Oil cooler rupture?

[JayAF98]

Is this a sign of an oil cooler rupture? Or something more serious? Consistency of mud about 1/4" floating on top of the coolant from the first drain during a flush/oil cooler replacement/egr delete

So, I have the new cooler of course. Chances are I can't finish the flush in this condition and it will probably clog the new one when I finish the flush right?

I expect you have coolant in your oil too.

I've wondered how you can flush with a ruptures cooler myself...

You can't flush it with a ruptured cooler. You have to repair then flush unfortunately. CHANGE YOUR OIL AS WELL WHEN YOUR DONE!!! Dont't forget that.

Were you running a monitor in the truck when this happened? If not let me know if I can help you out in getting what you need.

That looks EXACTLY like mine did when I bought my truck. I flushed the crap out of mine. probably 20 times before I installed the new oil cooler. I havent had any residue show up in the new coolant, but be sure you use something to clean out the cooling system. I ran a very small amount of diesel in mine when i did the flush and it seemed to clean the hoses out well. All of that gunk is throughout your entire cooling system.



That is the gunk that came out of my degas bottle after a few flushes.

When this happened to my 6.4 the dealership that did the repairs ran simple green through the system numerous times. Truck smelled like simple green for a while but it did the trick.

You need to do a couple of oil changes too. Like change it run it for 50 miles or so and change it again. I would do it 3 times just use some cheap 15w 40 and last fill use yoir normal oil. Aftet the new oil cooler though.
