What will happen if oil level is too high?

If the oil level in an engine is too high, it can lead to foaming, which reduces lubrication efficiency and can cause increased wear on engine components. Additionally, excess oil may cause pressure buildup, potentially damaging seals and gaskets. In severe cases, it can lead to oil being pushed into the combustion chamber, resulting in smoke and decreased engine performance. Regularly checking and maintaining the correct oil level is crucial for optimal engine health.
