Knock at Idle?

There is a thread at the top section of this page with a complete run down of a engine tick condition but that noise is from the drivers side of the motor.

If you are having a noticeable tick or knock from the right side then I would say take it top the dealer and get them to diagnose it since it is still under warranty but don't let them get away with telling you it's a "normal" noise.

Well thanks for the responses. Almost immediately after i posting, i realized this was a usless post and a waste of everyones time. I just hate any experinces with a dealer in general. I was hoping this was a common "minor" issue other have experince to put my mind at peace. After going through the fight with the tealer over the ticking issue tsb, i did not want to go through it again.

Anyone recommend a good dealer in the Calgary area?

Thanks again gentleman.

A valve train tick will sound kinda like a sowing machine. A normal sound for this engine will have a very faint, quiet sowing machine noise; sorta like a sowing machine under water.

I've only heard detonation once in my life so it's hard to describe.

Something you should keep in mind is that with a manual transmission, a gear roll-oer noise will be normal. The best I can describe this noise is a muffled, faint washing machine "worble"/oscillation. Usually you can hear it more with the AC active. With the radio on, you probably wont hear this noise.

Hey guys,

So i have used the search function put all that seems to come up regarding knock is hard acceleration and tunning related. I am not running a tune nore am I accelerating when this "possible" issue occurs.

I have noticed over the past couple of weeks that I am getting a "suspected" knock at idle. I say suspected becuase I have never personally heard a knock in my life. Esseintially the noise is coming from my passenger side cylinder head when idling. The driver side does tick a minimal amout but the sound I am hearing is somewhere between a tick and a knock. Its not loud and I have never heard it under hard acceleration. I have been on youtube for quite a while but cant seem to find anything but severe knocking and pinging.

I am optimistic it is just a lifter sound but I cant confrim. The sound seems to be in time with the cams. Can lifter noise be described to me? I allways use Shell 91 octane. I did have the cylinder ticking tsb done back in Febuary-March but that was clearly a diffrent sound.

I realize its almost impossible to diagnos over the internet but if anyone has any advice or recomendations that would save me a trip to the dealer, I would really appricate it.

My car has been to the dealer far to many times as is.

Hey Cpt.Carnage,

My name is Deysha with Ford Customer Service in the US. I first recommend you make an appointment with your Ford dealer to get your vehicle diagnosed like the others mentioned. Then contact Ford of Canada at 1-800-565-3673, so they can assist you further. They will be able to escalate this for you and work with your dealer to get this issue resolved. If you need further assistance, please do not hesitate to pm me.

Hello again gentleman,

Saw my dealer last week after work. I did not have an appointment but i figured i could quickly get one of the techs to swing by and take a listen as my car was obviously making the noise i suspect at the time. Reluctantly, the service adviser was able to grab a spare tech. He came and took a quick look. After about five minutes of listening to the sound i clearly heard, he concluded it was an injector or purge solenoid noise. While i was somewhat re leaved to hear his diagnosis, i am not completely satisfied. I understand this is not a "actual diagnosis" but when i inquired about seriously having it looked at the advisor somewhat frustratingly insisted it would cost me an hour of labor time to be diagnosed if there was no actual problem "detected". I would like to have his diagnosis in writing in case their is a genuine problem but because there was no work order written up, there can be no actual documentation. To save my self a hundred ish dollars in a "official" diagnosis that could go nowhere. I one again appeal to my fellow trusted forum members to take a listen and find out if i am crazy or not. Here is a quick youtube video that i think clearly makes out the sound i am hearing. Driver side cylinder head sounds fine other then injectors but there is a distinct noise from the passenger side cylinder head.

Again I realize you gentleman are not trained techs nor can you really tell without hearing it in person but I hope i can at least get a better understanding without wasting my time and money a the stealer-ship.

Once again, any advice or recommendations would be much appreciated.

I don't understand why this is costing you a dime? Even if it's a Canadian dime.:hihi:

Hey bud, our Canadian dollar is currently worth more then yours down south at the moment. :hihi:

Anyway, took my car back to the dealer today. I got a AWSOME service adviser who spent a good 10 ish minutes with me. I was able to replicate the problem right in front of him and he immediately heard it. He figured it was most likely the TI VCT solenoid and claimed he had seen this in several different recent Ford vehicles, regardless he would have a "senior" tech look at it. I then went to work.

Roughly 2 and a half hours later he called me to let me know the shop foreman personally hard worked on it. The foreman had confidently decided it was the TI VCT solenoids making the "common" noise. I responded with some skepticism and he offered to personally show me how they determined this. I then headed back down the dealer and was presented with my car. The foreman started it up with noise present. He then disconnected the solenoids with assurance it would not cause any noticeable harm when at idle. As soon as he did the noise completely diapered. He plugged them it again and the noise reoccurred. Apparently this is a very prevalent problem with the 2010 f150s with the 5.4 3vs. I was then presented with a tsb for the f150 where ford clearly stated they would not warrenty noisy solenoids and there would be no noticeable damage or power lose.


They did not charge me a DIME, despite what a previous advisor had told me.

I know many of you are probably skeptical but this is the first time i have really believed what the dealer told me. I am not completely satisfied but i feel better. The big thing for me is that I have all my complaints documented in the event that it is a genuine problem and I can back up that I made mention of this issue and they disregarded it.

Thanks all for input and recommendations.

I haven't been here in quite some time, but I happened to find this by accident. My 2010 F150 5.4 3V has this exact issue, and is being repaired under warranty- not a dime out of my pocket- simply because the sound is driving me bananas. I talked quite frankly with the service writer and he said the same- won't cause any noticeable damage or power loss and isn't covered under warranty. When I asked him if it would make the difference between this being a 5 year truck and trade off, or a 20 year truck like it was intended- he decided maybe covering it under warranty was doable since I do like to buy my vehicles there

Sorry for the long story, I just had to interject...
