I had a blown head gasket and water got in the oil. Gasket issue is repaired. Oil tank drained. The dry sump has no drain plug and I can’t get the pipe out of the pan with the engine installed. I used an extraction thingy and sucked out all I could through the tube. I took the valve cover off and wiped out the head as best I could. I got some cheap oReilly oil knowing it was only to clean things out and drain again. Warmed it up and the oil is pretty milky still. How many oil changes do you think it’s going to take to clean it out?
