I have had 2 spark plugs blow out of cylinders, once while driving and once while it was idling in the driveway. The spark plugs were torqued in using a torque wrench, but work loose with time. I have to check the tightness of the plugs every six months or they will loosen up and blow out. I have helicoils put in for the threads, but it is $400 each time it happens.

Own 2000 F150 with 4.6 motor. Right rear spark plug blew completely out on trip from Wyoming to Vermont. On a Sunday so had to complete the run, fixed it with a spark plug insert and replaced individual coil that was blown apart by the plug, but truck has not run right since. What is being done about this as it seems to be a very common complaint ?

2000 Ford F150. Blew no. 3 spark while driving. It blew at partial throttle, 45 mph. Truck has been properly maintained, never had this happen on any other car I ever owned. Come to find out this a common problem on Triton V-8 engines. I've owned cars with aluminum heads before so for Ford to claim its a torquing problem and the fault of the owner is disgraceful to all the people that maintain their own cars. Fortunately the fire was only temporary and went out when I stopped the truck and killed the engine, but there obviously had been a fire at some point. This is the same truck that has already been recalled once, still have a burn mark on the master cylinder reservoir from where it almost burst into flames in my driveway one day, thank god I just so happened to have the hood up to replace my coolant when it happened, or the whole truck would have burnt down, I managed to pull the fuse before it did, but for this to happen on top of that is ridiculous.

My 2000 Ford F-150 w/ a Triton 5.4 L engine (: ) blew the #3 spark plug. There were no unusual events leading up to the failure. I took the truck to the dealer and they wanted to charge me $3000 for a new head or $1000 for insertion of a helicoil. I know that this is happening on many trucks like mine. Why is Ford not being forced to take responsibility for this failure? it is obvious to me that it is not improper installation of a spark plug, a few too many coincidences for that I think.

2000 fleetwood pace arrow motorhome with Ford Triton V10 enginge: At 32,000 blew a spark plug out of the head. Ford dealer quoted me $6,000 to replace with new/improved head. I can replace the whole engine for less than $3,000. This is incredible and something needs to be done. Even the tow truck driver that towed me to the dealer said his Ford truck with a V10 recently blew a plug as well. I own four motorhomes all with the Ford Triton V10 engine. The company I used to work for had six motorhomes with the Ford Triton V10 and had four spark plug blowout incidences while I was working there. Something needs to be done about this. It is unthinkable that a company can get away with peddling crap to customers and then charging them $6,000 to fix this problem!!! contact oscar at don kott Ford in carson, ca to confirm my estimate. Do something, do something do something! thank you very much.

: the contact stated while driving 40 mph, the vehicle began to lose power, accompanied by a knocking noise coming from the engine compartment. The vehicle was taken to a service dealer, who determined that the # 2 spark plug had blown out of the head. One year prior, the # 7 plug had also blown out of the head, and the dealer replaced the head, however the problem persisted.

I have had 3 spark plugs eject from my 2000 F150 5.4L in the past 3 months. So far, repairs have totaled $150, but the last one took the threads with it. Estimate to fix this one is $400 with a specially made repair kit. As most know, this is "the problem that must not be named". everyone knows it exists, Ford doesn't want to deal with it.

I bought a 2000 Ford F-150 with the 4.2L V6 engine and I now have to replace the engine because of a defect that Ford is aware of I have done a lot of research on this issue and have found thousands of other 4.2L V6 owners that have the same problem and Ford will not do anything about it I have asked Ford for help in the replacement of the engine. I was given excuses and told to go away and buy a new engine. I tried to make a formal complaint to Ford but I was told that it would be brought to their attention with no paperwork filled out. I am very upset with the way a loyal customer of Ford is being treated. I now have to replace the engine but cannot afford to. There is a defective seal or gasket that leaks antifreeze into the engine and causes pistons to break rod to be pushed out of the engine and several other interior engine parts to break. Ford Motor Company will not replace the engine even though it is a defect on their behalf not the buyer. Ford does not tell new customers about the problem and continue to sell the vehicles knowing that the engine is defective. All I would like is for Ford to take responsibility for their engine and replace it with a different engine or make sure that the new engine will not cause the same problem.

2000 Ford F-150 4.2L V6 head gasket failure. My vehicle began overheating and smoking white smoke about 2 weeks ago. Also noticed that heater would only put out cool air, unless the engine started to overheat. Ended up needing a new head gasket, which come to find out are notorious on the 4.2L V6 motors. I caught it before any motor damage was done so no added expenses were needed. However it still was not a cheap fix. I know of at least a hundred 4.2L V6 F-150 owners who have had this problem and most would be willing to help further an investigation. I do still have the old gasket if needed.
