rattling noise under the hood

Hello, the cold weather is not something I am thinking about here. You continue to drive the vehicle even with the check engine warning lights and engine oil lights illuminated. These are warning lights indicating that damage is occurring and will continue to occur until the vehicle is repaired properly. It may be too late, but stop driving the vehicle and have a checked right away. You could be simply low on oil, or there could be an internal engine oil lubrication concern that has caused damage already.
