Why does the oil can light come on and then disappear after starting?
1 Answers
Car oil can light comes on and then disappears due to insufficient engine oil level or excessively high engine temperature thinning the oil. Below is relevant information: 1. Specific reasons: Oil pump components damaged or excessive clearance caused by wear/assembly issues; Improper clearance between crankshaft and bearings; Oil filter or suction screen clogged; Return valve damaged or malfunctioning; Incorrect oil selection; Oil leakage or blockage in oil lines. 2. Precautions: Only normal oil pressure can ensure oil delivery to all engine friction surfaces. Both excessively high and low pressure will affect engine operation and may damage components. When the oil warning light activates, immediately shut down the engine to identify the cause. Only resume operation after troubleshooting.
