Engine Exhaust System problems of the 2001 Ford F-150



Eight problems related to engine exhaust system have been reported for the 2001 Ford F-150.

car   Engine Exhaust System problem 1
Failure Date: 05/19/2012

I was driving home and all of a sudden there was an explosion under the hood and it sounded like part of the exhaust system gave way. I pulled over and found out that a spark plug had blown out of the head. The only one to ever touch the engine was Ford and that they had replaced a spark plug several years ago. I got on line and found out there are literally thousands of these spark plug ejections. I was wondering if there was a recall on the problem ? the fact that the super-heated air and mixture fuel spraying all over the underneath of the hood is a extreme danger, it would seem that would be a safety recall.

F150 2001 Ford lightning 5. 4 trition engine. Sparkplug shoot out of engine. Defect in aluminum heads. I had a helicoil put in and it broke down 7 months later, and now I have to buy a re-muf.

Ford has a defect in there triton engine heads and there not doing nothing about its costing custermer thousands of dollors, and Ford doesn't care. Frustrated costurmer. James vega 407-286-6295.

car   Engine Exhaust System problem 3
Failure Date: 06/05/2010

The contact owns a 2001 Ford F-150. The contact started the ignition and light grey smoke emitted from the exhaust. The failure was intermittent and became progressively worse. The vehicle was taken to an authorized dealer three times for the identical failure. The catalytic converter and engine heat control sensor were replaced at the owner's expense. The failure continued after the repair was performed on the vehicle. The failure mileage was 118,042.

car   Engine Exhaust System problem 4
Failure Date: 01/25/2009

I have a Ford F-150 2001 with triton 5. 4 v8 I started my truck and heard a loud pop and then what sounded like a very bad exhaust leak. Come to find out the back sparkplug on passenger side blew out. I had to have a new coil new plug and helicoil installed.

car   Engine Exhaust System problem 5
Failure Date: 05/18/2008

In January I had driven my f150 to the store, when I returned to it in the parking lot and started it I heard a loud pop from under the hood. This sound was followed by a loud backfiring sound upon adding a few rpm's to the engine. I shut it off to inspect and discovered the far rear spark plug had been shot clear out of the head and was lying loose inside the engine compartment. The spark plug and the head each had enough threads left for the plug to reset. The coil was damaged and needed to be replaced. Three days ago (5/18/08) I started the vehicle again heard the same pop and the same backfire sound. Upon inspection this time I found that although the plug had not come out of the head this time it was clearly loose. There are no longer usable threads on either the head or the plug and I have been quoted $2500 (discounted rate) to repair a vehicle that has only 78000 miles on it and that I owe $16000 and can't even trade in now. I have done extensive research and have found that this is a very common complaint with the Ford tritan v8 engine and that Ford has not chosen to remedy this defect.

car   Engine Exhaust System problem 6
Failure Date: 04/13/2007

A spark plug blew out of my Ford F-150. Did not know until recently that this problem occurs a lot in Ford truck motors. Engine does not really run now because it would probably catch on fire from exhaust flames. I do not know what I have to do to get the problem fixed, but after reading multiple complaints, I am led to believe I will be paying roughly $5,000 to get the problem fixed.

car   Engine Exhaust System problem 7
Failure Date: 12/20/2004

This is a 2001 Ford svt lightning that has been a victim of a blown spark plug. This is a common failure in these triton motors. In the new groups, it is speculated that this occurs for two reasons. 1) a design error in the cylinder head. In the pre-2003 5. 4 mod motor heads, there are a total of 4 threads. Ford has realized this problem and corrected the 2003-later heads with 8 threads to hold the spark plug in. This problem effected all triton 5. 4 motors and the problem has shown up in 5. 4 liter motors in other non-lightning trucks and expeditions. 2) there have been many instances where Ford customers have found that the spark plugs have been very loose in these triton heads. This is not known whether this is from a lack of threads or being loose from the factory. Either way, in this day and age in automotive technology, the requirement that a customer has to check the torque on spark plugs is unrealistic. Other factors to consider: my lightning is a 2001 model with 15,000 miles on it. Obviously it is infrequently used. There is a performance chip that does not add boost. In essence, this truck is pampered. The head failure occurred during normal driving on a slight incline go the speed of traffic. Approximately 35 mph. There is no detonation issues with this vehicle. Prior to this failure the power train had no chronic issues such has unknown supercharger noises, engine ticks/knocks, ignition, fuel issues or smoky exhaust. Ford will not cover this damage and failure even thought this happens frequently in F-150 Ford trucks running this engine.

car   Engine Exhaust System problem 8
Failure Date: 04/02/2001

Since the purchase of this brand new vehicle, the exhust has been black. The dealer's computer says that nothing is wrong, I think it is an epa violation, but because state emissions is not a required test in south carolina, they say that since it's not a saftey hazard, there's nothing they can do about it.
