Why would a 2008 Grabd Caravan 4.0L 50,000 miles odometer require a Rocker Arm Assembly replacement when the oil was replaced every 3,000 miles?.

You must ask your dealer and bring your maintenance records, they have engine info and bulletins about their problems. they can contact the engine plant. you must ask what they will do after 7 years at that mileage,what other instance is there of this concern? is there a parts update.?

If it is about time for a oil change leave out one quart of oil and add a bottle of Lucas Engine Oil Stabilizer or if just had done remove one quart then add the ticking will go away I promise. I can make this promise because I have seen and heard this product work. My friends vehicle was ticking like a sewing machine changed his oil left out one quart added the Lucas and with in 30 - 45 minutes of idling the tick was gone.
