[QUOTE="mustangc, post: 9212926, member: 87570"] I broke 7 out of 8 spark plugs during removal. They broke in the wost possible way, too: leaving the ground strap and part of the ceramic still inside the cylinder head. I followed Ford's TSB to the letter, but it doesn't work. The TSB specifically says to remove the plugs on a cold engine to minimize the chance of thread damage, but I would think it would have been better to remove the plugs from a warm engine. The aluminum in the head expands faster than the stainless or ceramic in the plug, therefore loosening its grip on the plug. Some heat might have also softened the carbon deposits a little. I think Ford's TSB gave me some bad advice. Now I have the extraction tool to remove what's left of the plugs. It uses Locktite to bond a pin to the inside of the ceramic, but there are two problems: 1) The tool only comes with 4 pins! They cannot be reused. I need at least seven, and I would have thought the kit would have come with 8, considering all of these three valve engines are V8's. DUH!!!:idea: 2) The Loctite won't bond properly if the temperature is not at least 70 degrees. It is SNOWING outside and the temperature is in the 'teens!!! I have a heater in my garage, but my garage, like most, isn't insulated very well. Achieving and retaining 70+ degrees for 8+ hours in the beginning of January will be nearly impossible. So NOW what do I do?:shrug: [/QUOTE]
