F-150 LX 4.6L V8

  • Automatic transmission
  • 94,146 miles

A D V E R T I S E M E N T S

I was traveling down the freeway at 60 miles an hour when I heard a loud noise under the hood followed by a lot of clattering. I was 135 miles from home. So I pulled off the freeway onto the shoulder. I looked under the hood; starting from the grill searching to the rear looking for the problem. I first thought I had broken the belt, then I saw a sparkplug lying on top of the engine and the coil bracket broken and the coil lying on its side.

I did not have any tools with me, so I limped to an auto parts store thinking I could just replace the coil. The manager said it may be worse than just replacing the coil. He had spoken to others Ford owners that the spark plug was stripped from the engine. He even said one of his customers had just purchased a low mileage 2007 Ford from a dealer and asked to have a tuneup. He was told that it would be $3,000.00 for the tune up because the Triton engines don't hold their spark plugs. He would have to have the engine bored and new sleeves put in.

Ford appears to be knowledgeable of their defects or at least their mechanics are. There should be a recall of all Ford Triton engines.

I am one of the people who have had the original factory spark plugs eject from the engine, which indicates there is a defect with the engine & cylinder head design.

Where I work, four of us have the same year truck, three of us had the same spark plug ejuct problem! The fourth guy only has 40,000 miles on his truck, so were all waiting for it to happen to him! Just another of Fords better ideas-I DON'T THINK SO!

Ford Dealership in Georgetown TX wants $5000. to replace cylinder head after spark plug blew out of the engine. These are original spark plugs and NO one should have to incur this type of expense. Was Also advised that they may have to long block the engine at my expense. Ive been a loyal Ford man for 15 vehicles. Notwithstanding if Ford doesn't step up, I'll move on!

F-150 Xlt Lariat 5.4L V8

  • Automatic transmission
  • 72,000 miles

First plug blew #7 10/2009 the day after an oil change at the dealership, shamed them into repairing it for parts, then on 5/2010 I blew plug #4 this one cost $700 because I needed an insert. I asked them to check all of my plugs because I was told that they would only blow if they were lose. Then 10/2010 (1 year and 4 days later) plug #7 blew again, not covered under the warranty from the repair because it was 4 days after the 1 year warranty,so I had a local reliable mechanic repair it and replace all of my plugs, he said there were 3 plugs that were lose, really only 5 months ago they were checked, anyway so far so good. I did forget to mention that my local dealership told me that they have a truck in about 2 to 3 times a month but this is not considered a flaw or recall problem.

Really! I like this truck and I can't afford to buy a new one, b I am afraid to take it on a long trip.

my F150 4.6L blew out plug and burned hole in pistion head needing new motor 3500bucks if they have more threads in cylinder head there would be no problem then they could call it a trition and be pride of it problem is fixed more threads on newer engines but for people like me with 2002 4.6L have to bite the bullet if they changed the new engines they should take care of people who had problems with older engines no problems with engine until plug blew out then all hell broke out

  • Automatic transmission

Just installed a new motor 3.5 months ago and this happened. I'm pissed right off. After talking to mechanics and the place I got the engine at, they tell me this is a common problem with these engines. Why the f#ck doesn't Ford pay up and do a recall? There reputation is already f@cked up. According to stats on the internet, there are some 20 million odd customers that have experienced the same thing.

As I search the issue with my F150 I have realized that the blown out Spark Plug is a huge issue. Ford needs to step up and fix this with a recall and make it right.

This is the second time now and it was the same plug. It was repaired by a very reputable mechanic and he used the insert instead of the helicoil. Still blew out at 55 mph with out any rawhiding of the truck.

Update from Mar 17, 2011: FIXED YET AGAIN. THIS TIME WITH INSERT. MAYBE THIS WILL DO THE JOB

F-150 Lariat 5.4L Triton

  • Automatic transmission
  • 175,000 miles

Just before Christmas eve, and boom goes the engine.doing 75 on rt 80 with 40 miles to go to get home,I limped home. The plugs have been in for 75000 miles so Ford cant say they were installed wrong but they can say the problem was fixed after 2004. I replaced it with the Cal-van kit and it fixed that issue but I here a death knock on the lower end right in that area ,probably rod bearing and probably caused by bthe compression relief when the plug busted out like a scud missile,thanks ford.

Update from Feb 22, 2011: Well its not the lower bearing and that sucks because its a wrist pin, great, cant fix that by pulling oil pan, running it till it blows and buying a Chevy.. The kit I used worked great, I also bought the scope for looking inside the piston chamber when I did the work.. 384.00 total and 45 mins of my time that I will never get back,,,THANKS AGAIN FORD!! PS,As soon as it goes I'll have a kit for sale to replace the poor workmanship of Ford engineers great NO THREAD IN HEAD FOR PLUG problem

spark plug shot out of head 30 miles from home. stripped threads due to weak aluminum head. no forewarning or preventative measures to keep this from happening. definitely a fire risk, good thing I was 1/4 mile away from a repair shop. this should be a ford recall as it appears to be a known reoccurring problem.

I can't wait to talk to the ISO about this lack of quality .Is Job One to Screw America? This is a lack of control in the material div.Come on Ford .70,000 miles is not what I would call a life time . and When they say 100,000 miles before a tune up . Why would I check the plugs to see if they were tight.

This happened to us twice on a move across the county. I can't believe the amount of info on this. Three different Ford dealers knew all about this problem, but Ford refuses to accept responsibility. We are done the Ford and trying to get the word out to the rest of the world. Even though this issue appears to be well known on line, we didn't know about it until it happened to us. Ford must be spending a lot of money to keep this quiet,
