* Oil Leak: This is the most immediate and likely problem. Oil will leak out of the hole where the tube was, potentially onto the ground, and possibly onto hot engine components. This will result in an oil loss, leading to engine damage if not addressed quickly.
* Difficulty Restarting (or inability to restart): A significant oil loss could lead to insufficient lubrication, making the engine difficult or impossible to restart. Attempting to start it could cause further damage.
* Engine Damage: The most severe consequence. Running the engine without sufficient oil will cause major damage to bearings and other internal engine components, potentially requiring a costly rebuild or engine replacement.
* Mess: Oil will be spilled, making a mess under the car. Cleaning this up is a necessary but unpleasant task.
What to do if this happens:
1. Immediately stop any attempts to start the car.
2. Locate the oil dipstick tube. Try to carefully reinsert it. If it's damaged, you'll need a replacement.
3. Add oil. Once the tube is secure (or temporarily plugged if it can't be immediately repaired), check the oil level and add oil as needed. Use the correct type and amount specified in your owner's manual.
4. Check for leaks: Carefully inspect the area around the dipstick tube for any leaks.
5. Tow the car to a mechanic or repair shop: Don't drive the car until it's been inspected and the problem has been fixed to avoid further damage. The tube may be loose due to a worn or broken seal, which needs professional attention.
The age of the car makes it more likely that the tube is simply worn and loose, or that the seal around it has failed. Don't attempt to simply push it back in forcefully; you could cause further damage.
