I just bought this truck yesterday. During the test drive and everything it seemed all fine. After all the paperwork and the truck was actually mine. I noticed once it is all warmed up it seems to have a slight knock/tick? and a slight miss to it. I shot a couple videos, one up underneath where it sounds like most of the noise is coming from. Could it be an exhaust leak? Or is it something internal? Like the Cam Phasers, or a rod or something!

It did however come with a 1 year unlimited mile warranty through warrantys.com, with only a $100 deductible


Here is the link to the ad online where I purchased it from.

Here is a video around the exhaust area.



Here is up underneath the truck.

Does that what the ticking sound is?

Hope it would be covered on the powertrain warranty!

Couldn't really get the video to play steady so I could hear the sound but I did click on the website that you bought it from. Did you notice that it said 5.4L 16 valve engine? The phasers are only on the 3V version (3 valves per cylinder, 24 valves in this engine). Probably just a typo but I do know that there were 2 versions of the 5.4 in that year, the 16 valve version (older model) and the 3 valve version. From the actual pic of the engine, it looks to be the 3 valve version (that does have the phasers).

Im almost certain to its the 3 Valve. I think ill give it a month or so and call the warranty company so I can probably get the claim denied.... Are there other things I could check that could be causing this? Would the phasers cause a slight miss in the engine, could spark plugs cause this, or Coils? It only seems to do this once its ran for a few minutes.

If it were me and the dealership did not provide any info concerning maintenance, I would probably do the plug change and maybe even the COPs to make sure. I would change the oil to motorcraft 5w20 and the motorcraft oil filter as well. Doing these things allows me to start my own service records that I refer back to when needed. Start reading the threads here on plug removal and make sure that you get the special tool, better to have and not use than to need it and not have it. I will try to listen to your videos again in the morning to see if I can actually watch them without the cutting in and out. By the way, good looking truck.

Thanks for the information thus far! I did some searching online, and I came upon another video that someone thought they had a manifold leak, come to find out they had loose spark plugs. The video almost sounds like mine. I can only hope. I plan to start with the easy and cheaper items first, then work from there.

Im just getting a bad feeling I got screwed on this truck! I wish I could of just taken it back. I have not checked anything out yet, I will.

Any tips on where to start?

spark plugs as hard as they are is probably the easiest. You can do seafoam in your intake (about a 1/3 of the bottle) through the brake booster hose and that will cause smoke to come out of the exhaust because it is cleaning internal parts and that will also let smoke out of a cracked exhaust manifold or show that it is not leaking. Youtube has videos on how to seafoam. If you unplug your VCT solenoids does the noise go away? Also if you rev to about 1200 rpms or above, does the noise go away?

Today I took apart the Throttle body to clean it, also used MAF cleaner on the MAF sensor. Still has a slight rough idle/tick at idle. I can bump the throttle and im not sure if the sound goes away or the engine noise covers it up. I did unplug the passenger side VCT and didn't get a change, just made it throw a code though. didn't do driver side yet.

I went and bought a motorcraft filter and motorcraft 5w20 and will change the oil soon. Truck runs good driving, its just a little rough at the stop lights, but has not stalled out.

I also noticed I always seem to have water drip from the muffler, looks like it has a few weep holes in it and water drips out of it. Not sure if its just in my head but the noise sounds louder from under the wheel well or underneath as opposed to the engine compartment.

I do have a stethoscope. Im not sure what I am suppose to be hearing though through it?
