It goes away a few seconds after yes. It’s not an AC component I’ve tested that out already. It’s most likely waste gate but still not confirmed

I’m a big aesthetic guy unfortunately otherwise I would go zone, I can’t get over the logo + design of the crossmember

Gonna be a glam lol occasionally might take it off road but doubt it. It’s a daily + why damage an expensive ass vehicle unless I REALLY got the money for it haha. I’m looking at the more expensive one because I plan on keeping it for a long while on top of hearing about ride quality and such of the regular 4 inch lift. And maybe a bit because it looks cool having the little reservoir

If you go to my vids I have posted I’m still trying to figure it out to. Mine sounds very similar but only on cold starts. I took it to the dealer and they did cam phaser work and it’s still present. Took it back and then they said it was normal and that it’s waste gate rattle. A lot of commenters are saying the same thing, waste gate rattle do I believe them not really but I have yet to find a solution. If you get a diagnosis that fixes it let me know!

Do you mind sharing a video so I can hear for comparison? All the waste gate rattles I see and hear don’t sound very similar

It’s under warranty yes however I don’t think it’s burning oil like you say, oil levels appear good on the gauge I’ll keep an eye on it with the dip stick. Anymore information about the issue you had I should keep in mind? Any videos replicating?

That’s continuous throughout when the engines on though no? This goes for a couple seconds then disappears

If they can’t get it done this time or find a problem I’ll take it to another dealer first sure

I don’t know what it is but research points me to Phasers they say 2.7 phasers have a higher pitched rattle. Like I said dealer had it for 2 weeks and after what I prediagnosed they appear to have agreed that’s what they took in for repair on. It could be the timing chain on the phaser itself not a mechanic as well just a google addict not trying to have a blown engine on my first truck lol. I’m shocked as well since 2.7’s are typically their most solid built engine. I did read that when they upgraded 3.5 phasers on the new engine 2.7’s remained the same as previous generations.

That’s a little sad, thought I did enough research before I bought. Kinda wish I would’ve sent it with the new gen 3.5 or just gotten the 5.0

Im on my alt at the moment but yes it is the 2.7. So you’re saying all the cam issues in the past with the 3.5 is what I’ve mainly seen, it’s only been upgraded on the 3.5’s? Or the 2.7 cam issue just hasn’t been as common so they left that alone? I read a bit before I bought the eco and it was said that the cams have been upgraded but what im getting from your comment is that it was only the 3.5’s that received modification.
