I seem to remember the owl noise description now. I think it was related to the wastegate solenoid, which I've also had replaced.

I'll be replacing mine soon but I can't find one lol. I don't like to buy things online so I called O'reilly, Autozone, and Napa and none of them seem to even be able to order one. I'll call the dealer in the morning and that will tell me if I'm buying online or not lol.

If you decide online, I purchase the OEM parts I need from here. Every time I need a part direct from the dealer it's list price.
Possibly part number BC3Z-9E882-A but you'll want to confirm that. A local shop replaced mine when I had other issues for them to work on and I don't know the specific part number.

I'll try to confirm that, but are there any other places I should be looking? The odd thing is that after a minute or so the noise goes away and I don't hear it until the next morning.

The truck is a 2011 F-350 King Ranch, it did this bone stock and it is currently DPF deleted and it's still doing this. EGR is in place but un plugged.
Completely normal and it's coming from the turbo. Mines makes this same sound only during winter months and currently have 161k miles so I don't think it's a problem.

Additionally, if you don't have the mini air compressor noise at shutdown (all temps) your wastegate solenoid could be fine.

Thanks! I'll call all the parts places again, I was calling it a wastegate solenoid not a vacuum valve, hopefully they'll have something lol.


It sounds like an air compressor for about a minute when I shut it down if it's at operating temp.

Another question is while I'm trying to find this hoot noise I'm turning it on and shutting it off a lot but when I shut it off it makes the same noise as if I were to floor it and let go from the turbo but instead of 1 "bark" it keeps barking quieter and quieter until there's no more air passing through if that makes sense. If it's warm it doesn't do that.

There is also part number BC3Z-6F089-A (Actuator Assembly). But... it seems reasonable to think the other part is what makes the noise at shutdown plus it does word it as a solenoid.

stsmark is starting off with a positive reputation.
The noise is normal for the dual scroll turbo, it has to do with airflow and a harmonic caused by the clearances in the compressor being more open following a cold soak. Some do it some donít based on the tolerance stack during assembly. After a couple minutes things warm and it goes away.

Mine sounds like the horn is honking for a few minutes on a cold startup in winter..have had my co-workers tell me my truck sounds like sh-- many times....

So I did a lot of stuff, I decided to just go through everything I could and here's what I found.

The worm drive clamp from the air box was loose (someone replaced the filter but forgot to tighten the clamp)
The air filter its self was super dirty
The intake was disgusting as seen in the pics
The lines on the fuel filter have a lot of play (I assume this is normal for a push to connect fitting?)
The fuel filter housing moves a bit (again I assume this is normal after looking at how you take it off)
Power steering fluid was a tad too full


What I did:
Tightened the clamp on the air box
Smacked the filter to get a lot of dirt out (getting a new filter tomorrow)
Cleaned as much of the intake as I could
Unplugged the fuel filter lines and took out the fuel filter as if I were to change it. Filter looks good (according to receipts they were replaced 4k miles ago) and put everything back together
Drained a little power steering fluid out, may be time to change it
Electrical taped around that intake elbow where those holes are in the post where I showed how dirty the intake was


After all that it didn't make the owl noise yesterday or today. Yesterday it got below freezing and usually the colder it was outside it seemed like the more it would make that noise.

Random observation, is your coolant orange or red?

I'm pretty sure it's orange, I'll check tomorrow though.

Well I hate to bring this back but the noise is there again. The air filter has been replaced and the solenoid still hasn't been replaced. Been getting jacked around on that but that's what happens when you're a budget shopper I guess lol. Anyway that's on order from ANF white bear lake.

I'm 99% sure this is a exhaust noise from the turbo as I had my dad start the truck up and give it gas when it made that noise and it gets louder as the RPMs increase but goes away very fast. I still haven't been able to find a leak in the downpipe however I also do not have a powerful enough source of air.

Another thing I've been questioning is when I open the hood I get a smell of coolant. I'm not loosing any coolant in either system that I can tell however I did do some research on coolant leaks with these engines and a fairly common one is a fitting on the turbo leaking (the radiators don't appear to be cracked in anyway). This might be the cause of the smell but do you think it could also be the cause of the sound?

EDIT:
The reason I believe it may be is because when it's been sitting for a while all the pressure would've leaked out of the system and when you get it warm it will build pressure and make the seal work temporarily. This could also be the reason why when some people got their turbos replaced it went away because that fitting would've been changed out, yet others haven't has issues with their turbos because it could be a coolant pressure leak. That's where my hopeful mind goes anyway.

2011' and 2012 had the turbo fittings that would leak. Check the valley of the motor for evidence. It might also just be the degas bottle cap. An easy fix for minimal amount of money.
