Seepage at the cylinder head gasket can range from minor to severe, and it is always best to have it inspected by a professional mechanic to determine the extent of the issue. Minor seepage may not require immediate attention, but it should be monitored regularly to ensure that it does not worsen. If the seepage becomes more severe, or if it starts to cause problems with the engine's performance, it will need to be repaired.
Some signs of cylinder head gasket seepage include:
* A small amount of coolant leaking from the engine
* A white or gray smoke coming from the exhaust pipe
* A rough idle
* Engine overheating
* Loss of engine power
If you are experiencing any of these symptoms, it is important to have your vehicle inspected by a mechanic as soon as possible.
