 that thick creamy sludge is water and oil mixed. I had a 6.9 international that the head gasket blew, nvr overheated but would deff was allowing a lil water into the oil system once it was shut off. when I tore it down, there was a thick creamy sludge in the valve covers. unless you know deff which side is leaking, it would b best to pull both sides down, replace all gaskets of course and also drain the oil and coolant, flush both and then reservice.
