So I was driving down the road one day and the car was kinda sputtering at sometimes but had to make it home, so I made it home and then the next day it didnt start. That was like a month ago and I now looked into it more. So its the 1.0 3 cyln with 130,000 and I pulled the plugs and the 2 outside plugs were smashed by the pistions. The middle one was fine, What could this be? Broken timming belt? Crank walk? Or? I love this car so any help would be great!! P.s What is the correct spark plugs for this car? Ill double check I that i have the right plugs

i'm pretty sure any plug that has the thread that fits your geo is the right one. if your plugs are all smashed up you probably had debris inside the combustion chamber that the piston was smashing up against the plug. |

Yea I'd take the plugs out and try to start it. It will shoot all the crap out of the combustion chamber...or at least some. |

If the proper spark plugs are installed, this is the understatement of the century. Shine a flashlight down in the spark plug holes and rotate the crankshaft so you can see the top of the piston. You might have quite a bit of carbon on top of your pistons. A 17mm socket on the crankshaft bolt will rotate the crankshaft. Let us know what you see.

Something is horribly wrong and that engine needs to come apart to see what was wrong. There's no putting spark plugs in and hoping for the best, you're way past that point. |

The shape of the combustion chamber and the way the spark plugs are positioned make it so that even if the piston somehow detached from the rod and flew up it would hit the head and never reach the spark plug. Pics of plugs please? |

If there's some ferro-metallic debris inside, maybe you can use one of those telescopic magnets to fish it out via the spark plug hole. Don't know if it would be able to pull up a loose piston to see if it's disconnected. If there is excessive carbon, maybe you can get a short length of cable and cut off a few inches of insulation and attach one end to a drill and route it somewhat clean and use a vaccuum hose to suck the carbon fragments out - just looking for ways to avoid dissassembly of the engine. |
