Where are the most common locations of fluid leaks caused by a faulty ignition coil in Suzuki Alto?

A faulty ignition coil can sometimes contribute to engine sputtering and cause fluid leaks. Where should I inspect to find fluid leaks associated with a malfunctioning ignition coil in my Suzuki Alto, and what components are most prone to leakage?

While a faulty ignition coil doesn’t directly cause fluid leaks, the engine sputtering and misfiring it causes can contribute to conditions that lead to leaks in the following areas:

Spark Plug Area: If the ignition coil is not delivering a proper spark, the engine misfires, which may cause oil to leak around the spark plugs. Oil can seep through worn spark plug seals o r valve cover gaskets and pool around the spark plug area.
Valve Cover Gasket: The valve cover gasket seals the top of the engine, and a misfiring engine can increase engine vibration, leading to cracks o r wear in the gasket. This can cause oil leaks along the sides of the engine.
Cylinder Head Gasket: Continuous misfiring may lead to increased engine pressure and heat, which can cause the cylinder head gasket to fail. A blown head gasket can result in coolant o r oil leaks and may lead to engine overheating.
Engine Block o r Crankcase: In extreme cases, engine misfires and overheating can cause cracks o r damage to the engine block o r crankcase, leading to oil o r coolant leaks from these components.
Solution:

Inspect the area around the spark plugs for oil buildup.
Check the valve cover gasket for any signs of leakage o r cracks.
Monitor the engine for any signs of overheating, such as rising temperature o r coolant loss, and check for leaks around the head gasket.
