Five reasons for oil inflow

2022-09-08

 When the oil enters the water, if it is not dealt with in time, it will cause serious consequences. If the oil inflows lightly, it will cause deformation of important parts such as the crankshaft and connecting rod of the engine, causing the engine to shake, and in severe cases, the parts will be broken and the engine will be scrapped. So what causes water in the engine? Here are a few reasons why the oil gets into the water.
 
1. Engine water plugging and leaking
Due to the corrosion of scale, the water is blocked and rusted, and the cooling water will enter the oil channel from the water channel until it reaches the oil pan. This cause is common, so check for water blockages often.
 
2. The oil radiator is damaged
If the radiator pipe is damaged, the water outside the radiator will penetrate into the oil radiator, causing the oil to enter the water.







3. Cracks appear in the cylinder liner
When the cooling water is in contact with the working cylinder liner, cracks are easy to occur. Once cracks occur, the cooling water will directly enter the cylinder and enter the oil pan through the cylinder wall, which will make the oil white, and the oil will turn white. It will cause problems such as poor engine combustion and white smoke. Under normal circumstances, the cylinder liner is not prone to cracks, but in some cases, for example, in winter, the cooling water is not filled with antifreeze, which leads to freezing, which may cause the cylinder liner to crack.
 
4. Cylinder liner seal is damaged
Damage to the cylinder liner sealing ring is a common cause of oil ingress, so when troubleshooting the cause of the failure, be sure to remember to check whether the cylinder liner sealing ring is in good condition.
 
5. Damaged cylinder head gasket
 If the cylinder head gasket is damaged and the water circulation speed is fast, the water in the water channel will flow into the oil channel of the oil, causing the oil to enter the water. Cylinder head gasket damage is also one of the common reasons for oil inflow. After each disassembly of the machine, try to use a new cylinder head gasket to avoid engine oil leakage caused by leakage of cylinder head gasket.
