Nope, stopped at a dealership in a smaller town on my way home to get the CEL read. Earliest appt available for them was also Tuesday. The CEL was in fact a misfire, but a different cylinder this time.

I'm thinking about getting an appointment with that dealership anyways. I talked to them about the noise issue on start-up which this thread is about and the mechanic pointed at another F-150 sitting outside the shop and said that it had the exact same problem as everybody else here. He said they replaced the timing chain and tensioner and it hasn't fixed the problem. The mech just wants to replace the whole motor in that truck but Ford hasn't authorized them to do so yet. I think I would feel more comfortable at the dealership since they are currently already dealing with a truck with the same issue, rather than possibly getting the run around by the dealership here in my town.

Hey just got a response back at 4:30 from my dealership saying ford Canada has informed them to not go any further at attempting to fix the problem's right now and that they were aware of the issue though and will notify them once a solution has been found. My service advisor and the shop foreman have said they are going to try one more thing, disconnecting the vvt module and see if it makes any difference before they give it back to me to impatiently wait for them to call with the fix if it ever gets on. I'll let you all know asap.

Are you tuned?

Very interesting, thanks for posting this. It seems to be a recurring issue for anyone who has had the repair and actually kept their truck.

With the amount of marketing and hype Ford put out over this truck/motor combo you'd think they'd stand behind the "minimal" amount of trucks with this issue (diagnosed and confirmed) and just slap a new motor in. That would send a pretty strong message to the consumer that Ford not only believes in this engine but stands behind it with their Ford Tough mantra.

It's a shame that your dealer kept your truck for 3 weeks to get that answer. They have been aware of the issue for months if not longer. They will happily drag this out until most guys are off warranty, then they will play "nice guy" when the truck finally caves and offer to pay half the repair. I went through the same BS with my wifes pontiac minivan and a blown transmission.

I am a sales manager, and have a good relationship with several of the experienced techs. We have not really had any complaints at our facility regarding the noise so when I heard the noise on mine a few times I googled it and saw the timing chain issue. So I went back to the shop duplicated the noise and they did not think it was timing chain because it is only at start up. We sent in a note to hotline and response was most likely vacuum pump, they were replacing a lot of them and they are on back order. My noise and symptoms were exact match to bad vacuum pump. Mine doesn't do it every time and is inconsistant, a timing chain issue should be somewhat consistent and I, along with other mechanics think that it should not only be for a few moments at start up with timing chain issue. I'm not saying it is not an issue or they are all vacuum pumps but I had myself convinced in 10 mins online researching that I had timing chain issues, when in actuality I did not. We have performed very few repairs on the ecoboost trucks at our facility, and if this was that big of an issue I feel like I would have seen several by now. Just my opinion.

Here Is The Vacuum Pump Noise:


Here Is The Timing Chain Noise We're Experiencing


Unless you have a hearing issue (no offense if you do) they are very different noises and several truck owners have already had Ford dealers confirm this issue.

I have not tuned my truck, the only thing I've done to it is put in some better speakers. I've been thinking about getting a tuner with a tow tune, but have yet to do that, I'm too afraid to pull anything until this all gets situated.

Mine makes the noise every single morning, some days are worse than others. Got a better recording this morning but the sound only lasted for about a second... there are some mornings it'll last for 3-5 seconds.

Here is my video from this morning though:


When I got my CEL read yesterday on the way home from work, they told me it was a misfiring cylinder, but a different one from last time. They reset the CEL and I drove home. Last night I changed my oil and oil filter, turned the truck on to make sure all was well, and it was. This morning when I started her up, I got that noise in the video and the CEL is back on. It seems as though the cylinder misfires in the morning when I fire up the engine. I'll stop after work again today to confirm it was the same cylinder as yesterday.

If it is misfiring they should 100% be changine the plug and coil on that cylinder. Don't let them eff you around by just resetting the code.

They can't get my truck in until Tuesday, I just stopped in to get the code read, and the plugs and coils are both consumables, so that'll come out of my pocket. I replaced all 6 plugs about 3,000 miles ago so it has to be the coils failing on me, and those things are what, $85 a pop? I would like to think that they wouldn't be failing at 51,000 miles

please know I'm not arguing just making a point that some people may be confusing the issues. Keep in mind one video is shot right over top of pump other is standing back from truck. Mine sounded just like second video, but mine also only lasted a second or two as well.
