Ford F-150 (2004-2008) :: Very Loud Knocking Noise On Cold Start Up
Aug 25, 2013
5.4. So I have a 2004 F-150 that just passed 80,000 miles and a month ago it started making a very loud noise on startup, but only cold startup, meaning if I haven't used the truck in about three hours. Now I went on youtube to research and found a video of a truck making the exact same noise! Here is the link:

Need to verify what this is??? Some people are saying cam phasers and some are saying I'll need a brand new engine!

There's a thread similar to this on the front page, but I wouldn't exactly describe my issue as a "rattle".
I've got a good video of the sound it's making here : [URL] .....
It's definitely much louder with the hood up--doesn't seem quite as drastic when sitting in the driver's seat.
I've come across the thread here on the engine rattle/knock fix, but I'm not sure if this is the same thing. Would this be considered a knock?
It's a 2011 Elantra with about 82,000 miles on the odometer. It has an extended warranty on it, in addition to the 100,000 mile powertrain warranty on it, so it's at the dealership this morning.

We have had a few mornings (in garage) where it would seem to not really id say a knock but maybe a clicking sound and it would quit right away. This morning that did not happen so i shut the car off and checked oil it was low.
Got under the car and can not see any leaking no oil on ground. So i had a QT i put in and that seems to quiet it after a few seconds.
I called local TOY dealer and they said its common for 2010 to use some oil and not much they can do. I thought what is a little it was at the end of the dipstick.
They said they can only fill it up and then have me come back in 1400 miles and see how much is used.

My 2009 Sonata 2.4l Sonata has been making a loud knocking noise when it is cold, but it will fade to almost nothing after it warms up. I tried to make a sound clip of the noise, but it was so distorted that I could not even make out the noise on the video.
For some strange reason the noise matches the skipping problem I have been complaining about since the beginning. Yea it's still there. It sounds like it is in the valve system, not the lower end. It leads me to believe it's coming from the valve clearance/ camshaft area.

Truck-2005 F-150 XLT 5.4L ... Problem - Currently when my truck reaches a speed of 45mph+ there is a methodical knocking sound that comes from the passenger side dash. This sound is on the interior and comes from the far right corner of the dashboard.(almost as if someone is tapping with there finger every other second). There is no correlation with anything else being turned on or off that affects this sound.(i.e. air) It simply happens once I reach a certain speed and is not an outside noise. When I slow back down under 45 mph the knocking subsides.

I have an '05 FX4 with 5.4 and 55,000 miles. I've noticed that once in awhile when starting the truck after it has sat for at least a day I get a type of growling noise that lasts for a second or two. It usually happens shortly after the engine starts up and gets running, but it has also happened after it has run for a minute or two and then makes the noise when I give it some gas to take off. From inside the cab the sound seems like it is coming from the driverside firewall area, but on the rare occasion that I'm able to start the truck and jump out before it makes the sound it sounds like it is coming from underneath the center of the truck. It doesn't make the sound every time on a cold start and never makes it on subsequent starts. I drive truck during the week only drive my Ford on weekends and sometimes it goes longer without being started, but I don't know if this has anything to do with it.
I thought it was a shield vibrating or something but have also heard that the VCT parts can make a rattling sound on a cold start also and this has me a little worried. This sound seems more like a fast growl than a rattle, but it happens so fast it's over before I can really register what it is. One time it made the sound twice, once after startup and again after it had idled a minute or two, thats when it seemed like it came from under the center of the truck. The engine has had a slight cam phaser knock since new, but it is so quiet that it can only be heard if you're inside a building or next to a wall and roll the window down.
Also, I change the oil every 2500-3000miles and only use Motorcraft 5w20 and a 820S filter, and generally baby the truck. What this could be. The truck runs great all the time, I just get this noise occasionally after cold start.

When you turn the interior ac temperature from cool to warm there is a loud knocking noise coming from under the dash. I am new to working on explorers but it seem like its coming from the black box nearest the firewall above the transmission tunnel. When you turn it to cold the noise almost completely goes away. The noise gets even louder when you mess with the selector for "max ac" "head and feet" "feet" etc.

Ok, so my 2007 F150 Lariat super crew cab has been at the dealership for a week now with them claiming that a part is on back order. How hard is it for them to get in a right front axle?? Granted, it was in there for other stuff too (which they can not give me a straight answer on if they fixed or not cause they are claiming the technician hasn't done the write up on it yet). My main concern is that they are screwing me around or that something happened to my truck. I am planning on stopping by there on Wed. morning after I get out of work.
Are these trucks known for bad front axles or was there some kind of a big recall on them?
Other things it went in for was the radio having the CD's cycle through when you first start up the truck, but does not happen like that all the time. Black plastic driver side front door hinge is cracked exposing the metal reinforcing part. Whirring/bearing type noise when you first start up the truck when it is cold and sits overnight (which they claim they can't hear yet waited to bring the truck inside and check it out at 3PM when they had the truck overnight from the night before when I dropped it off.) and the front driveshaft not fully disengaging when the truck is in 2wd. Almost seems like the vacuum locking hubs are still engaged.

I have an '04 F150 with a P0430 code. Not sure where to start, I have read that it could be numerous things so I thought I should start knocking them off the list one at a time. Thought I would start with the cats. 2004 F150, 4x4, 5.4L, 126,000 miles ...

In this video I go over in detail the procedure to swap out the Cam Phaser to get rid of that annoying knocking noise at idle! It is easier than you think. The procedure is the same for all 4.6l and 5.4l 3valve engines.

I recently bought a 2007 Prius that is making a rather loud knocking noise that has me a bit perplexed. I know the noise is not normal as my 2005 does not do this.
The noise only happens when the ICE is running and the car is in drive
If the car is in park and you rev up the ICE the noise is not present. With that said I do not think the noise is isolated to something in the ICE as I think it would be present when revving the engine in park.
However is you put the car in drive and step on the brake (to keep the car stationary) while lightly revving the ICE the noise is present. The noise is present every time the car is in drive and you accelerating, even with the lightest of throttle.
It does not need to be under excessive load and with that said I am certain it is not spark knock/per-detonation of the fuel nor does it have the "pinging" sound like a spark knock.
If while driving down the road and the ICE shutdown down while driving at lower speeds the noise disappears. When the ICE starts back up the noise reappears.

I have an 04 F150 Lariat with the 5.4. I get alot of noise out of the top of the motor. I hear lots of stories of sludge issues, is that the problem or do I need to have the motor gone through? the knock is not horrible but when the motor is warm the noise is pretty apparent!

I have a 2007 F-150 4x4 5.4L. I recently had a problem with my engine. It had the knocking noise thats known for the 5.4. My issue is i replaced the engine (it had 275,000 miles and was a work truck before i bought it) As well as all the timing components including the hydraulic tensioners, new phasers, new guides, new solenoid, and a new camshaft positioning sensor and it still isnt fixed.

I have a 2006 f150 it was making a knocking noise after the engine oil temp reached 160* and made the noise to 1700rpms. I thought it was the cam phasers so I replaced them. The truck is still making the noise and running rough and stalling but not as bad and not as often. Before it did it all of the time. The truck is timed properly. I had a new cam sensor and tried it but that did not work. I watched vct on the scan tool and both cams are in sycn.

Loud engine grinding noise accelerating from stop when you first start the car? It is right after cold start, lasts 10-15 seconds until I get to 30-40mph. Engine sounds normal otherwise.

Having issue with his truck. He bought it 3 months ago and has no history. 166k. You now know as much as I do about the truck! He knows little about automobiles so fact finding has been difficult. I have done all my own work on countless US and foreign automobiles over the last 30 years and never take my vehicles anywhere. I will try to post as much detailed info as I can. I have read tons of posts now on various forums so I am up to speed on VCT and phasers.
This one seems similar, but not exactly the same symptoms which is why I am here. I have already pulled the VCTs and found the passenger side missing the top screen. I swapped them from side to side which made no difference. I checked ohms and they were at 15 which is normal from what I read. They were very clean and moved easily when I took them out so they were not gunked up so I don't think that's the problem. It idles very smoothly and isn't rough at all.
I have posted a video of the knocking/dieseling noise (link below) coming from the passenger side. The knocking starts as soon as the truck is started hot or cold (outside temps right now 70F-90F Houston). I can make the knock disappear by gently depressing the gas pedal going from idle of about 650/700 to maybe 750/800 and it will go away completely as long as I keep it gently depressed. As soon as I lift up it returns.
If I rev it up to 2000-3000 rpm it does not knock, however, as soon as I lift off quickly, it seems to knock at a high speed, hangs for a second and then knocks all the way back to idle. However, if I rev up and then lift off very slowly, it will not knock. I have tried to locate the exact location of the knock, but doesn't exactly seem right at the phaser, but actually back around the 2nd and 3rd spark plug area, but I can't tell exactly. I've had a couple people tell me the same when I asked them to tell me where its coming from. The noise is bouncing around in there so difficult to pinpoint exact area.

I wanted to get some second opinions on what this could be so I know where to go next.

2006 Sonata 3.3 V6 with 101,000 miles. At a cold start there is a loud whining noise coming from the engine on the passenger side. After the car warms up the whining goes away. The car has not had any noise before. It is progressively getting worse.

My 2013 Prius v made a really loud clicking noise this morning when starting the car from a cold start. It was less than 30 degrees Fahrenheit. The car has about 14K miles in it. Is this normal?

I have a 2005 F150 with the 5.4 in it and its getting ready to hit 90k here soon. I just bought the truck less than a month ago and Ive developed a very loud knock at idle. It sounds like it's coming from down in the oil pan. That's where I can hear it the best. When I give it gas and it reaches about 1400rpm it goes away to where I can't hear it. What would this be? I checked the oil level and its fine. I thought at first maybe it was just a heat shield from the cats loose and rattling but its gotten worse and louder. I'm not driving it until Monday when I take it back to the dealer because I still have some warranty left but I would like to know what I'm looking at maybe. This isn't the cam phasers is it? I've read somewhere that these motors don't get good oil pressure in the heads some places?
