Bearings are designed to wear and are replaced when rebuilding an engine. The growing gap between the bearing and the journal increases oil flow. This increasing gap lowers oil pressure. Worn crankshaft, camshaft, and rod bearings cause a lower oil pressure.
How can you tell if a rod bearing is bad?
Listen for any kind of knocking noise coming from the front end of the vehicle. If there are sounds, and they continue once the engine is running, it may be a faulty main bearing. A low oil pressure warning light may accompany a faulty main bearing.
