What Causes Oil on the Engine?
2 Answers
The reasons for oil on the engine: 1. The oil filler cap is not properly sealed, causing oil to leak out; 2. Incomplete combustion of gasoline, where unburned gasoline flows down the cylinder walls into the crankcase. It is recommended to check if the spark plugs are functioning properly; 3. It may be due to aging seals, which require timely inspection and replacement of new seals or gaskets. Otherwise, excessive oil loss may occur, leading to severe faults such as bearing seizure. An engine is a machine that converts other forms of energy into mechanical energy. It can refer to both the power-generating device and the entire machine, including the power unit. Engine types include internal combustion engines, external combustion engines, electric motors, etc.
As a driver with years of experience, I've seen many cases of engine oil leaks. It's usually caused by aging oil pan gaskets or valve cover seals, especially after prolonged exposure to high temperatures, which can make rubber components brittle and crack. It could also be due to a loosely installed oil filter or loose oil pipe connections. If not addressed promptly, the oil leak will worsen, leading to insufficient lubrication, increased component wear, and even engine overheating and failure. I remember helping a friend inspect a car that had been leaking oil for six months without attention—it ended up costing nearly ten thousand dollars in major repairs. My advice is to immediately wipe off any oil stains with a clean cloth and observe the location. If the leak persists, take it to a professional repair shop to replace the gasket—it's a small expense that can save big money. Regular maintenance checks on these seals are crucial; don't let small issues turn into major problems.
