If the oil level and pressure are both normal, the next step is to replace the oil pump. This is a complex job that requires some mechanical knowledge and experience. If you’re not comfortable doing it yourself, it’s best to take your car to a professional mechanic. They will be able to replace the oil pump and ensure that it’s working properly.
