt hurt anything..

 

thats what i do.

 

Yeah I do that every time I change them, however these are the original plugs from the factory.

 

I picked up a thread chaser yesterday the guy at salvo's said the biggest ones they had were 14mm. I looked at it and it looks like the right diameter but now that i have it home I compared it to the plug i don't think it is the right thread spacing.

This sucks I think I might just take it somewhere and have them fix it.

 

ya i kinda figured just giving a tip didnt know if you knew tis all
