Manifold/header/muffler/tail Pipe problems of the 1999 Ford F-150

Lower intake manifold gaskets keep blowing, as well as the head gaskets I only drive Ford's, so Ford please fix this for us loyal owners please.

I was cruising along the highway at approx. 68 mph, then I heard a loud pop. Then immediately after sounded like I was driving without an exhaust manifold almost. Once I felt that I had lost a lot of power I then realized what happened. I was luckily 2 miles away from a town and babied it into a store parking lot. Upon looking under the hood I found the sparkplug ejected from cylinder #3 and busted the ignition coil. Now what if I was int the middle of nowhere with my wife and daughter? worse yet what if the vehicle had caught on fire with them as well? due to fuel vapor spitting out the sparkplug bore and getting ignited from the loose ignition coil. I myself and others have been fortunate that these things did not happen, but I can't say for everyone. This is a very big issue that has been ignored and is a potentially huge safety hazard as well.

The contact owns a 1999 Ford F-150. The contact stated that the exhaust manifold started breaking away from the vehicle. The contact took the vehicle to a mechanic and was informed that the bolts holding the manifold in place had rusted and broken off. The contact was also informed that this was a common failure. The failure mileage and current mileages were 291,000.

I noticed a ticking noise which sounded like an exhaust manifold leak for the past few days and just today I was taking off from a stop sign when the spark plug blew out of the head creating a loud knocking/ticking noise. I have not had it fixed yet, but from what I understand this can create engine fires which can be a major safety hazard.

I own a 1999 Ford F-150, 5. 4l v-8 triton. I recently had a tune up in December 2010 with all eight spark plugs and wires changed out for a mere $700. In Feb 2011, as I was taking my children to school, I heard a loud pop then my engine started to sound like a tractor without a muffler on it. I pulled over and called wrecker to return the truck to my house, out of pocket $60, not knowing anything about engines. I called the repair center who then had it transferred back to their shop for repair. The #8 plug had completely shot out ripping the coil with it. They fixed that, now two weeks later, the #7 plug is fouled according to the mechanic. This is a major safety concern and a financial burden, as I read other statements of the same defective issues with Ford, considering fire could have been a result. Please re-open this investigation and force Ford to issue recall so that those of us who are financially strapped can have our trucks repaired. Otherwise I can assure that I will never buy Ford product again.

Spark plug blowout on 1999 Ford f150 with 5. 4l triton v8. It seems to be a very common problem with the Ford modular engines. Today, I heard a loud pop come from my engine bay as I accelerated and then the sound of what seemed to be a massive exhaust manifold leak. Upon further inspection, I found that the spark plug on the rear passenger side of the engine had ejected and broke the coil with it. I was lucky that it had only damaged the threads on the spark plug and sheared the coil at its mount, instead of damaging the threads on the head, but from reading the multiple other stories online about this happening, it seems that I am luckier than most. I was able to repair it by replacing the spark plug, boot, and coil, but from what I have seen, most people have to replace the head when it happens. I don't see why there has not been a recall since it can cause an accident due to scaring a driver when they hear a loud explosion in the engine when it happens, or possibly killing someone as fuel/air vapors escape the engine and the spark plug could possibly ignite it outside the engine, and being right next to the fuel rail and injectors, possibly cause massive fire damage with its occupants still inside the vehicle. Please tell Ford to recall this problem. I see the fix being as simple as putting stronger thread inserts to prevent the spark plugs from ejecting. Its ridiculous us as car owners should have to continuously pay big bucks for a faulty engine design that Ford refuses to acknowledge or fix.

Spark plug blew out of #3 cylinder in the head of a 1999 Ford F-150.

The #4 spark plug was blown out of the head. I was told my mechanic that it was an ongoing problem with my 5. 4l v8 triton motor but Ford will not fix the problem. I purchased the vehicle used two months ago and was never inform at time of the problem. I would never have made the deal if I would have know about this .

Spark plug spit from cylinder head.

Drove my F-150 truck to eat then when I came out I drove it about 100 yards and stop and did about 15 minutes shoping at home depot when I came out and started it it made a bang. It sounded like a hole in the tail pipe. When I took it to the dealer they said it was a cylinder head from a blow spark plug.

Replaced exahust manafold, my repairman said many Ford owners had same problem.

The consumer took vehicle for service because of a ticking noise heard on vehicle. The dealership indicated that the ticking noise was coming from the catalytic converter, and the head gasket had blown. Which resulted in an oil leak into the exhaust manifold. The dealership replaced the catalytic converter and the head gasket; however, the ticking noise still exist after the repair was performed. Within 300 miles after the parts were replaced, the spark plug came out of the right side of the engine head which resulted in engine failure. The dealership refused to honor repair warranty and perform any further service on the vehicle.

Smelled burning oil. Looked under truck and noticed oil leakage on connection between exhaust manifold and exhaust pipe. Took it to the dealer for diagnosis which was blown head gasket. Received no detailed description as to why this happened or extent of other equipment damage. Head and valve gaskets were replaced. No mention of engine replacement or whether or not new gaskets are root cause fix or short term fix. Vehicle still under manufacturers original factory warranty. This component failure is unacceptable for late model/low mileage vehicle.

Engine cylinder in back of vehicle is leaking oil. Contacted dealer, and dealer is not willing to do anything. The oil leaks onto manifold and starter, strong odor of burning oil was present. The dealer stated that the oil leaks from the right hand head gasket at the rear of the block or head joint which was caused by a metal chip in which debris lodged between the head gasket and the block.

The contact owns a 1999 Ford F-150. The contact stated that the intake manifold gasket failed on the vehicle three times. In 2000, while driving 40 mph, the check engine light illuminated on the instrument panel and the vehicle began to stall. He noticed white smoke coming from the rear of the vehicle. The manufacturer was notified and informed the contact that he would be liable for the repairs. There were no recalls on the v8 engine, only the v6 engine model. In 2008, the manifold gasket failed once again. The vehicle has not been repaired. The failure mileage was 37,000 and current mileage was 86,000.

When driving at any speed and applying the brakes, abs system kicks in which causes the vehicle to skid. Also, both sides of the exhaust manifold engine bolts are loose, and there is a leakage which causes fumes to enter vehicle.

Poor gas mileage; has averaged 15. 4 miles per gallon, and Ford advertises 16 city to 20 highway. Other f150 owners report poor gas mileage. Is this false advertising because I would never have purchased truck getting 15. 4 miles per gallon when I travel mostly highway miles. I have a loud rattle noise under truck and the catalytic converters and muffler have all been replaced! also, vibration via gas pedal from engine (?) noted between 45 and 55 mph.

The head gaskets with 4. 6 and 5. 4 engines were defective. (Ford bulletin 02-22-07) the oil dripped onto the flange which held the exhaust pipe to the manifold on the right side of the engine. Scc.

Engine head gasket blew out, causing coolant to leak onto manifold and engine. Dealer has been notified.
