Ford Oil Leak

According to Ford, some of its 1999-2002 vehicles with V8 engines may leak or weep oil from the right rear or left front of the engine. Affected vehicles include 1998-99 Navigators; 1999-2001 Econolines, Expeditions, F-150s & F-Series Super Dutys; 2000-01 Excursions and 1999-2002 Crown Vics, Grand Marquis, Mustangs & Town Cars. Add a trace dye to the crankcase and use an ultraviolet or blue light inspection lamp to find the leakage point. It will most likely be found emanating from one of both cylinder head gaskets. Ford attributes the leak to either metal chips between the head gasket and block, chip debris between the cylinder head and gasket or damage to the head that occurred during manufacturing. The affected cylinder head should be removed and closely examined. If chips are visible, but the head isn't damaged, they should be blown away with compressed air, the head and block cleaned and the head gasket replaced with a revised service designed. If the cylinder head is damaged, it must be replaced.
