What causes low oil pressure in a hot engine after a major overhaul?
1 Answers
Reasons for low oil pressure in a hot engine after a major overhaul: insufficient oil volume, excessively high engine temperature, damaged oil pump components, etc. The following details these causes: Insufficient oil volume: This reduces the oil pump's output or prevents it from pumping oil due to air intake, leading to a drop in oil pressure and triggering the oil warning light. Excessively high engine temperature: This can thin the oil, causing it to leak excessively through component gaps and resulting in decreased oil pressure, which activates the oil warning light. Damaged oil pump components: If the oil pump components are damaged or excessive gaps occur due to wear or assembly issues, the oil pump may fail to deliver oil or provide insufficient oil, causing the oil warning light to illuminate.
