Dexcool sludge or bad oil cooler?

I will be pressure testing the oil cooler this weekend. Is it possible for head gaskets to cause this without a pressure issue? I'm really thinking either the oil cooler or cup o ring. The oil cooler is all shiny , I doubt it's original. Maybe I'll be lucky and its taking a lot of time to get the sludge out.
I think the color of the water drained is continuing to improve, must have been a really dirty system.
Still got sludge build up in the system. Going with some more cascade. May order the gm heavy duty cleaner. The oil cooler looks so new that I think it was a combo of that and green mixed with red.
I went with 2 caps of the liquid. Last time (still dealing with this) I filled up I put two of the gel packets in.
Still dealing with this issue. Lost count of how many times I've filled up with water and cascade and driven the truck for several days, probably at leatst about 12 times or so. The first picture is after the bucket Sat overnight, the second is after I stirred it up a bit. I'm wondering if something is getting oil in the system but I still have no pressure issues and it still has a greenish tint like that crap that was in the system from the bad mixture. Could it actually take this long to get the system clean?

I honestly would be sick to my stomach after that many flushes. I feel your pain man. I wonder...would some of that purple power clean stuff be ok to run in the system or would it kill the hoses and seals
purple power will bubble. cascade will not. You don't want to be foaming your system up and not allow any room for expansion when the coolant warms up.
I would be feeling Mich worse about it if I didn't have the lly engine sitting in the garage for the swap. I would still like to get this squared away and pull my camper through the summer while I take my time prepping the lly. I think I am going to order some of that high speed gm cleaner and see what happens with it. After about five flushes I was going to install a new reservoir and put the thermostats back in. I noticed a bunch of crap cakes inside of the bigger hose that leads to the reservoir and had a change of heart and kept flushing.
