2011 ecoboost noise on start up

Wow! Great job everyone! This thread rocks... Seriously need to have a Ford tech read this thread in its entirety...
I have a 2011 F150 Ecoboost XLT 4x4 with 52,000 miles. It just started making a rattle noise at startup, nothing like the grind or missing sounds of the previous videos. The rattle sounds like it's coming from the front driver side wheel well side of the engine near the turbo tube. It only makes the noise at cold start ups but then goes away. I'm going to have it looked soon. I take very good care of it & it performs great. I wander if it could be turbo wear from the ethanol in the gas. We'll see what they say, hope the extended warranty coverers it.

If you are out of warranty and it is the pump fordtechmakuloko on YouTube has a video that shows how to replace it. Looks easy if you can turn a wrench. Part is expensive, but cheaper on eBay. Look for part

1. It doesn't have to be raining for the CAC issue to occur, though that has often been the case. A dew point and outside temp within a value of 10 of each other seems to be the best conditions from all I've seen, experienced myself, and read all over.
2. If the vehicle had this happen, and the operator didn't pull over, turn off the motor and clear it out soon enough, there could be a number of components damaged, as this has happened to several people (search the forum and you'll find a few examples).
I doubt any of this is related the the unique sound many of us have gotten on startup. Still trying to pay attention to this thread (which has gone very off track lately) in hopes someone else has better luck than me at my dealer. It's the A/C compressor spinning up they told me....right!
Hope we identify it before I hit 100k and the warranty poops out...

If you're just giving it minimal power it seems to move fine albeit quite sluggish if you go 1/2 throttle or more it immediately starts shaking and sputtering and then into limp mode.

I fear you may have lunched a plug. For some reason these plugs carbon arc very easily. If this is true, then try to get the old ones. You'll see a black feather on the side of the bad one. If you don't have too many miles on the plugs, you can just change the bad one and move on.
I suspect the reduced power is from timing that is extremely retarded.

Finally heard back from the dealership. Tech found a failed coil and also recommends replacing all the spark plugs for $310 plus a $100 deductible. For starters, I just replaced the spark plugs 4,000 miles ago, so if those are bad, there is something WRONG, secondly, it doesn't cost $310 to change spark plugs, and lastly, they never mentioned anything about the intercooler or the start up sound... and it's been there for a week now

Went up there, the mech said he just recommended the plugs because of the mileage, he didn't actually look at them. Talked to him for a while about the intercooler issue and he said he would do the TSB on it. Then I asked about the start up sound, he said he hadn't heard it so there was nothing he could do, but then he suggested we could go start it up now and see if it does it, since it's been sitting there all weekend. We walked out to start it and boy did that truck sing perfectly. He will submit he info to the Ford Hotline in the morning to see what they say, but he looked at his computer about trucks with the same issue and Ford had them replace the timing chain, chain tensioner, and cam phasers. Truck will be there until at least the end of the week. Although from reading this whole forum, replacing those things won't actually fix the issue. I have to start somewhere though, the mech has to take Ford's word, not mine.
Will keep yall updated

The documentation though is key... Get into their system that you had this prior to warranty expiration.

The Tech is believing it is skipping a beat when starting throwing the timing chain about ? : >/ It's your call. Slip some inexpensive Platinum's in to see what happens.

If you see Murdr's thread the truck threw a piston skirt. I have a feeling these things are related. Whether or not the skirt goes first and blocks the pickup starving the motor and then the chain goes, or the sound is piston slap.
