Hello. My name is ***** ***** I will be assisting you today. On these Cadillacs, a common issue that causes the oil light to come on, is a faulty oil pressure switch. I have come across many that actually leak through the oil switch connector end. You should have the switch inspected to see if this is the issue. Also, you should check the oil level to be sure that it is sufficient. With the valve cover leaking this is a very possible cause. I would also have the oil pressure tested to make sure the issue is not a failing pump. If the pump is the issue, the valve cover nor the oil pressure switch will fix the issue. Although, from my experience, the switch is usually the cause. Just a moment, please, while I retrieve valve cover gasket replacement information.

This motor is a northstar. The same 4.6l that you would have in your vehicle.
