Oil looks like a Milkshake

[basstender10.6]

Last summer, my 1999 5hp evinrude 4 stroke was leaking oil from the midsection after being run for a while. I did a lot of research and I thought it was a bad head gasket. I just replaced the head gasket and put the motor back together properly. I went to start it up and it was running fine. But I had the hood off and noticed a little water dripping from the block into the engine "bay". After a 15 minutes it spit milky oil out of the breather hose for the valves. I shut it off and checked the dip stick which was milky. Then I drained the oil which was a complete milkshake. So, does anyone out there think that they can offer any advise to someone who is about to give up?

Considering that did you everything correctly, proper torque, cleaned all of the head and crankcase surfaces spotless before replacement I would say the head could be warped.

Oh gosh.. here I thought I finally found the issue by changing the head gasket, but it looks like there is way more to this problem.

Well that's a could be on the warped head but it sounds like you may have swaped one problem for another. Did the motor still leak oil in the original location and it sprung a new milkshake leak elsewhere after you replaced the head gasket? Is there any area of discolored paint on the power head that may show signs that it overheated in the past?
