Then the dealer is giving you an aftermarket filter if you are getting a new cap each time.
I'm guessing it's all one piece?

Our local dealer does the same thing if the truck has an aftermarket on it or customer requests it.....why is beyond me.

 

dont know but like i said i get a new cap everytime i get a filter from local ford dealer.

 

no, i buy the cap seperate the cap has never came in a bag or box. always has the oring but the filter is in ford box.

 

Add me to the list that is concerned about that cap. There is no way you are filtering your oil if you throw in a Ford filter with that tall cap.

 

You can lead a horse to water

 

again. it's what i got from ford. if it's wrong from ford how am i supposed to know if they tell me it is the replacement? i understand your concern and now i have one, but I can't do anything till they open Monday when they open and can call them. but i don't think this is what is causing a squeal. which the original post was about and don't get me wrong, i do appreciate the fact that it was pointed out.

 

Meaning? in your infinite wisdom please enlighten.

 

After thinking about it for a while that very well could be the issue. Iagain, have to wait till rain stops to climb under but makes the most sense at this point. and just took it for a drive listening and makes more sense after listening to it.

 

Did you need to move the collector around to line things up when you put the turbo back in? It's possible as mentioned above the bellows is leaking now, and re installation maybe made it a little worse.
I was fighting a boost issue a few months ago and finally realized it was due in part to leaking bellows. I went with the BD up set up, works well.
When you get time to, crawl underneath and look closely for soot around any joints, and also and gasket surfaces like the EGR pipe or EGR delete pipe if you are deleted.

As for the oil filter, I think the posters are a little perplexed because you are stating the dealer is giving you a separate Motorcradt filter and cap, however you are running an aftermarket cap, and those always come with a filter glued into the top of the cap, so one piece.
There are guys that will actually take the aftermarket filter out of the cap and then install an OEM filter with the same cap.......problem is you don't filter any oil, it doesn't depress the button at the bottom of the oil filter housing.
There are quite a few vids out there of damage caused by running those filters.

Here is one by a well known Ford tech

 

Yes, did have to move the up pipe around and may have cause it to get worse which did once i re installed the turbo. I'm really leaning towards this now cause after driving it a little while ago seems it is coming from that area. Looking up a new up pipe now. as far as the filter, am getting with ford tomorrow to find out what is happening. the only reason i replace the cap at each change is cause i has seen a few get hard to come off after it's been on awhile and then end up stripping the top and making it harder to remove.

 

You ask "how are you supposed to know?".

All I (we) are trying to do is inform you - your choice after that.

I am not trying to belabor the point, my earlier post was simply due to the impression that you had just accepted the filter cap as being OK simply because you got it from a dealership.

I do think if you run unfiltered oil, then it could be contributing to the squeal problem (unless it is a simple exhaust leak).

Although I am interested in how it all happened, I am not interested in making you feel like we are "piling on".

Best of luck!

 

Again, don't get me wrong. I'm glad ya'll pointed it out and sometimes reading post this can be taken the wrong way but i do appreciate your input and yes after looking up the cap online is defiantly wrong so please do not stop with the input. that's why i posted to find or eliminate the problem. I am getting ahold of Ford tomorrow and find out what happened. I never really paid much attention due to coming from the dealer figure they would not sell me the wrong part when it clearly was supposed to be for a 6.0 powerstroke. I can take criticism so please bring it if it is productive. once i find out if it is for sure the up pipe i may go ahead and change the down pipe and go all the way back. main thing is getting this annoying sound to stop

 

A number of us are confused as we can't understand why a Ford dealer would sell an aftermarket cap, especially if it's with a Motorcraft filter. They don't belong together.

The cap should be standard Motorcraft cap 3C3Z-6766-CA along with a Motorcraft FL-2016 filter element. Those caps can be reused. They can come off "hard" because the o-ring seals in compression sideways, between the cap and the housing. They do not seal "bottoming out" so there is no reason to torque them more then first contact cap lip to housing. But until the o-ring clears the housing you are always wrenching against it's resistance.

If you are doing as lastly stated, using a FL-2016 filter element in a tall aftermarket cap, there's excessive gap for oil to bypass any filtering, and you can have issues with the valving within the housing. It's very possibly the squeal may be from that, or not. You'll find out when the correct parts are assembled.

 

I just ordered a replacement part # 3C3Z-6766-CA which is what ford calls for and should be in a few days. when i first got the truck the nut molding on the top snapped off and played hell getting it off so from that point on i would buy a new one each tim. just dug out the extra filter i bought but can't find the extra cap i had. pictured is the stock 2016 but was trying to find the cap to see if there was numbers on it just to make sure.

 

Some people really like to wrench on those caps. I don't even bother torquing them, just snug it up good once it bottoms out. I can see where one might be tempted to replace the cap, but you can get a lot of changes out of one cap.
These engines cost enough to change the oil the way it is


If you do end up needing the y pipe there are a lot of good options out there.
