I would think that the threads were stripped. Aluminum heads can be problems if the plugs are not replaced on a stone cold engine.

They are expensive but do not require cylinder head removal with careful installation. Several other companies offer similar products. Do a Google or check with your local auto parts house.

Good luck and let us know. :)

Suggested Repair

The spark plug threads in the aluminum head are likely stripped, which can happen if plugs are installed or removed when the engine is not stone cold. Have a spark plug thread repair insert installed carefully without removing the cylinder head, and check local auto parts stores for suitable kits.
