 :(
 Anyone  know what can be done about a fix to this dilemma.

The plug felt tight so i  gave it some WD40 took my time removing it.  I had put copper anti seize on the plug when i installed it like i do each time i change the plugs. Don't know why this time it ripped the threads.

Anyway,  can this be fixed.  Im starting to pull the head now.

Joel:
I use Time-Serts, a solid thread insert,    I put grease on the thread cutter to collect the majority of the aluminum as it c8ts the oversized hole, never had a return do to the insert coming back out.
The option with the head removed is similar but more like a rivet style that is pressed into the head.

Cheers  Joel,
What size drill bit do you use before you use the thread tap?

Finster101:
The steel inserts should be available as a kit that will have the proper reamer instead of a drill bit.  It will also have the correct tap and an install tool.  I have done many Northstar engine blocks with this method.

Joel:
Correct just google [ time-sert thread repair kit ]  and it will bring up options. I thought I posted a picture of the kit but obviously I didn't.
