Previa Diesel said:So the problem is confined to the main and conrod bearings? What's on the camshaft?
Actually, it seems confined to the conecting rod bearings only. It seems very very rare to have an issue with the crankshaft bearings on these engines, and I've not heard any chatter or seen bad camshaft bearings. If one had oiling issues then who knows, however as a general rule it is the connecting rod bearings only. It seems to mostly be the top shell, which makes sense: It takes the brunt of the shock on ignition.
