FYI, Toyota's 4.0 V6 makes this noise too. And I put 50k on my FJ with no problems whatsoever. I also had an '05 Tacoma with the same engine and same sound and it went to 80k with no problems before it was sold.

I don't see how this is an issue, rather than just an annoyance for some.

 

All vehicles, whether domestic or foreign, will have some issues. It all depends on what you like. So saying you are going to go foreign because of a few problems, is not an end to your problems.

If you can hear the engine, the exhaust isn't loud enough!

 

WOOOHOOO!!!!! After repeatedly being misdiagnosed by the dealer, they are finally going to replace the cam phaser on my 4.6L 3V. I've been through a new a/c compressor, pulleys, pcv valve, and reprogramming the computers. I was beginning to think the knocking noise was normal and I was just going crazy. I will be picking my truck up next week and hopefully it solves the problem. It was driving me insane. I only have 8k miles on it, so if this isn't the fix, it's going right back into the shop, and I will be shouting "LEMON LAW"!!!

 

The modular motors have pretty loud injectors too... Not really anything you can do about them, but you can sometimes hear a "tick" at idle from them, though it's not loud at all and definately doesn't sound like a diesel.

 

Had my truck into the dealer today to check the check engine light being on. They have ordered a VCT Solenoid and a cover gasket for it. I haven't had any abnormal engine noise outside of the noisy injectors that are loud no matter if it's hot or cold. Anyone ever had this done or know anything more about it? Thanks in sdvance.

 

I wonder if my 2010 has this issue... Mine has 17k and today I heard the loud tapping knocking noise going through parking lots at 10-20mph. It was louder than normal... I guess I will be headed to the dealer.

 

Well, only did it at idle and full temp. As soon as you would touch the gas pedal, it was gone. I have heard of injectors making noise, and sounds more like what you have an issue with.

 

Same here with a 2010 4.6 3v. Did you ever get this issue resolved? I swear my truck sounds like a diesel at idle. Only 9k on the odo. I have heard other 4.6 3v and they all sound the same. Widespread problem or just normal. Can anyone point me to a video with a good example of what this sounds like?

 

I posted this in another thread, it should help determine what the noise is:

---
Almost always it's the injectors, very common compliant, unless the phaser (VCT) is broken.

Take a look at episode 22 of the following link to help with understanding noise from the engine. They have samples of the common emitters.

Thanks, that was a really good video! The noise I have is just the injectors and is normal. This was exactly what I was looking for. I have been told this noise was normal but this is great confirmation. Though the dealership might be blowing me off.

FYI, if anyone is having an issue playing the video download SMplayer

then paste in the mms:// link to the video you want to watch.

 

I have the same issue 2004 F150 5.4 78k I have been driving with that tick,tap,,for the last 35k.I can t stand it.Every dealer has some thing different to say about.It's an on going issue for the past 7or 8 years at least..Ford should at least step up to the plate and split the cost with the vehicle owner. They told me it was a Phaser(fancy word for cam sproket),also a lasher(lifter). I'll just drive it till it blows..with my luck I'll hear that tick,tap for another 100k..???

 

Trust me, a dealership isn't going to blow off a chance to work on a vehicle. There are some noises that are just normal with the operation of an overhead cam engine, even overhead valve engines for that matter. Being a parts guy at a ford dealer, i can only speak for the dealer i work for, but no matter what the issue is our techs go through all the proper pinpoint tests, and there are times where we can not replicate the issue at the dealership, so the only thing we can do is give the vehicle back to the customer and tell them if it does it again then bring it back. The only way we can resolve issues on new vehicles is through the pinpoint tests. For instance we sold a new 2011 6.7 SD. Transmission had an issue and we couldn't replicate it. Because the customer was patient and kept with it, we reflashed and then contacted Ford engineers, because the issue hadn't been seen in other 6.7s yet, Ford sent a team of engineers down to tear down the transmission, they then made a phone call and said we need a new transmission assy. diverted from the assembly line and sent to this dealership. If the new truck is under warranty, i know the inconvenience of time down is a hassle but I can assure you that most dealers try to resolve the issue with the resources they have, even though sometimes it may not be the desired answer. That same customer is now happy as can be and hasn't had any problems with his new truck since.

 

Here i thought i was going crazy hearing exhaust in the mcdonalds line???? Does anyone have any experience fighting with FORD regarding this issue within 1k of being over their warranty cause im assuming FORD is going to say "sorry about your luck" and claim lack of maint or excessive abuse. I have loved all my ford trucks but this 09' i have hated it since i drove it off the lot. Sounds like chit.

 

I am looking for anyone who can share a similar experience regarding their Ford truck and service from Ford Canada.

I recently purchased a second hand, 2009 Ford F-150 XLT Super Crew truck, with 80,000km through a PRIVATE sale. The truck was inspected and seemed to be in great shape. I had the truck for about 3 weeks before I started noticing a noise from the engine when it was under low idle. The truck was taken to Ford in Lethbridge, Alberta where the camshaft phaser was replaced under the 100,000 km power-train warranty. I got the truck back and one day later the problem returned and seemed worse. Under low idle the engine sounded like a diesel. The truck was taken back to Ford and I found out a week later the camshaft was damaged and the problem was attributed to low oil pressure. The cause I was told was from engine sludge which could have been caused from lack of maintenance. Ford asked for the servicing records which I could not produce being the second owner and the original owner was in the process of moving to another Province and could not locate them. The previous owner assured me the changes were done at various drive-thru oil change locations in Canada and the United States as the truck had been used for some business and vacation trips.

Ford Canada reviewed the pictures taken by Ford and said without the proof of oil changes wrote the file off as lack of maintenance. The service manager I spoke with told me even if I was able to find the service records the engine might not be covered by the warranty as the type of oil and filters could be an issue. My response to this comment was Ford Canada was no doubt doing whatever they could to avoid covering the engine. The response I received was "Yes you are probably right."

I have since forwarded the same pictures to other mechanics (including a Ford Mechanic) and have been told the pictures do not indicate the engine was poorly maintained nor was it believed the deposits lead to engine failure. I have researched the same issue on the internet and have found others who have had similar engine failure with the Ford engine... which is a oil pump and phaser malfunction can lead to low oil pressure engine damage. I have been in touch with a former owner of a Ford dealership who has told me "Ford has had oil pressure problems with these engines for a long time and THEY KNOW IT."

I attempted to contact Ford Canada and did not get past the person who answered the 1 800 number. The employee would only say Ford Canada stands behind their decision to not cover the repairs under warranty. A second phone call to the 1 800 number resulted in the call taker saying the same thing and finally telling me they had been instructed to end this phone call. Now Ford Canada will charge me FULL RETAIL for an engine at $9000. There has been no attempt by Ford to negotiate on a price and I do believe a fair decision could be reached. So far two friends who have been looking for trucks have chosen GM as they feel the same.

I have pictures of the camshaft, valves and cover used by Ford to say the engine was damaged from sludge. You can clearly see the oil chambers and ports leading into the valve and camshaft are clear from debris and sludge. I will be filing a complaint through legal arbitration and I am looking for anyone who can give me any advice to help in my fight which is far from over.... In particular anyone who has had , or knows anyone who had had similar problems with the F-150 engine.
