2002 Ford Explorer started a little knocking passenger side front of motor. Knocking worse now and oil pressure gauge fluctuates at idle
What could it be. Hoping I change oil and the oil pressure sensor and I might be good. Wife not sure if it was fluctuating previously or not.
Is it a 4.0 engine? If so it is a SOHC design. There is a cam chain for both sides of the engine. Could e the tensioner. Have a mechanic check. If it is the rear one, the engine has to come out of the vehicle to repair.
Have you checked the oil level?
