Hello. Most of the time when this light comes on with an engine noise like this it is caused by a failing oil pump. If the pump fails internally then this will occur. It can also be caused by a failure in one of the main bearings in the engine, which will cause low oil pressure. I would start by draining the oil and changing the oil filter. If there is any metal in the oil, then you have a serious engine failure. If the oil looks fine, then it may just need the pump. If you are going to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your Oil Pressure Light and knocking sound.
