Ok so some may know about this some may not but it is something that is coming on strong with many showings at dealerships across America. So as most know it is timing chains that are prematurely stretching causing this startup noise. The news is that there is updated parts out there to address this and Ford now has a TSB on this issue formally admitting to it being a common problem. I go over it all in this video. There is also a link to just how it sounds in the description of the video on youtube. Hopefully more dealers will be willing to dive into the engine with some guidance from Ford now.

Hey travr6
What brand oil do you use mostly on your truck?
How often do you change your motor oil?
Brand of oil filter?
Any hop ups on the truck?

Oil has nothing to do with it nor does the brand or filter used. It happens regardless.

This is true. What does play a factor is what your OCI's are. 5000 miles max is a good rule to live by unless you do oil analysis often.

My OCI's have always been 5K miles/8K Km's. Still happened.

The ford tech at my local dealership (this is a guy that actually wrenches on these trucks) said the OCI suggested by the computer are complete BS and that if you want the motor to live to go back to 3000 miles between oil changes. He also said if my truck was still under warranty he would just replace the whole motor, to much of a risk on his part to do the chain and then have the truck come back with the same problem.
How can say the oil and filter have no effect? Are you saying all oil is equal? If that is true how are some of these trucks getting to 175,000 miles and some only getting to 60,000 miles? I believe its based on the OCI and the quality of oil used by the owners.
I clearly had broken down oil deposits clogging my VVT solenoids. (pictures to follow after this weekend)

3k? Sheesh!
I've been banking on 5k being appropriate.
I'll never believe the oil life monitor can be trusted on these. The OLM is to get the truck through warranty, imo. Then it's yours to worry with.

Mine had synthetic oil from the get go. 5k mile oil changes. Ford filters. Still had phaser failure by 60k km.
It has been said the phasers have been plugged with casting or machining debris from day 1 which slowly plugs that passage ways to the phasers starving them on start up.

Just asking more out of curiosity, but it seems most of the folks who have had this problem also live in parts of the Northern US and Canada. Does the climate play a role since this becomes a problem at startup after sitting a long time? My Tremor gets parked in my garage overnight, so even during our rare freezes in DFW (like the couple 15 degree nights we had in Dec) my garage is still near 50 degrees. So, I rarely start my truck after sitting 8+ hours in sub-freezing temps, therefore my oil isn't quite as thick at startup.

Here are the technical properties of amsoil signature series and different grades of this particular oil. Based on this, I would think it would need to be very very cold to have an affect.
I'm having the timing chains replaced at the dealer as I type this. Had all of the codes addressing the issue pop up last week. Prior to that it hadn't been running right for about a year and I'd taken it back to the dealer 4 times. I'd feel a slight miss when accelerating hard and it wasn't as strong. When the codes came on I took it to the mechanic around the corner who let me know what it was and said he'd fixed 3 others in the past year. He wanted $4700. I declined and took it to the dealer without letting them know of the previous assessment. They came up with the same conclusion except they wanted $2700. Warranty is 2 years/unlimited mileage.
What' clear is it's not a lubrication issue. I've had a number of used oil analysis done and they've all been very good. The truck has 156,000 miles on it and doesn't burn any oil at all. It's a structural issue with the chain. Ford obviously recognized such in 2014 when they beefed up the chains.
Now to get them to help out on this....

I guess it's a good thing my trucks been stuck at the dealer for two weeks with this issue then if things have been just updated....
I'm at the point where I wish they'd just replace the entire engine or buy my truck back and give me a new one.
I wouldn't exactly call it normal wear and tear. A high mileage truck like that probably has low operating hours and a high speed average. I wouldn't be happy in the OP's shoes, particularly when Ford's own torture test videos six years ago showed almost no perceptible timing chain wear.
He's not gonna get a dime from Ford being that far out of warranty though.

I just got mine back yesterday from having the TSB done. 2014 with 51,200 miles. The service advisor was great. They had my truck just shy of 4 weeks though. My truck sat overnight after bringing it home. After sitting about 24 hours I cranked it up and heard a similar noise to the chain rattling, but not as loud. It was faint and not as high pitched. Is it possible replacing all the parts didn't work? Or is there something else on these motors that makes a similar sound? I was thinking vacuum pump, but I'm not sure. I have full confidence that the dealer replaced everything like the receipt says.
I'm completely new to the Ecoboost motors.

Maybe it's just me but I don't see anything phaser related, just chain.
Correct me if im wrong, I thought the newest replacement was chain, phasers and all parts related or the noise comes up if just chain replaced.

I kind of noticed that too after I got home. When the guy called and said they heard the noise he said that all the phasers would be replaced too. I'll know in a week or 2 if it's still rattling.

After comparing TSB 16-0027 with my receipt, part number for part number, they replaced everything listed on the TSB.
