The timing chain can not be repaired, it must be replaced. To do this you must disassemble the front of the engine. The fan, belt, dampener, water pump and timing chain cover must be removed to gain access to the chain.
it pays 8 hours labor. so depending on the shops labor rate should be a little under $800.00. call ford on timing chain and all gears and a gasket set
