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.

Sounds like a rod knock on startup but quiets after idle down. what gives and can this be a big problem? 75000 mi.
View 2 RepliesSo after a decent drive when I get to a redlight / stop sign / etc the truck will idle rough and shake but giving it a little bit of gas (1k RPM) seems to smooth it out however it doesn't throw any codes or the CEL. The truck is a 2008 F150 with the 5.4 and 90k miles.
I've searched quite a bit on this issue and I can't seem to find any real fixes other than swap parts out until something works and I've heard everything from filters to cam phasers or low oil pressure (I will be taking it to the mechanic to check the oil pressure)
so far I've:
Replaced the air and fuel filters
Changed the oil and oil filter (synthetic and OEM filter)
cleaned the MAF and cleaned the throttle body
also is 2008 equipped with an IAC Valve because I've read that it wasn't and I can't seem to find the IAC if it is.
Getting these codes what they mean or need to do ..to get rid of them...p0022, p0171, p0174, p0183, p0340, p0300, p0316, p2006 did timing n plugs fuel filter n gas filter getting very bad gas mileage it runs good but here a ticking in motor at idle and more as u accelerate, running rough....
View 7 RepliesI 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!
View 3 RepliesI 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.
View 3 Replies5.4. 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:
2004 f150 cold start knocking noise - YouTube ....
Need to verify what this is??? Some people are saying cam phasers and some are saying I'll need a brand new engine!
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.
View 2 RepliesMy car is making this noise. Its only at idle. Doesn't affect fuel economy, just alarming.
View 19 RepliesHaving 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.
I have a 2004 ford f150 5.4l v8 triton lariat and while at idle it has a ticking noise like this video
YouTube...
However I also have a rattling noise when decelerating at around 2000 rpms that sounds like a loose chain in a box. Not sure if its VCT sensor or cam phasers ...
I've got an 06 F150 5.4, and its making some noise. It has a constant tapping noise that can be more easily heard when I'm attempting to order my fries at the drive thru. The issue is, I'm having some difficulty identifying it. The tapping noise is very noticeable at idle, and becomes sickeningly loud at approximately 1000 rpm (in neutral) and almost disappears after 1200 rpm. i know for sure that it is not the normal noisy injectors, and it sounds too distinct to be a lash adjuster or lifter. I have not been around a truck with bad cam phasers to know what it sounds like. I don't want to start throwing parts at it until i know where to look.
View 14 RepliesI just got done with 2007 5.4 Triton with cam phaser noise. I replaced phaser, timing chains ,tensioner, oil pump, and it still made noise at idle when it was hot so a change the oil to 0w40 and my noise went away. 5w20 starts to brake down at temp of 180 but 0w40 works up to 212 ford will tell you all you need is 25psi of oil pressure what I have seen is you need at least 40psi of oil pressure so if you have noise try 0w40 mobil1....
View 2 RepliesI 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?
View 3 Replies have been lurking the forum for the last several months ever since I bought my 2008 F150. I bought it used from a dealership and have had it at their shop no less than seven times since I bought it in March, all for the same things.
The first thing I noticed shortly after buying the truck was that after the truck warmed up it would idle rough. My chief complaint by far, I took the truck in to be looked at and this is when all the real fun began. Similarly I had intermittent power steering that I asked to have looked at.
I was told the fuel filter was completely clogged. They cleaned it and assured me all was well. They also bled the power steering system because apparently someone had changed the PS pump and not bled the system afterwards. I got into the truck to leave and it was idling no better than when I dropped it off. I complained again and was told that "this is just how this truck idles" and called BS. They offered to have the throttle body cleaned for me the next day to alleviate any remnants of rough idle.
Had the throttle body cleaned the next day and took the truck home. After about an hour or two I was still thoroughly dissatisfied with the idle and called back to complain. I forgot to mention that I bought my truck from a Chevrolet dealer who had just taken it in on trade about three days before I bought it. Because I complained they offered to send the truck to a Ford dealership for further diagnosis.
The Ford dealership found fouled plugs, a cracked intake manifold and the water pump and fan clutch both had excessive play. They said those would create a rocking sensation which could be misinterpreted as a rough idle. Over $2500 the Chevy dealership paid them and I was called to come pick up the truck.
I didn't even make it out of the parking lot because the truck was whining something fierce. I couldn't believe no one QC'd the vehicle and complained again. Next morning I am called and they said that the Ford dealership had put the intake manifold gasket in wrong and it had been corrected and I could come pick up the truck.
I go pick up the truck and note that not only is the idle still not right, but now the truck is making a hissing/squealing noise when the truck hits 1800/1900 RPM's. Its strange because its not really RPM specific as it is specific to the pedal position. Accelerating or decelerating causes it to go away but its there nonetheless. Whats worse is that in highway driving at 65 MPH, the pedal is in just the wrong position and it hisses constantly. This sound never goes away...and once its been heard its impossible to unhear.
I complain again and they send the truck back to the Ford dealership. At this point I'm dealing directly with the Director of Service because mine has become a high priority case. The Service Director drives with me, confirms my problem and takes the truck himself to Ford. He drives with their shop foreman and they too confirm the problem.
A week goes by and Ford tells him its wind noise. This is complete bullarky because it happens whether I'm going 20 or 65. He calls them on it and they keep the truck another couple days. They call back and say the truck has nothing mechanically wrong with it and that they are done. Service Director goes and picks up the truck and takes it to a second Ford dealership.
Three days go by and they call and claim Eureka! We've found the problem! Clogged catalytic converter causing air flow restrictions. They replace two converters and I go to pick up the truck. It runs like garbage. Further the sound is still there. Call Chevy, leave the truck and take their loaner back home. Next morning Ford's Foreman calls and basically tells me that there's nothing else wrong with my truck and that he even reprogrammed the PCM (which is why it runs to bad all the time now I guess) to get rid of the idle problems.
Long story short here's everything thats been done:
- Cleaned a clogged fuel filter
- Replaced fouled plugs
- Replaced the intake manifold and gaskets
- Replaced the fan belt
- Replaced the fan clutch
- Replaced the water pump
- Replaced two catalytic converters
- Cleaned the throttle body
- Bled the PS system
- Reprogrammed the PCM and transmission control module
After all of this I still have a hissing sound when I accelerate (video 1:
It seems the truck runs worse once its warmed up and even worse once the AC is turned on. I'm sure he programmed the PCM wrong and thats what is causing the truck to run rough.
I recently got Gibson Performance Headers on my 2006 Ford F150. And when you cold start it or just start it period it has a odd ticking noise on the passenger side.
View 3 RepliesNoise goes away (or maybe it quietens to the point that you can't hear it) when you raise the idle just slightly. No smoking, no hard to start, no rough idle, no indicators of anything wrong at city or highway speed, nothing else out of the ordinary to report.

I have a 2004 F150 Lariat Supercrew 4x4 . I got a new transmission put in and a Oil change shortly after. A few weeks later I got a knocking noise. No check engine light, starts up great, No real notable problems just the noise. At Idle no noise just the usual cam phaser ticking, but once the engine is warmed up at about 1100 RPM it starts knocking like a . I took it to a few different shops one was sure it was the timing area so they replaced the timing chain, tensioner, pully. ect. Took it to a ford dealer where he didn't really look at it just said you need a new engine.
I went to another ford dealer where they said rod knock or stuck lifter but if that were the case shouldn't it knock constantly? another shop said VCT soleinods, Spark plugs. another said it could be the flex plate! I'm aware of the cam phaser diesel ticking noise they notoriously have but thats not it. I've parked it for a few years to be safe but started it weekly. I didn't intend on having it sit for so long but due to work situations and what not it has sat but now I'm on a mission to make it my daily driver again. I'm no mechanic but I'm not totally green to vehicle mechanics so ill be inspecting what i can within my limits.

I have an 05 f150 5.4 v8 super crew cab and I bought it for 3000 because of a cracked block. I bought a re-manufactured engine and installed it and now i have a knocking that wont go away. After I started it up it sounded beautiful for about 10 minutes and then i had a knocking start up. I have put about 30 miles on the new engine and still have the knocking. I let it sit over night and I started it up and there was no knocking so i drove about 3 miles to the gas station and by the time I got there the knocking was back. it runs fine no other issues but why do I have this knocking with a new engine.
View 9 RepliesI have a 2004 F150 with a 5.4L with a little over 100,000 miles. And the engine knocks like it about 1 1/2 quarts low on oil! I'm not a mechanic by any means, but I'd like to know how to get this fixed. I've actually had 2 different people ask how I got a diesel engine in a 1/2 ton truck!
