Water in oil 2007 AR210 help!!

when you took the lid off the air box did you see chocolate milk looking oil sitting in the air box cover ? This usually happens due to the additional fluid being introduced and the breather spits it out into the air box. The other thing that happens at idle you will see steam coming out of the pisser. I think the reason the breach occurs is from cavitation, as the aerated water flows through the cooling channels it does not cool properly causing the aluminum to fail.
 
I have just tested the compression and its bouncing off 210, over 200. I think I will just change the exhaust manifold, take me 20 min to install it. I'll probably buy a new one. A welder I know is going to look at it. He welded my other engines block and its been fine for years.
