Is this correct?? I only find 3 in the parts diagram...

Correct for the bottom between case and cylinder , 2 dowels on Clutch side , then between the cylinder and head , one dowel should be at the front of the engine on the timing chain side , the other on the clutch side to the rear
The leak would have to do with the head/cylinder assembly unless your water pump seal/shaft is bad , that's about the only way you are getting coolant into the oil that i know of
Unless like mossman77 mentioned and you have a warped head (check it with a straight edge to confirm) , but you should see coolant on the gasket when you disassemble the top end (it should be dry if the coolant was drained before dis-assembly)

(even a slight amount might allow it to leak) , have you tried draining the coolant , and holding a rag over the radiator opening and slightly pressurizing the system with air ?? ,(this may require 2 people) , if there is a breach in the gasket , the air will tell you where it is coming from , you should be able to hear where the air is going and trace it to the leak
Unless by some odd issue , you have a crack in the case , the gaskets or the dowel would be my guess as to the breach location

What about the dowels , were they where they were supposed to be ??
Did you try blowing air like i mentioned ?? , it might tell you something , and it would have been nice to do that when it was all together , it could have told you where the leak was originating from , also , make sure there is nothing wrong with the case surface itself , unless the case itself is cracked somewhere , i don't know of anywhere else it could pass water like that , with the exception of the water pump seal or shaft leaking
Maybe someone else can make a suggestion as to what it might be , as this is all i can come up with , you could also PM Ken , the owner here , he might have run across this situation in his shop , just look for the user name crfsonly in any post on the main forum page and go to his Profile and PM him
