Why does the engine oil comes out from the breather port after Daewoo engine overheat?

When a Daewoo engine overheats, it can cause increased pressure and temperature within the engine, leading to the breakdown of engine oil. This can result in the formation of gases and vapor that escape through the breather port. Additionally, excessive pressure can force oil out of the crankcase, causing it to leak through the breather. It’s a sign of potential damage or failure in the engine's sealing components.
