I have a 99 Chrysler Concorde with the 2.7L and 150K miles. It has a blown head gasket. I started disassembling the engine and found that one of the timing chain guards broke off and started biting into the cylinder head and water pump. Besides the head gasket, cylinder head timing kit, and water pump, is there anything else that I should replace such as the oil pump?
Thanks,
