This is why you have had this problem. You need to change the crank or convert to pressurised, but your crank journals may be damaged.
Sorry not to be more explicit guys, the crankshaft (and the rest of the engine) are perfectly normal, splash feed items and the crankshaft has perfectly normal oil passages for a splash feed crank. My bad photography I'm afraid! No pressure feed items were used or damaged in this incident!
The damage was caused by corrosion, as explained above; root cause, water or even coolant in the engine.
