The belt was on in that video. The way that dipstick tube is shaking maybe its rubbing on something causing the noise. I personally don't hear any concern in that clip.

it makes the chirp with or without the belt. I was not ovely concerned About the noise until Yahiko mentioned that it could be a falling lifter. I get obsessed with problems until they go away. I wake up in the middle of the night thinking of solutions.
I cannot hear the chirp unless the vehicle is idling. My Subaru mechanic once told me that I shlould turn up the radio louder if I get concern about noises in old vehicles.
when my wife complains that her 91 Honda is making funny noises I tell her it’s 29 years old. Keep on driving it. She drove with a cracked motor mount for nearly a year. Should have listened to her.
"I get obsessed with problems until they go away. I wake up in the middle of the night thinking of solutions."
Talk to my wife about obsessive behavior.
There's never solutions, just more opportunities not prior thought of.
When you're older and wake up two or three times during the night to pee, you have two or three more opportunities to think about it. And stay awake.
In my Forensics video, I showed how I used the audio waveform from iMovie on my iPhone/iPad to document the sound of my motor. However, we have no database to account for a lifter fingerprint, which would be the frequency of the sound. And even that could be misconstrued based on something like the dipstick tube if it had the same frequency, or the dipstick itself rubbing on the interior of the dipstick housing due to vibration. It gets to be a slippery slope.
A good portion of my career work was brake noise, and we used frequency analyzers, vehicle Data Aquisition Systems with accelerometers on different parts of the brake system, and doing modal testing. The most we can do without sophisticated equipment is document the loudness of an identified noise, but not its frequency as everything used to reproduce the recorded frequency can impact the frequency value itself.
"Should have listened to her."
I found female test drivers to be more discriminatory of brake noise and issues than male test drivers. Try explaining to a bunch of salty male driver/mechanics they need to be in touch with their feminine side.
Mechanics are often hardened by a long history of wild-goose chases. "Bring it to me when it breaks." Sometimes it a bad motor mount. Or a bad ball joint in my case.
"I have a 2006 f250 6.0L with about 300k on it heads where done 40k km ago. Recently I have had a chirping sound at idle that speeds up with throttle, it's not belt/idlers/tensioner I ruled this out by removing the belt and starting truck. I stethoscoped the motor to better pinpoint the sound and it seems to be coming from the passengers side rear of the motor, I removed the valve cover and scoped it again the main sound was heard best above the standpipe on the oil rail and on the back edge of the head. So I removed oil rail and found my standpipe was snapped inside the oil rail. Thought that was the issue, replaced with new part. But...... truck is still chirping! So here's my question. Pushrods, lifter, or injector?
"Did you ever resolve this issue?"
Yes, it was a burnt out exhaust valve, the motor had to be removed and passengers side head had to be removed and new valves re-installed turns out valves are complete motor tare down, all they are accessed from the cam housing. Not a pretty job. Just ignore it till the motor grenades and buy a new motor as I found out at the end of it all it's about the same price. New is cheaper.

Reason: add title
A piston jet may have been the cause of the failure to the cam lobe. And little pieces of debris then caused the other failure.
In videos 2 and 3 (not yours) to me, I hear a heavy valve tap with the chirp which on a hydraulic lifter truck is a problem. They are somewhat similar to what I had without the chirp, but I had to be a hot engine at speed and in-cabin to get it. I just don't hear a chirp in yours, more like a light valve tap.
The VT-365 had a rating of 300,000 to 350,000 miles, which means 50% of the motors would have a major by then. Your motor has about that HP. I've never seen an actual public number for the 6.0 version, but I seem to remember around 250k being discussed with Ford people, with the chassis at a 10 year/200k projection. You're at 823,000 miles. International states in their manual that 0.020" cam lobe wear is the lowest allowable point, which is a crazy number. But at 823k I'm sure there is wear throughout your valve train. There's no standard for this noise. No one can tell you for certain "good to go".
To me, you have two choices at 823,000 miles, roll the dice and maybe it goes to 1,000,000 or tear it down for an inspection since you can't inspect all the lobes without the heads off. You can inspect the rear 4 of 16 lobes by pulling the HPOP. And if it's torn down with the heads off at 823,000 miles, for me, it's getting rebuilt. The labor is too intensive.
The only way to really find the problem is as you said tear the engine down and rebuild. Even with such a clean body and good running transmission I will be better off finding a clean used engine and reinstall after installing new head gaskets.
My buddy JWA on the van forum said to list van for $3500 and see it it sells. Tires, alternator etc are worth something. I could sell the the seats for $500. Just don’t want to spend the time parting it out.
If if I sell it I will get a gas E350 as I don’t tow. I can afford the fuel. Parts for the E350 are plentiful and cheap. I believe the gas van has the 4 speed tranny. That’s a bummer!
I plan on on driving it until dies or sells. It’s a great daily driver No more warming up the van or 5000 mile oil changes. I will use it for everything.
Unless the van oil pan is easy to drop, that would be the only way to easily get a borescope up in there to inspect all the cam lobes. The lifters, you couldn't tell I would think.
It may run to 1m. There's no way for me to tell that. If it failed on the road and you could pack up and leave the van at a salvage yard, I'd run it. It depends on how you can handle stranded.
I'd run. I don't think what you are hearing is what you think you're hearing, in my best Bara.
I am self insured so to speak. I told my wife if the van dies on the road we have 250 mile RV tow Insurance. I will put a rental car rider provision on the policy. Even if I pay $100 a day for a van rental I am good to go.
my knees crack and pop when I exercise. Yet at 57 I am still gong strong. The van has more miles than my bones. It’s noisy and quirky.
Utah here we come! I will keep you posted.
BTW Jack, I lived in New Jersey in the summer of 1984 when I interned for DuPont at their Parlin plant. It was a great experience. The bicycling was amazing in the Jersey farmlands. I cycled to the shore once from Jamesburg.
I would run it and not worry. I don't think the noise is indicative of impending failure.
thanks mark. For all I know the van has been making the chirp for a long time. I noticed when the windows were rolled down driving through a narrow canyon. The echoing caught my attention
That's a haul! NJ is an interesting state. I put an X on it then say that the line top right to bottom left is drive through country, from top left to bottom right are the places you want to visit. 1984 I was still commuting from the Asbury Park area to the state line, Mahwah. Monmouth Co is mainly horse farms, South Jersey down by Pete are the real farms, but it extends up through the Ford Dix area on the western side. Jamestown is a nice area.
You would only need the pan gasket, and a borescope would pass through the upper pad/windage tray. I've got two borescopes for my iPhone/iPad and they work great. They contain a light, the focus is fixed, but you can record pictures and video. That might alleviate some of your worries of the cam and piston jets. Warning, drain the oil the night before so any drips occur during sleep time.

If you think that’s a haul from from Minnesota to Jersey I took 6 months off after I graduated and bicycled for 6 months touring the the US, Canada, and Mexico. Ended up In Key West.
I think I will rent a boroscope and check the cam lobes. I may have sources for borrowing. Sounds like too much fun to pass up on a new toy. I finally figured out why you are named TooManyToys!
I noticed amazon sells horoscopes for about $35. Any suggestions?
