Why is antifreeze in the spark plug hole of a 4.6l ford?

There should not be antifreeze in the spark plug hole of a 4.6L Ford engine or any engine for that matter. Antifreeze is a coolant used in the engine's cooling system to prevent overheating, while spark plug holes are where the spark plugs are installed to create the spark for combustion. The presence of antifreeze in the spark plug hole can indicate a leak or damage to the engine's cylinder head or gasket, allowing coolant to enter the combustion chamber. This condition requires immediate attention and proper diagnosis and repairs to prevent engine damage.
