6.4 ticking/ knocking video

I posted this over on another forum as well, but figured I would have the best luck here. A few years ago I made a thread about the "tick" that Ford claims is normal. The truck in the video is mine, and it's had this noise since it was brand new. Only lately, I have been noticing it more. I have had it into Ford twice now, and was told it is normal. All I am trying to find out is if anyone else on here notices a similar knock from their trucks.

that sounds more like a rod or lifters, My 08 makes a ticking nose but nothing like that. there a thread about the ticking somewhere here.But not sure where it is. just look for it in the forum.

Let me guess, when you drive it loaded or not, it makes the noise more noticeably around 2000rpm as well.

Ford tells us its normall too. Sounds like lifter clatter or as if it were an oldschool pushrod engine with too much valve lash. being the best way i can describe it.

I have had trucks that when you shut off 1 injector at a time the noise would go away, indicating a rod bearing.

So does the noise from the video sound like what Ford claims as "normal"??Actually after 2000 RPM's it gets hard to hear the knocking.

When ive road tested the "noise" effected truck(s) in question, you hear it at an idle and with no load *neutral or park revving it* and once you get on the road and lightly accelerate and it makes one hell of a clatter around 18-1900 up to 2100rpm. Especially if your going up a hill.

Ive had our FSE come listen to some of the trucks ive had picky customers complain time and time again about the noise and said its normal. To me its not. I cant touch it til it comes apart or the FSE says so. Or ford releases a TSB....

Best advice i can offer, pay it off and get something else. 6.4s are not something you want to keep once the warranty expires unless you have alot of money to dispose of, or until components become cheaper SIGNIFICANTLY cheaper.

But as i mentioned, only way to telll if its a rod bearing is to shut the injector off to that cylinder and see if the noise goes away, or turn the engine by hand and listen to the oil pan. tape a stethoscope to the pan while you turn it listen for the click that it will make.

Has the truck ever been looked at for over fueling conditions? If enough fuel gets into the oil it will thin it out and cause bearings to become starved for lubrication...

Food for thought...

No it hasn't, but I take UOA's through Blackstone on almost every oil change. All of them since deleting the DPF, with the exception of the last sample have read as there basically being no fuel in the oil. The last sample came back as having 3% fuel, and 22 PPM of aluminum. That's the most amount of fuel I have had in any sample with this engine. All the other metals are in check, and aluminum has always read a little high on my engine. Universal averages of aluminum are around 15 PPM, and mine was 22. Not extremely high, but not great either according to them. Bearing material has never been an issue in all of the samples.

Thanks for your input

my truck makes the SAME noise. I have taken it to 7, YES SEVEN, different dealers and they all say nothing is wrong. So i continue to drive it, and often get asked "wtf is that fluttering/ticking noise" and i just smile and say "it's a ford"

sorry man, situation sucks.

kane mine sounds exactly the same, it makes the noise when revving it up in park and until about 1600 rpm on light accelaration its the loudest when i really get on it you cant really hear it because of the intake and 5" straight pipe,
