One problem related to crankcase (pcv) has been reported for the 2002 Ford Expedition. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2002 Ford Expedition based on all problems reported for the 2002 Expedition.
Started as small oil leak. After placing dye in crankcase found drivers side head gasket leaking. I am having both head gaskets replaced for 17k. There is only 49k on this truck with all normal driving. From other complaints that have been posted I do not understand why Ford has not been made to respond to the problems with their product line. This problem has been in complaints since '98. Isn't time that some accountability be taken by the manufacturer?.
