Do all second-generation EA888 engines burn oil?

[StBradley]

Not all second-generation EA888 engines burn oil. Here are the specific reasons for oil burning: 1. Worn valve seals: Valves are used to prevent oil from leaking into the combustion chamber, but over time, they can wear out or age. Severe wear can affect the sealing of the valves, making it easy for oil to burn. 2. Excessive piston clearance: When a car is used for a long time, incomplete combustion can cause carbon deposits to accumulate on the piston rings. If not cleaned for a long time, this can widen the gap between the piston rings and the cylinder, allowing oil to flow into the combustion chamber and cause oil burning. In severe cases, it can even lead to engine seizure. 3. Driving habits: Frequent rapid acceleration and prolonged high-speed driving can easily damage the lubricating oil film, leading to poor engine lubrication and wear on certain parts, which may also result in oil burning. 4. Excessive oil level: If the oil level is too high and exceeds the maximum mark, the excess oil can easily enter the combustion chamber (due to excessive internal pressure) and form sticky carbon deposits.
