Sounds like an oil cooler to me but like I said, Ford Gold at the proper mix isn't the culprit in 10,000 miles.

I can't translate "oembsainless oil cooler".
It really sounds like the oil cooler is not performing with enough flow. The historic oil cooler clogging over time from the Gold coolant is clogging within the plates. that's not happening in 10k miles.
I have two cut apart oil coolers that show debris clogging the intake of the oil cooler as the coolant is flowing onto the plates. So either the motor wasn't cleaned as it should have been, the coolant passages were protected from rusting in storage with a coating, or all the debris was not fully purged from the radiator and heater core, which is most likely the case.
If the debris is not seriously wedged in place, a backflush of the cooler can partially or fully clear the debris. That is what I would try rather then a "flush" that only continues to trap and debris with the normal flow direction. Then if that doesn't work replace the cooler. Keep in mind there still can be retained debris to come out of the woodwork iif that the source of the issue.

I would suspect the system wasn't properly cleaned. IMO, not many dealerships will take the time necessary to do a good job cleaning a dirty system. Not many use distilled water either, at least from my experience.

This was not done at a dealership, he has his own garage on the side and he does nothing but 6.0 and is a ford diesel master tech, this is a brand new engine and is just shy of its 2nd oil change, hence I find crazy oil cooler clogging up now, so gonna looking into a new cooler and coolant filter of go external oil cooler.

Oh, I know a guy who clogged way earlier. Nylyon.
Have you talked to your independent Ford diesel master tech about the issue? He did the work.

He works for a local ford dealership, and yes, did talk to him but he has no idea other than the cooler is clogging, now just deciding which way to go with the wallet lol

He's definitely not the first one to have this repeat clogging to happen to.

Try backflushing the oil cooler first, it's cheaper than an R&R right now:

No, but it is not uncommon for this to happen again when the cooling system wasn't cleaned enough when they replaced the cooler. And yes, the Ford Gold has also been suspect for a while to add to the equation.

Once again, the cooling system not being properly cleaned would be my first guess. Lots of junk can hibernate in the bottom of the radiator and then break loose. And yes, the gold has been a source due to silicate fallout but, not in 10,000 miles with a properly cleaned system.
Keeping an eye on the Deltas is a good way to halt the chain reaction if you act on it.

Once again, There IS gold coolant failure BECAUSE the cooler is clogging up. It's a domino effect. First the cooler clogs due to junk in the system. Then the coolant overheats in the egr cooler because there isn't sufficient flow. Due to this overheating the coolant fails and clogs the cooler even more. This isn't just simply one failure. It's a chain reaction that eventually results in heads lifted and total destruction of the engine.
