Look for a cracked cylinder wall is all that I can think of.

Was the engine running up to temp? Are the t-stats stuck open?

Thanks guys.On closer inspection corroded cylinder head letting water into combustion chamber through and underneath head gasket.Water in oil still a mistery.I'm suspecting corroded sump???Any ideas?
