I was driving on interstate 5 when there was a loud pop followed by rapid popping from the engine. At first I thought it might be a flat and pulled onto the shoulder, but the noise continued even though I was stopped. I opened the hood and at first (based on the sound) thought it might be the exhaust manifold. I was towed to the nearest Ford dealer where the problem was determined to be a blown spark plug which had stripped the plug's threads. The dealer inserted a heli-coil and after a tow, an overnight stay at a nearby motel, 5 hours of waiting the next day and $415 in repairs I was back on the road. I have since done some internet searching and have come to find that this is a very common occurrence with the triton engine and has been so for several years due to insufficient material and threads.
Intake manifold leak. Plastic part cracked. I just had repair made and was told Ford has a problem with this type of manifold. My truck is a 2001 f150 with 90,000 miles.

Took truck to dealer after hearing low end ticking sound and mil light, told it was tensioner and manifold spacer. Picked up truck 8 days later and still had problem, returned and told by head mech. That it was a normal sound. Drove home and it was missing badly. Returned was told had a bad plug, truck is still ticking and loudly. Dealer washed hands of problem.
Have 2001 Ford f150 supercrew 5. 4 engine with 51k miles. Accelerated to enter highway and heard loud "pop", then lost engine compression and heard loud un-muffled engine noise eminating from the engine compartment. Having a fair knowledge of cars, I thought I blew the head gasket, but upon inspection by a local dealer (cosway Ford in stafford, NJ) was told I blew a spark plug and it is not a covered item under my extended warranty. The service tech seemed to know right away what the problem was when I described it, leading me to believe this is a very common problem. As I gathered, upon researching the internet, this is more than common, it is a manufacturer defect in the aluminum cylinder heard. I am 33 years old and have been around cars for a long time and have never heard of this problem. I bought the truck new and babied the vehicle. It seems this problem is limited to those year 5. 4's that use the flawed 4-thread cylinder head, as to why in 2003 Ford changed the design to 8-threads. Please help force Ford motor company to fess up and recall these vehicles. I understand it can happen again. This repai will be costing me $501. 80, plus the rental of a car (was far from home on vacation).
While driving home from work today, approaching the on-ramp to the 280 on sand hill road in menlo park, CA. The 2001 F-150 5. 4l pick-up with 75,000 miles, started making a loud popping sound while driving about 35 mph. I pulled the truck over to the side of the road immediately and turned the engine off. The car was towed by flatbed to the local shell gas station repair shop to be seen by the mechanic in the morning. The mechanic indicated that the #3 plug on the passenger side of the car had come out of the head, the threads to the spark plug stripped. He was unable to get a new plug into the head and wanted my approval to spend about 5 hours or $750 to remove the head and inspect the cylinder head for a possible stripped socket. The Ford dealership separately quoted me $1,010 for a new cylinder head and the Ford service adviser at the palo alto Ford dealership quoted my an estimated 12 hours to tear down and remove the head for inspection. The hourly rate quoted is $105. I checked with another local auto repair shop, where the mechanic told me that the blown plug and stripped head was a common problem. He agreed that the five hour estimate to remove the head sounded right (why is Ford quoting me 12 hours?).
