Filed Apr 5, 2017 · Engine · 89,000 miles · FL

I was driving down interstate 75 and suddenly I lost power and had a extremely loud piping noise coming from under the hood . I stopped immediately and checked under the hood I could not tell with the engine off so I restarted it and inspected it and found that my number 2 spark plug had blown out of the cylinder head after buying a new coil pack and spark plug set I discovered that all the threads had blown out of the head with the spark plug and after changing one of the other spark plugs I found that it was barely holding in .I think that the heads design was poor and weak and is s safety hazard.

A major loss of power while towing a load. The loss was significant enough the first time that the truck could not shift into higher gears. Could only manage 55 MPH max. When I arrived home, took it to my local dealer to have it repaired. They had it for 10 days and were unable to locate any problem. They reprogrammed it, again, and gave it back with a significant bill. The problem persists. The next time I used it to haul a load, it did it again, only this time I was attempting to pass. Could not complete pass and fortunately was able to get back in behind the vehicle I was trying to pass and avoid a head on collision. It's dangerous! The problem is subtly worsening. Since that last episode I did some research of my own, besides contacting ford corporate direct numerous times and the dealer, I discovered there is a history of all sorts of trouble with their v 10. I discovered last night that many others have experienced what I am attempting to correct, all with the same results, no repair. All ford would do is to continue telling me over and over to just go to my dealer as they know all. They do not! I am still in contact with my dealer regarding this problem with no options available. I am about to replace a few parts myself in an attempt to correct it myself. Per my research, it became very apparent that ford's computer for engine operation and diagnosis is flawed as there were never any number indications revealed to indicate the source of the problems, per numerous others as well as myself. It is now obvious that ford is well aware of this problem but is covering it up instead of addressing it. This problem also appears to be happening to vehicles much newer than mine. This vehicle is dangerous when under load. There may already have been accidents caused by this chronic problem, I do not know. But I do know that this vehicle is a disaster waiting to happen.

I own a 1999 ford f-250 pickup truck with a 5.4 liter triton v8. My truck has 103k miles on it. I had just replaced all the spark plugs less than a year ago. Last week on my way to work, I heard a pop and the engine started making a bunch of noise, lost power and quit. Luckily, I was able to pull over into a parking lot and call a tow truck. Once getting it home, I noticed that a spark plug had blown out of the engine. My #3 spark plug on the passenger side blew straight out of the head and destroyed the ignition coil pack. After doing much research over the internet, I've found this to be a very common problem with these ford engines and ford won't do anything about it. This will cost well over $3000 to fix. It's a good thing my engine quit so soon, or I could have had gasoline spray out of the open cylinder and cause a serious fire.
