One problem related to crankcase (pcv) has been reported for the 1996 Ford Windstar. The most recently reported issues are listed below.
Head gasket leaking into engine. Coolant entering cylinder and crankcase, producing steam out of the exhaust. Contacted Ford dealer for repair estimate and was quoted $600+ for labor and additional cost for parts. Have discovered through this website and others that this is a common problem with Ford 3. 8l v6 engine and that Ford has helped with costs on 1995 vehicles, but not 1996. Should not be having this problem with only 79000 miles on vehicle, and since it seems to be common, manufacturer should cover costs. Last Ford I will own.
