My motor had started ticking a bit back in September 2018 I added some oil and it went away. Then, in January 2019 I had engine codes. Plugged my scan tool in and said I needed both camshaft sensors, misfire on cylinders 1, 3, & 7. replaced all 8 plugs and coils, motor had 123xxx miles. Drove another 4000 miles and the same problems persisted and got worse. I took it to a mechanic for a diagnosis on the misfires and engine tick, come to find out it is a 'lifter tap', shavings of aluminum in my oil and plugging up the lifters. Mechanic said to get a new motor, don't both trying to fix it. I bought it used with 119xxx and truck ran fine in August of 2018.

Plastic timing guides are ripped from mounting location by timing chains and drop into the oil system, usually causing loss of oil pressure, contaminated oil, trash-filled motor, and accelerated wear of the timing chains, resulting in engine damage. Usually the guides break off at or before 100,000 miles and the chains need replacing between 120,000 and 200,000 miles, depending on how the truck is driven. Metal replacement guides are available at most shops and online parts stores.prices range between $10 and $40. Occurs in 4.6L and 5.4L V8 engines.

The engine 5.4 Triton makes a sound that resembles a diesel and sounds like the piston is about ready to come through the block. I first experienced this approx. 3 years ago while at a drive through fast food restaurant. I immediately turned off the engine. I then restarted and the noise had stopped. The motor now still has the same issue, and after reading many forums stating the same conditions, decided to call Ford directly. The response from Ford was they know about the issue on these types of motors, but are not issuing a recall for the fix. The issue is apparently related to a know cam, timing chain issue that has to have the gears and timing chain replaced. At the owners expense of approx. 800-1200M dollars per side on this type of V8 motor. I recommend that Ford needs to do a recall on these, and fix the known issue, thus creating further purchases from consumers for future purchases of their product. If you are in doubt of this issue, just type in your search engine, 2008 Ford F150 loud knocking noise while idling, and sit back and read until you are tired of reading. Please feel free to contact me with any questions. Thank you.

When the brake is depressed the engine accelerates (never know when this is going to happen). I have had three instances over the total 8 years (first owner). All three times the brakes are ineffective in stopping the vehicle. Two times backing out of my driveway (afraid that the truck would cross over my road and hit neighbor's vehicles or home. Once it occurred at a all stop intersection. In most cases I had to take the truck out of drive to stop it. I'm afraid it is going to cause serious issue with life and property. There are nine other reported cases of this happening on 2008 F-150 vehicles see website for the nine reported cases ( M.carcomplaints.com/Ford/F-150/2008/engine/unintended_acceleration.shtml). I think there is an issue with the throttle body sticking but have no idea. I checked Ford and there is no known recall for this issue. So far no injuries or destruction of property has occurred with me but some of the nine other cases has occurred. Would greatly appreciate your help so there are no fatalities regarding this issue.

When the truck is under 1000rpm and at normal operating temperature, it begins to knock like a diesel and shake violently. This is only remedied by turning the truck off or reving the engine over 2000 RPM. The check engin light never comes on and at all other times the truck drives normally. This had begun to happen more frequently, including at red lights, my truck has only 78,000 miles

This is only remedied by turning the truck off or reving the engine over 2000 RPM. The check engin light never comes on and at all other times the truck drives normally. This had begun to happen more frequently, including at red lights, posing a danger to anyone driving the truck. Diagnosis has taken three mechanics including a Ford dealership who is still not 100% certain the issue since there is no check engin light or other issues.
