Either a breakdown in the pressurised oil supply or faulty/incorrect size big end bearing shell?
While engine stripped check entire oil supply system-strainer,pickup,oil pump,oil feed jets,pressure relief valve but I imagine faulty oil supply would affect more than one set of shells.
Re bearing shells-any clues from code numbers?- see relevant section in Haynes manual.- assuming engine has never been dismantled from new this points towards incorrect size/clearance from original assembly?
