3 Engine problem

Failure Date: 02/06/2003

The plastic part on the 4. 6 liter engine of my 1997 Grand Marquis failed in a remote part of arizona which resulted in complete engine replacement. I understand that all 4. 6 engines in crown victoria's, Mercury's, Lincoln's, and Ford trucks had this part on which many failed. Ford motor CO. So much as admitted that this part was unacceptable, because the plastic part was replaced with a metal one. However they decline to do anything if the car is beyond warranty. I understand that they had a hidden warranty for police cars and taxis with no mileage restrictions. Help !!!!!!!.

4 Engine problem

Failure Date: 05/02/2002

I puchased my vehicle new in 1997. The harmonic balancer had two major cracks which resulted in damage to the crank shaft which resulted in the vehicle requiring a new engine. This vehicle had only 68000 miles and was never involved in an accident. An independent mechanic who examined my vehicle explained he had never seen something of this nature in all his years of repairing vehicles. Since this vehicle has never been in a accident, all indications are that this is a severe manufacturing defect. If this engine had exploded, it could have caused severe injury to the driver.
