2004 Chrysler Pacifica ProblemsTicking Noise From Engine
The engine may develop a ticking noise, often caused by a broken retaining pin on the rocker arm shaft. When the pin breaks, the shaft can spin blocking the oil passage the rocker arms (which causes the ticking noise). The rocker arm shafts, rocker arms, and pedestals (sold as a kit) are commonly replaced in order to correct this condition.
Carbon buildup on the valves may illuminate the Check Engine Light, indicating "Multiple Cylinder Misfires." The combustion chamber must be cleaned of carbon. There are updated valve spring retainers that will help prevent a recurrence.
Static discharge and/or loose wire connections could cause problems with the front power seat memory, seat heaters, and adjustable pedals. Revised seat modules are available that resist the affects of static discharge.
