Is it normal see engine oil spitting out as soon you take the filler cap off while motor is running?

It is not normal to see engine oil spitting out as soon as you take the filler cap off while the motor is running. This could indicate a problem with the engine's ventilation system, such as a blocked or faulty PCV valve. It is recommended to have the vehicle inspected by a mechanic to diagnose the cause of the oil spitting and to determine the appropriate repairs.
