He's not on the same page as you... he replaced the cooler and then flushed it, big difference. After the oil cooler replacement, you should see 2-6* difference. He's at ten difference and when he's at a 15 difference, probably going to need to consider replacing that cooler again.
Your just waiting to confirm the milkshake in the oil pan... but it hasn't totally ruptured yet, you still have a chance.
I have considered doing the bubble test to check for blown head gasket. The test where you drill a hole in the top and add a tube that goes to a glass of water. Is that a good way to check for a blown gasket?

You could do that, but then you have an extra hole in your Degas bottle, another place to possibly leak. Since your egr is deleted a much easier test is what has been described in an earlier post.
Check your coolant level to make sure it is at a good level. If you have the sticker on your degas bottle use that. If not and there are two molded levels on your bottle use the lower one as full. If only one molded mark on it use that mark as full. Confusing, I know...there have been update stickers and updated degas bottles. Anyway, drive around until your truck is at full operating temp. If you have an OEM thermostat that is working properly this will be around 192 degrees. Pull over safely and slowly release the pressure from the degas cap. Tighten it back up and drive around for 5-10 minutes while keeping the temp relatively close to that same number. Then pull over safely and slowly open the cap. If more pressure comes out your headgaskets are toast.
I made the following so I can check for blown head gaskets, You put it in line with degas bottle and than run the gauge out and around to your mirror and secure it there, Than take the truck for a spirited drive, You should see pressure rise than become steady, once that does do a couple of hard runs and see if pressure spikes and at 15/16 psi ( cap release pressure) you will see pressure drop. if so you have a bad headgasket or streatched bolts even possible a cracked head, either way you need to pull the heads and change the head gaskets, If you do than you also will be sending your heads out to be checked and you should stud them at that point also. Also make sure you have a NEW degas bottle cap before you before this test as I have seen some that have failed and will release pressure pryor to 15/16 psi and give you false readings.
Pressure gauge for checking cooling system pressure.
WatsonR is right, you don't need to keep this up. You need to replace the cooler now. I was stating that you were doing the right thing by cleaning as much as you can before you replace. The longer you put it off the more problems you may create for yourself.
