Filed Dec 26, 2019 · Electrical, Engine · 127,940 miles · VT

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.

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 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

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, 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.

My 16 year old son was driving our truck and the engine started to knock and then proceeded to die. It started back up but it will die when you start to slow down for an intersection or to park. Our truck is only 5 years old, only has 121,000 miles, and has had its oil changes regularly. There is no reason we should be having a problem like this with the truck. When I talked to our local auto mechanic he informed me that he has replaced the cam phasers in 7 f-150's in the past month. This seems to be a problem that should be looked at by ford. The repair is not cheap and I believe ford has a responsibility to look into this considering the danger of the vehicle dying whenever it wants with no warning. I thought I was giving my son a reliable truck to drive but as it turns out he cannot drive it because I feel it is to dangerous for him with the engine dying.

This weekend we heard a loud pop under the hood followed by a loud ticking sound while driving on the freeway. We pulled over and waited for a tow truck to take our car to the dealership where it was examined today. We learned that this common issue in ford f150 trucks will cost approximately $1000 (low end) to $3500 (high end) to fix. A spark plug simply "popped out", tearing up the threads in the cylinder, causing the dealer to recommend cylinder head replacement. There is something else that can be a less expensive fix to the problem, but ford does not guarantee that fix. My vehicle is 3 years old and has 70k miles on it. We are very meticulous about the maintenance on our vehicle and as the dealership explained, this is a defect in this engine design and not something that we could have done to prevent the problem. They recommend a tune up to replace all spark plugs because of this issue. My warranty has expired and I do not have an extended warranty. After driving my last ford f150 for 200k miles with no issues, I have a difficult time paying $4,000 when it is all said and done on a vehicle that I am still making payments on that is only 3 years old.
