Can a car still be driven if coolant enters the engine oil?

[ClaireRose]

Coolant entering the engine oil means the car cannot be driven. The symptoms include: 1. The engine oil level will rise; 2. The oil pressure will drop; 3. Water droplets will appear on the oil filler cap; 4. Water vapor and droplets will be discharged from the exhaust pipe; 5. Oil stains will appear above the engine radiator. The functions of coolant are: 1. To prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block when the car is parked in cold weather; 2. To prevent corrosion of metal parts and aging of rubber components; 3. To reduce the formation of scale, which could block circulation pipes and affect the cooling system's heat dissipation function; 4. To prevent the engine from overheating and ensure it operates at the proper working temperature; 5. To provide lubrication for the water pump thermostat and other components.
