Additionally, issues with the crankshaft bearings, while usually associated with low pressure, can in rare cases lead to a pressure spike if the bearing clearance is excessively tight, creating an unintended restriction. A blockage in the main oil gallery, often caused by a collapsed hose or a piece of disintegrated material, can create a significant restriction.
How Bearing Clearance Issues Trigger High Oil Pressure
High oil pressure is a condition that often flies under the radar until a dashboard warning light illuminates or a critical failure occurs within the engine. Another common issue is a malfunctioning pressure relief valve; if the valve is stuck in a closed position or its spring tension is set too high, it will fail to open and release excess pressure, allowing the system to reach dangerous levels.
The oil pump generates pressure to ensure a constant flow reaches critical bearings and moving parts. While low oil pressure is commonly discussed as a sign of trouble, high pressure can be equally problematic, indicating restrictions or malfunctions in the lubrication system.
High Oil Pressure Causes Bearing Clearance Problems
Engine oil serves three primary functions: reducing friction, regulating temperature, and suspending contaminants. The oil pressure gauge or sensor can fail, providing false readings that indicate a problem that does not exist.
