I had 73k on my truck and deltas over 28 deg. When I cut open the old oil cooler, it wasn't clogged, but had a scale type build up on the internal surfaces (see pics in thread below):

This may have caused an inability to effectively transfer heat. Perhaps this was caused by the presence of hard water in my system from the previous owner(s). I was expecting to see it clogged, but it just wasn't the case on my truck.

Yes, it usually runs about 5-8 degree difference. I also installed a coolant filter at the same time as the Oil/EGR cooler change out, and found a good bit of sediment in it when I cut it open on first changeout:

Nope! If theres coolant flow in sufficient quantities, the cooler wont fail. Lets look at this, 8 gallons or so of coolant capacity. Maybe a pint or so inside the cooler at any one time under optimal conditions. That would be difficult (if not impossible) to "flash boil" the entire capacity with just that much coolant exposed to the heat. Now, you're saying a smaller, restricted flow will do it? I don't rely on theories, I want to realisticly see things.

You would think residue from some oil coolers would have been analized to see exactly what elements the residue is composed of. Not many things possiable outside of what has been discussed. Casting sand sounds reasonable until you consider tempatures required to melt sand certainly are never present. That leaves us with "something" acting as a catilast for the sand and causing the blockage. The silicate could possiably be the catalist but doesn't cause problems with other engines because A. Other engines retain less sand , B. Operating temps differential , C. Difference in cooler desighn,passage size,coolant volicity through cooler. D. Substance left behind from casting,cleaning or other procedure unique to International. That now begs the question,why the International branded engine suffered less than Ford branded. Is it because of different coolants used?

Casting sand can remain adhered to a poorly cleaned block (doesn't have to be "melted") following the casting process .............
Thermal forces and even chemical action can free it up.
International engines have had oil coolers plug up. I mean why would International install filters if they didn't see a need?
I think we know that there were head bolt torquing issues early on, so a poor cleaning process on many blocks is not that hard to accept.

well if the Oil cooler clogged (Coolant Half) its not moving the Volume of coolant threw the EGR Cooler or Oil Cooler
Anyone agree^^ or NO???
So does that mean if Its (as in Oil Cooler) is clogged Bad enough that the Coolant flow (as in NO FLOW) in the EGR Cooler would almost be Sitting there (Very Little GPM) like getting Boiled in a Pan
So now where down to what DChamberline mentions Does anything Happen to the GOLD even if it does Boil????
Iv seen more Oil Coolers Clogged with Casting sand that Golden Goo and thats only a small amount of the Folks that have Cut them open on FTE and posted a Pic

Don't forget that one of the most common constituents of sand is silica. So if you find silica, you don't know if it was casting sand, or came from the coolant. Unless you know for sure the casting sand used in the casting of 6.0L blocks did NOT contain silica.

So your saying the 2 things here Casting Sand Or Silicate can Look the Same????

I would guess that if you scraped silcate from the coolant out of an oil cooler, and casting sand, there is a very good chance they would look the same, yes.
I don't know that for sure, however. Because I haven't done it.
I would imagine that the coolant in an EGR cooler that has a significantly reduced flow could boil, and it could also after it boils get even hotter than that as steam. Then be cooled once it reaches the main flow of coolant again. The expansion that would occur should show up in the degas bottle possibly as puking, though.
But, assuming this is happening, someone should be able to heat gold coolant mixed 50/50 with distilled water in a controlled pressure vessel until it boils and see the results. If there is silicate residue left behind, then that could be evidence of a problem.

I think they could look the same too just for the reason they come into contact with Gold Color Coolant
But Iv definatly seen 2 Diffrent color Substance (Like That) plugging an oil cooler
Ones in my pic and another in another members pics the Website used to let me post both but I think I can only do mine now I will try to get Both

Here is mine its definatly grey in color
its not cross contaminated from the cut either same stuff if you were to dig back in the junk plus the oil path is clear
Im thinking this is the casting sand
Here is one thats golden goo
