No surprise you have chocolate milk in the oil cooler which contains the same oil that's in the pan.
I'm betting your motor has an internal issue causing the intermix.
I would have it hauled to a real mechanic who can determine the exact issue. Your local POC members should be able to provide you leads to a competent wrench unless you're comfortable dropping and rebuilding yourself.
The cooler came in but without new O-rings so I have to wait a couple more days. Decided to swap the AOS while I'm back there. The lines are also filled with sludge. Would like to remove both intakes to free up some of the lines so I can clean them. Tried the drivers side but discovered the fuel rail is attached somehow. How much of a headache is it to remove the intakes? Am I at risk of breaking any lines?
Agreed will be taking it to my guy when I get it back together.
I just didn't want to waste any money if its the head.
Wanted to figure that out for sure first.
Interestingly, when I drained the oil today, it showed very little signs of contamination. Doesn't look anything like what you see in the pics or in the coolant reservoir.
