Plastic intake manifold failure on a 1996 Ford Thunderbird v8. Part failure was preceded by a "check engine light" and "low coolant" light. Turns out that Ford had put out "service bulletin" in 1999 and followed up on it in 2001 on this issue (97m91) yet they never notified any owners. Cost of repairs for this part will be around $1,000 yet Ford will not do anything willingly to rectify the situation. Failure of part could lead to catastrophic engine failure if not corrected.
Ford recall not honored - intake manifold http://www.bigclassaction.com/class_action/ford_manifold.html upon acceleration, smoke came out of under hood & I believe engine light came on. It all happened so quickly. Made it to the nearest lot, where I could pull off the road. All coolant leaked out. Had to call for tow. Mechanic did coolant pressure test, and showed only leak was at back of engine. Had to pull transmission to get to it. Water pouting out back of engine but no freeze plug blown, traced backward to intake manifold crack that never showed up on intial pressure testing. I was charged over $750. For repairs. Called dealer to check on warranty (expired 1200 miles earlier) and recalls. Said there were none. Just recently discovered the recall at an autozone website, and contacted dealer about it. He said to send in original receipt & Ford would reimburse. …
In febrruary 2003, my 1996 Ford Thunderbird 4.6l started spewing what I thought was smoke from the engine compartment. I was just at my driveway and pulled in. After opening the hood I realized it was not smoke but coolant that was being sprayed all over the hot engine. I had the car towed to friendly Ford in las vegas, nevada, where I had bought the vehicle, and after some discussion, they replaced the intake manifold under a TSB. On 6-2-04, some 16 months later, the intake is again leaking. After doing some research, I found that the part they put on the car is not the recommended part as stated in a letter from Ford motor company in flint, michigan,dated December 2001. The part which Ford states is the replacement part is f6az9424aa. The part listed on the repair invoice is f8az8424aaa. The part actually installed on the car has a part number of ae9424ca. …
Head gaskets failed ruining my cylinders as well while driving on the highway with my children. Barely got the car home with a cloud of white smoke. I cannot afford to fix this the car has been sitting for almost 1 and a half months, and I still owe 5900 dollars on it. I have to ride my bike to work over 3 miles each way and rent a car for the weekends costing me a fortune. I believe they need to pay for my engine to be rebuilt especially after reading all the articles of how the 3.8 litre v6 engine has failed continuously throughout the years and Ford has known it. I love fords and have never drove anything else. I am in a serious bind and need help for something that failed due to a defective part. Thank you for listening and I hope Ford gets the message.

Intake manifold(plastic) cracked again;overheated and burnt me this time also causing serious damage to car;very costly which I guess we the consumer will have to bear.
