So first thing; if you're coming in to knock the ecoboost or start a 5.0 vs ecoboost debate, hit the back button right now

For everyone else, on cold start today it made this noise

Sounds like a 90's cummins... As soon as I started driving it sounds totally normal and hasn't done it since...

Kinda sounds like it's not getting oil on startup to me. Yikes.

most likely injector tick.

have you checked oil level just to be safe? no oil light or anything?

ns_redneck

check oil to be sure it's good. but I would show your dealer this video and see what they say.

I wonder if that is the wastegate rattle that I've read about?

chimmike

Does it keep doing it at idle at stoplights or anything?
seems like the wastegate rattle would happen all the time, not just on startup.

dlbb

kinds sounds like the cam related issue. take it in.

Only happened twice on cold start. A good friend of mine's a service manager at Ford so I sent him the video, he thought it sounded like the truck wasn't getting oil in the top end. But that's just from a video... I check the oil every second tank of fuel, and it's full. Hasn't burned a drop.


That noise is most definitely not injector tick.

dlbb

the cam issue is related to lack of oil on the cam.

did you change to full synthetic yet? i highly recommend it for longevity.

here is the worst horror story for your reading nightmares. please take it in asap.

Sounds similar to this one with the wastegate problem. Keep us posted what you find.

That's not wastegate or injector rattling, I have heard both before. You definitely should take that in. I agree with the ford service manager you showed the video to...any aftermarket engine parts installed lately??
