Yes, holes in the exhaust cover plate are fairly common. And yes, it will squirt water into the exhaust ports and yes it will find its way throughout the powerhead and do extreme damage. OK, having said all that, it is hard to tell from here just how bad it is. Water also enters the exhaust housing right below the powerhead gasket to keep the exhaust housing cool. All that goop you see is an emuslsion of gas, oil, and water. Various factors contribute to the goop forming, mostly (cold) temperature. Bottom line is at a minimum you need a new plate and gaskets. If you want to go in and check the con rod bearings, that is your call. But when a rod comes sticking through the side of the crankcase, the party is over.
