2.7L owners, what does your cold start sound like?

[MidwestRanger21]

Hey all, can’t find many videos (really at all) showing what the cold start from these engines sound like.
These engines are noisy and produce a lot of weird sounds, figured it’d be good to get a baseline of what they should sound like.

Whether mine sounds “healthy” or not, not sure. Partly why I’m starting this. I’m coming up to my 20K mile service, and I hear this distinctive rattle/ticking noise for a couple seconds that then goes away. I’ll see what the dealer says when I take it in, but it seems to only happen on cold start (sitting overnight), which leads me to believe it’s not a cam phaser. Let me know what you think though and feel free to post yours as well!

Here is a link to mine since video is too big to upload here I guess:

Noisy as shit, but nice and quiet once it settles into low idle. It can take some time settle down depending on how cold it is. Yours sounds normal to me.

Mine sounds like my F150 did when it had failing cam phasers (both times the cam phasers failed). 4500 miles on the 2025.

Rattly shit

Rattly shit

Pretty much the same as OP's.
And the 'rattly shit' is the HPFP (High Pressure Fuel Pump). Sounded the same on my '21 2.3L,

Wonder if we’ll start seeing cam phaser failures on these newer gen 2.7 engines…hope not but could happen.

I don't know when 'new gen 2.7' started, but you could check the F150 forums, see if there are any problems.

So it is indeed the cam phasers, but still on the normal side for noise. If it was louder and lasted longer, I would say get them taken care of. Having had the RR with the 3.0 and total failure at 900 miles, I know the sound. My 2.7 sounds the same. One thing I can suggest is go 100% synthetic oil. No blends, that will help short and long term.

I ended up finding a few more videos of F150s on a cold start with the 2.7L. Mine sounds pretty normal, just noisy. I’ve been diligent with oil changes at about every 4k miles. Though I did notice one time it was low (~5qt) when I emptied it for whatever reason? Shouldn’t have been enough to damage anything, I just do street driving. But I’m getting an oil analysis done next change just to be sure everything is A-ok.

IMO, a little rattle for a few seconds on cold start is normal, it just takes a few seconds to prime the oil pump and phasers. But they are probably defective if they continue to rattle, especially when accelerating.

Sounds pretty normal to me. Even after draining the oil and changing the filter out, I don't hear anything that would concern me with my 2.7T V6. I currently have about 15k miles on my engine.
