Timing Chain - Repair or Replace
Your engine's timing chain can stretch over time resulting in a check engine light that comes along with excessive noise from your engine's timing cover. If the chain has broken, which is a rare occurrence, the engine will not start. If your 2003 Ford F-150 has high mileage along with any of these other symptoms, contact our service department for expert diagnosis.
