Here's why:
* Misfire and Engine Damage: A spark plug in the engine cylinder can cause severe misfires, leading to damage to the piston, cylinder walls, and even the crankshaft.
* Fire Risk: If the spark plug is in contact with fuel or oil, it can ignite and cause a fire.
* Oil Consumption: The spark plug can create a leak in the engine, leading to oil consumption and potential damage to the oil pump.
Here's what you should do:
1. Stop the Engine Immediately: Do not attempt to start the engine again.
2. Don't Try to Remove It Yourself: This is a very difficult and potentially dangerous procedure.
3. Contact a Mechanic: Immediately take your Durango to a trusted mechanic. They have the tools and expertise to safely remove the spark plug and inspect the engine for damage.
Do NOT drive your Durango with a spark plug inside the engine. It's a significant safety hazard and could lead to serious engine damage.
I hope this helps! Please be safe and let a professional handle this situation.
