So I know there’s a few people that have been dealing with this and I’m sure there’s gonna be quite a few more people that will.
Here’s a couple videos of my before repair and after repair for the wastegate rattle. At first they did the new VCT phasers that were just released on the 13th and of course that didn’t do much but surprisingly it did quiet down the start up rattle a little bit. Next they replaced both turbos and that did the trick. I have since put about 500 miles on the truck and all is still good. The engine is actually so damn quiet now when it’s idling it’s hard to tell it’s on from about 10 feet away, my gas mileage has gone up as well strangely enough and I’ve been getting on it just as much as before.
You can’t still ever so slightly hear them but it’s not even remotely close to what it was before, And not at all when blipping the throttle

For anyone that’s tired of your truck sound like a old beater when starting up in the morning or leaving from stop signs this should work.

Before repair cold start:



After repair cold start:



It’s weird actually being able to hear my turbos now and the exhaust very clear when taking off from stops

You don't know how happy I am FOR you.

Of all the inmates around here, you deserve a quieter truck.

@Sirikenewtron ; Sorry to dig up a relatively old thread. My truck unbeknownst to me has the same sound on cold startup as your before video. I thought it was normal. It goes away after 1-2 minutes and then doesn’t come back until next cold start.

Is this something to worry about in regards to longevity of the turbos/engine? What was the actual diagnosis? I don’t feel like playing the dealer/can not replicate/it’s normal game. Don’t even let them change my oil.

I don’t know about long-term problems but I would assume if something is loose enough after a while excessive vibration could cause an issue but of course I have no idea.

The diagnosis for this was extreme wastegate rattle, Basically I could grab the wastegate arm actuator and lightly shake it with my hand and it sounded like someone shaking up a can of spray paint.

On a sidenote though myself and four other friends with the second generation 3.5 ecoboost have, the only way I can describe it, a very very slight rattling on cold start that seems to end at perfectly one minute. One of those friends had his timing chain phasers replaced recently and it still does that as well as mine does and did before the timing chain phasers repair. The sound is not the same sound that I had my Turbos replaced for though, that sound is completely gone after the repair.

Interesting. I don’t know what to think. My truck makes what seems to be an identical noise as your “before” video. Only for a minute like you said, then it’s gone. While it’s doing it, I can put my hand on the wastegate actuator arm and quiet it down. Never do I hear it while I’m in the cab, or while decelerating.

I thought it was totally normal for these 2nd gens (My first gen never rattled). But seeing as they actually replaced your turbos makes me weary. I only have 12k miles so I have some time to see if it gets worse I suppose.

Yeah my 1st gen 3.5 and my 2017 2.7 never rattled either. This 19 was gnarly though

My truck does the exact same thing. 2018 3.5. It's getting dropped off at the dealer tomorrow. I'll post back with results as well. The service advisor told me over the phone that it's the timing chain without having seen or heard the truck, or being privy to my mechanical knowledge...I dislike dealers so much...

Put yourself in the service writers shoes though. Lol

7am-5pm. Line of unhappy customers standing in front of him/her. Hearing "I spent ____ number of $dollars on this truck and this is bull%*&#!"

Or, "I've bought Fords all my life and this is the last......."

And after a while, you gotta admit there IS a pattern that emerges of what specific year/models present as common symptoms and issues.

I'm not excusing the typical (and frustrating) negative experience we might have with a dealership, but it's not a job that's likely to be a positive exchange between humans on a daily basis. Lol

Kinda reminds me of my youngest son's job. Rural county Sherrif Deputy. 911 calls at all hours of domestic violence, usually the same addresses over and over. Alcohol and drug induced insanity. Unhappy households in a constant state of drama. After a few years, the Deputy just starts to believe they already know the problem BEFORE they hear all the evidence. Much like the service writer, they might not be right, but it's human nature to jump to conclusions.

Sure, but that doesn’t excuse the dismissive attitude.

Dealer called me back today. Told me the truck needs cam phasers. I rolled my eyes and asked to speak to the tech, asked him to read the work order closely and pay attention to the turbos and forget the preconceived notion that all these engines need phasers. He called back a few hours later and told me he has turbos on the way. Was really pleased with him, he wasn’t dismissive at all and appreciated getting more information from me. I think this should be more the norm. I’ll post back when I get the truck either tomorrow or Monday.

Update. Got the truck back from the dealer today and it's quiet as a church mouse now on startup. Keep in mind it was making the exact same noise as newtron's truck, otherwise I'd post the before video. The tech decided to lift the cab and update the phasers as well, apparenlty the longblock the installed at 20000km didn't have the up to date parts. He also replaced the turbos.
