Once the engine starts and is running and the oil pressure is up to operating range, the journals ride on a nice, thick layer of oil; thicker than any surface asperities. Journal bearings don稚 like starting & stopping and under these conditions are subject to a thinned down lubrication condition where asperities can make contact, weld, oxidize and tear apart. That痴 one of the primary ways they ear. That痴 why people who run diesels 24/7 let them idle for extended periods.
