I agree they are strange. They look rust color, but it was not rust. It's probably space mold.

Replacing lifters and rockers in Dodge 3.6L Pentastar after finding metal in oil filter

Is this real? I thought the 3 oil changes in 85k miles was a typo? How can this be possible?
If I remember correctly, he had UOAs performed along the way.

HPL is a super high quality, ideally formulated specialty oil that can handle such use cases.
Why have I never heard of these? Are there wildly expensive? I would be interested in using this magic oil.

I was discussing the yellowish color with a fellow bitog'er. The bright overhead light was a portable LED unit and I think it made the pictures look yellowish. There was no yellow tint in person.

Nothing magic about it. HPL has been very forthcoming about their formulations and approaches to blending product. They have hosted national visits for BITOG, are active on the site, etc. They also have often offered some discounts or specials to offset shipping. It’s a boutique oil. It’s not a 5-quart WM special. There is a price premium. For some applications that may matter, for others, not so much.
IIRC there are to different companies that go by High Performance Lubricants, it’s the one from Manteno, IL. There should be info in the site sponsor area.

I find this 5 year old video to be somewhat disingenuous, because my 2014 (11 years ago) has factory pins that float. I just looked and the pins all turn, even the pin in the bad rocker still turns.

If time was available and money was tight, would it have been possible to only replace the very few defective parts? Seems like you have a whole pile of good parts left over.
The slack adjusters really didn't need to be replace. There was nothing wrong with them and no squirter orifices were plugged. The only time I can image a slack adjuster would need to be replaced is if a bad rocker beat the contact point to death.
23 of the rockers appear by look and feel to serviceable, but I wasn't willing to use look and feel to judge serviceability because it's an 8-10 hour job to inspect and or replace all of them. I went the safe to my time route and replaced all of them.
Sure you can if you DIY, but that's a bit of a gamble. If the money is tight, do only the bank that's making the tapping noise and only replace the rockers, not the slack adjusters. Go with Melling rockers from RA which cost about a $100 for one bank.
But the other bank will likely fail shortly after anyways.
My engine was not tapping because I caught the bad rocker early. Of course with my luck, the bad rocker was the second to last one I removed. Had I gambled on which bank had the bad rocker, I would have lost the bet.
I appreciate that it may not be practical to check each part while doing the job. But it seems that if you did this job on a few engines, you could collect enough good parts that you could do this job in the future using only good used parts and new gaskets and save someone (or a few someones) quite a bit of money. I assume the parts would be interchangeable on most editions of these engines.
That may not be in the immediate financial interests of "the shop" but sometimes a customer needs a bit of help. I recall seeing a video of a young woman who had paid way too much for a used vehicle that was needed for work and her shop later found it was actually a rolling ruin (unsafe to drive for a start).
There is at least some risk that the wrong customer will come back later and say "you didn't do this job properly and now look at me". But the customer could sign off saying they knew and agreed to the job being done with good used parts.

Just changed my 457cc “Chonda” for the 3rd time - and could still see fine glitter in the oil … Hopefully that’s only bcs of very low hours …
