Possible Causes:
* Damaged injector: A cracked or worn injector nozzle can allow fuel to leak past the seal and into the cylinder head.
* Loose or damaged injector seal: The injector seal is designed to prevent fuel leakage. If it's loose or damaged, fuel can escape.
* Damaged cylinder head gasket: A blown or damaged cylinder head gasket can allow coolant or fuel to leak into the cylinder head, potentially causing the fuel leak you're seeing.
* Damaged cylinder head: A cracked or warped cylinder head can cause fuel leaks. This could be due to overheating, or even damage from a blown head gasket.
* Incorrectly tightened cylinder head plug: If the plug is not properly tightened, it can leak.
* Damaged cylinder head plug: The plug itself may be damaged, allowing fuel to leak.
Important Notes:
* Safety first: A leaking fuel system is dangerous and could lead to a fire. Park your car in a well-ventilated area and do not attempt to start the engine.
* Professional Diagnosis: It is crucial to have a qualified mechanic diagnose the issue properly. They will be able to identify the root cause and repair the problem safely.
* Don't delay: Driving with a leaking fuel system can cause further damage and is very unsafe.
Additional Tips:
* Check your engine oil: If you have a damaged head gasket, you might find fuel in your engine oil.
* Look for other signs: Check for other signs of problems, such as white smoke from the exhaust, overheating, or a loss of engine power.
