I have a 1998 Ford F-150 V6 4.2 liter with 92435 original miles. I woke up this morning and started my truck up and there was a loud knocking coming from the motor. My anti-freeze was low. I now have the same problem as earlier posts of a bent rod and need a new motor. I believe Ford Motor Company should have had this motor recalled and properly fix the problem. Glad they have the job because I am about to losing mine. Walking 6 miles to work today.

I was driving down the road and my spark plug blows out. It left me stranded on the side of the road.stranded. Then you have a cost of towing the vehicle somewhere. Then the repair cost.

I have now had 3 spark plugs eject themselves from the motor. To me there is a risk of fire being that the plug is exposed as well as fuel/fuel vapors since the plug is out of the head. There is also a manifold exhaust leak due to the studs breaking off in the motor. These heads are of poor quality and should have been recalled.

Incident #1 intermittent electrical contacts in engine bay affecting charging system, emissions, and drive systems. Ford dealer diagnosed as "bad alternator" and "bad wiring harness". after I brought it back without having repairs done, I cleaned and lubed all connectors. All problems went away. I ended up having to buy a new battery due to damage done by the faulty connections. The problems had been intermittent and progressively got worse before I cleaned and lubed all connectors, this problem cost me a battery, and almost caused me to wreck as the battery died at night on the highway. With no battery and no alternator, the vehicle stalled, lighting died, etc. Incident #2 leaking timing cover gasket and lower intake gaskets. At this moment the vehicle has 127K appx miles on it, and it is currently sitting as I will not drive it until it is repaired, all miles put on vehicle have been "light" miles (no heavy towing, no overloading of vehicle, no excessive speed, etc). Ford issued a bulletin stating that there was a problem with gaskets up until roughly 1/16/98. They then issued a customer satisfaction remedy that did not cover the full gasket set or all affected engine model years. According to the bulletin, my engine (mfg date prior to 9/97) is affected, according to their customer satisfaction remedy it is not eligible. In my book, this is something that needs to be the basis of a recall. Engines have died with as little as 50K miles on them, I have never had a vehicle that I was honestly scared to drive until now. I will most likely be performing my own repairs on this vehicle due to Ford's incompetence.

Driving the vehicle at a normal speed I started to lose power and the truck began to misfire.the problem had been known to Ford, because our mechanic received an E-mail bulletin from Ford directly. Which stated the problems with the F-150. I have copies of this bulletin. Needless to say I was fortunate that this did not occur on the highway because my son and I would have been killed. Because the truck just lost total power.

I was driving, and the truck started losing power, and sputtering, I finally got it to a mechanic and he found that there were 3 cracked coil pack assemblies. These were replaced and it runs fine. This could have been a bad deal if I had been in a situation pulling into traffic, crossing a rr track or something similar. This idea of individual coils on each spark plug is not a good idea, and dangerous. I realize there are a lot of miles on my truck, but this could happen at any time.
