The main reasons for engine oil water ingress are:

1. Damaged oil radiator leading to engine oil ingress

Damaged oil radiator

The radiator pipeline of the TEREX spare parts has broken, and water from the outside of the radiator can seep into the oil radiator, causing the oil to enter.

2. Engine water blockage and leakage leading to oil ingress

Engine water blockage and leakage

After several years of engine use, due to the corrosion of scale, some water blocks and rusts through, causing cooling water to enter the oil passage from the water channel and descend to the oil pan. This situation is also very common, so it is necessary to regularly check for water blockage.

3. Damaged cylinder liner sealing ring can cause oil to enter the water

The wet cylinder liner comes into direct contact with cooling water, and the sealing ring at the bottom of the liner can effectively prevent oil and cooling water leakage. In use, the sealing ring bears a certain amount of pressure, and sometimes poor cooling water quality can cause corrosion. After the engine runs for a long time, the sealing ring is prone to failure.

Engine cylinder liner sealing ring

Damaged cylinder liner sealing ring is a major cause of oil ingress, so when checking the cause of oil ingress, it is important to remember to check if the cylinder liner sealing ring is intact.

4. Cracks in the cylinder liner can easily lead to oil ingress

When the heated cylinder liner comes into direct contact with the cooling water, it is easy to produce cracks. Once cracks occur, the cooling water will directly enter the cylinder and enter the oil pan through the cylinder wall, which will cause the engine oil to turn white. Turning the engine oil white can lead to poor combustion, white smoke, and other problems in the engine.

Cylinder linder

In general, cylinder liners are not prone to cracking unless there is improper maintenance, such as in cold winter when the cooling water is not filled with antifreeze, which can cause the cylinder liner to crack. Another issue is that the hot cylinder liner comes into contact with relatively cold cooling water, etc.

5. Damaged cylinder gasket leading to oil ingress

The function of the engine cylinder gasket is to seal each cylinder, as well as the corresponding water and oil passages of each cylinder, in order to prevent oil from entering the water. If the cylinder gasket is damaged and the water circulation is fast, the water in the waterway will flow into the oil passage, causing the oil to enter.

Engine cylinder gasket

Damaged cylinder gaskets are also one of the important reasons for oil ingress. After each disassembly of the machine, try to use new Terex spare cylinder gaskets as much as possible to avoid oil leakage caused by cylinder gasket leakage and engine damage.

Engine oil water ingress can be said to be a common fault in internal combustion engines, which can be judged by observing the appearance color, oil level, and coolant of the engine oil. If water ingress is found in the Terex spare parts, it can also be inspected from several aspects such as oil radiator, water blockage, cylinder liner sealing ring, cylinder liner, cylinder gasket, etc. to determine the cause of oil ingress.
