What are the most common areas where engine sputtering and fluid leaks occur in Suzuki Alto?

If my Suzuki Alto is sputtering and leaking fluid, which areas should I inspect to identify the cause? Are there specific components, such as the fuel injectors, spark plugs, o r hoses, that are more prone to causing both sputtering and leaks?

The most common areas where engine sputtering and fluid leaks may occur in a Suzuki Alto include:

Fuel Injectors and Fuel Lines: Faulty fuel injectors o r damaged fuel lines can lead to fuel leaks and sputtering. Leaks in the fuel lines are often visible as wet spots along the fuel rail o r under the car.
Spark Plugs and Ignition Coils: Worn-out spark plugs o r faulty ignition coils can cause engine sputtering by failing to ignite the fuel properly. These parts can also lead to incomplete combustion, which can stress the engine and cause oil o r coolant leaks.
Valve Cover Gasket: The valve cover gasket seals the top of the engine, and when it wears out, oil can leak out. This oil leakage can cause sputtering if the engine is starved of oil o r overworked.
Head Gasket: A blown head gasket can cause both coolant leaks and engine sputtering. Coolant may mix with engine oil, causing a milky appearance in the oil and overheating, leading to engine misfires o r sputtering.
Radiator and Cooling System: If there’s a coolant leak due to a damaged radiator o r cooling hose, the engine may overheat, causing sputtering and potential fluid loss.
Solution:

Inspect the fuel injectors, fuel lines, and spark plugs for damage o r wear.
Check for oil and coolant leaks, particularly around the valve cover and head gasket.
Regularly monitor engine temperature and coolant levels to catch any overheating issues early.
