Conversation Between Curless and steve sepaugh

I just repsonded to your post. They were all broken as soon as they came loose. Just turning them with a ratchet you could hear them snap off....it sucked but it was not the worst repair I have had to do!

hello curless,
I agree with your assessment of the impact not being a good idea. Decarbonizing the engine then using the leverage buffer tube to break loose the spark plugs while introducing penetrating oil and carburetor cleaner into the tube around the spark plug works. you just have to work the plug back and forth so the penetrating oil and carburetor have a chance to dissolve any remaining carbon and always use a ratchet and never an impact. Impacts won't even fit into the area on the back cylinders on f150s. My truck had 150,000 miles on it when I removed the original plugs (Pzt2f) with out breaking any of them. aonrachtools.com
