1998 Ford F-150 Engine Problems

“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.”

“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.”

“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.”

“Traveling home towing my boat and another spark plug blows out. Tried to fix on the side of the road for 3 hours in 90 degree heat. Had to wait to get my truck towed and then another for my boat.”

“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.”
