So, my d15b vtec had a crimp in the oil pan, and I'm going to use the one off of my d16z6 instead of buying a new one. Thing is, when I drained the oil from the d16, there was like a gallon and a half of mocha latte from the head gasket being blown. When I take it off, I know it's gonna be chunky monkey down there. What would you guys use to clean it to get the gunk out? I haven't taken it off yet, but I know it's gonna be ugly.
