breaking the ceramic part off a spark plug is probably the most common problem with noobs playing with engines. if you dont have the proper tool to get the spark plugs in/out you can warp it in a big way and the first thing to go is the ceramic part. just using a deep socket isnt good enough unless you know how not to f**k it up. but you guys are pro's right?
lol theres no way im a pro but ive neva broken a plug in anyway b4 lol i guess the only way u can break 1 is drop it in there, over tighten it, tighten it with the socket on an angle or use a rattle gun lmao!
