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.

I have a 2011 f 150 that has been in the shop 3 times 3weeks at the time and can tell you this truck was pushed on me as being better than the v8 , nothing but problems . the twitter for ford guy i tweeted and @FTC was @kenatcman. Any one having this problem or attorney interested should get a class action lawsuit started. 2009-2011 vehicles are having this problem with v6 twin turbo

Funny there is no such thing as a 2009 or 2010 V6 turbo.

My recommendation is that dual variable overhead cam engines should be worked on by qualified persons. It is not cut and dry, and it is not just lining timing marks. Trust me, I get many calls.
Not saying don’t do the work yourself, but make sure you can take this job on and worse afford the new motor should it be wrong.
There are changes right now to primary tensioner and some parts. From our testing and development the newest tensioner and some components that are the new updated parts are not the best ones to use.

I realize this an an old post but I'm working my way through it. I have 2 Blackstone reports from my engine from 2 of the 3 oil changes since I've owned it. I can PM you or anybody their results and comments, or post here if wanted.

I'm only to page 46 yet, but it appears some last 60k+ miles after they first hear it, and some went 200 miles between first noise and failure. My engine had intermittent phaser noise on startup when i bought it, and worked fine for over 12k miles, but now I believe I'm busted.

I have let mine go for approx 10k miles before it threw a code. I also didn’t catch it at first, because I didn’t know what that noise was.

The timing phaser clacking and a stretched chain are generally two different things and should not be treated as one.
1-When the variable cam timing in degrees intake bank1 rolls aft (positive) +6 degrees you will throw a check engine light indicating a stretched chain.
2-I am not saying not the have the phaser clacking issue addressed but if you are able to watch your
variable cam timing as mentioned you ***can*** generally know where you stand.
3-Oil analysis will be important in my opinion to monitor wear. The phasers clacking on cold start is a result of phaser bleeding down or draining back which it is not suppose to do.
4- If you want to help your situation regarding the cold start noise. (let’s say you don’t have the money and are in a tight spot) and you literally cannot fix the truck do to those type of circumstances)
Put your foot to the floor turn the key until the oil pressure builds then let off the peddle and start the truck. Oil pressure will build filling what has drained back or bled down. It isn’t a permanent fix and should not be treated as such. However it will prevent that cold start clacking noise which will prevent accelerated wear in the phasers. It will do nothing with any accelerated stretching of the chain.
If you do notice your variable cam timing intake bank 1 rolling to + 6 degrees or more, you should have it fixed because letting it go, it will eventually stretch past what is acceptable and you will bend a valve or have other issues.

Same exact parts except for one minor guide which has no impact on the issue. Further I’m sure the 3.7l have the same problems. They are no different other than some cam timing, but VCT or cam movement is identical.
The oil type isn’t a cause of the issue, and the issues have been confirmed.
Separate topic:
If oil is being diluted to a 5w20 whom ever is running their oil to get that thin is not running good oil or it is too long of a service interval. Further, a tune can be far to rich, (very common) and diluting the oil prematurely. Blow bye, too much crankcase pressure will cause quicker fuel dilution as well due to improper ring seal and piston ring flutter from too much pressure across the ring backs.

Just picked truck up from Ford shop. Had latest tsb concerning timing chain (16-0027) done.
$2400! Timing chain guides were not in the tsb but had them replaced. Also new belts, since no extra labor was involved and new plugs and boots, which I was going to do but, mechanic said he'd throw them on.
Cold start rattle started months ago, but didn't throw code til last week, so figured I better get taken care of. Had approx 85000 miles on truck when it started. This is a known issue and Ford should be taking care of it up to 100,000. Even called customer care, told them been driving Ford pick ups for 30 years, have maintenance records, how 'bout a little help....nothing!
Anyways, parts and labor are covered for 2 years, so there's that as consilation.
Anyways, thought I'd share and will post on any issues after this repair!
