Blown Engine

[Guest flossy]

After fixing the odd steering, i was driving along today at about 35 mph when a deluge of blue smoke started pouring out the exhaust and oil out the engine, it looks to be comming out some where round about the bottom of the dip stick at the back of the engine.

Could this be a cracked head and oil comming out the gasket or does anyone have any ideas what it is and or is this a rebuild
