Being one of those DIY'ers, I decided to tackle the spark plugs on for 05 F150 - 5.4L. Ive completed 4 of the plugs and of course they all broke. The question I have, is while pushing the ceramic piece into the broken metal portion of the plug (so I could tap it and pull it out), the ceramic pushed through the terminal cover (the part that covers the electrode). The ceramic didn't break but the metal portion did and I think (don't know for sure) that a small piece went into the engine. I would guess at biggest it would be about 1mm thick and 1-2mm in length and width. I couldn't tell for sure because the ceramic pushing through stretched the metal and broke it. Will this ruin my engine and is there anything I can do to get it out. I plan to get a magnetic arm to stick in there and see if I can find it that way. Would a simple oil change remove it? I don't know much about the inner workings of an engine, where the oil comes in and goes out, etc to know if this would get washed through and then stuck in the filter or if I'd be able to flush it by running the truck for 5 minutes and doing an oil change. Any thoughts would be great. I don't want my attempt to save 500 bucks turn into costing me 3000 for a new engine.
