What is the method for oil pressure testing?

[StSilas]

The method for oil pressure testing is: 1. Disconnect the wiring harness plug of the oil pressure sensor and remove the oil pressure sensor; 2. Place the oil pressure gauge in a location where it will not come into contact with rotating or high-temperature engine components; 3. Start the engine and check for oil leaks at the oil pressure gauge connection; 4. Run the engine until it reaches normal operating temperature, then check the oil pressure gauge readings at both idle and 2000 RPM, comparing them with the standard pressure values. The reasons for insufficient oil pressure are: 1. Lack of oil; 2. Clogged oil pump screen; 3. Faulty pressure relief valve; 4. Clogged oil filter; 5. Blockage or cracking in the engine cylinder head or block; 6. Excessive clearance in the engine crankshaft, camshaft, or connecting rod main bearings.
