1. Oil Level: Ensure that the engine oil level is adequate. If the oil level is too low, it can lead to insufficient oil pressure and subsequent engine damage.
2. Oil Filter: Check the oil filter to make sure it's not clogged. A clogged oil filter can restrict oil flow and reduce oil pressure.
3. Oil Pressure Sensor: Verify that the oil pressure sensor is functioning correctly. A faulty sensor can provide inaccurate readings or fail to detect low oil pressure.
4. Engine Wear: If the engine has accumulated high mileage or has not been properly maintained, excessive wear on internal components such as bearings, piston rings, or oil pump gears can lead to reduced oil pressure.
5. Oil Pump: If the oil pump is faulty or failing, it may not be able to generate enough pressure to circulate oil throughout the engine. However, diagnosing a faulty oil pump requires further testing and inspection.
6. Knocking Sounds: The knocking sounds you mentioned could be due to several factors, including worn or damaged engine bearings, connecting rod bearings, or piston rings. These issues can occur due to insufficient lubrication, excessive wear, or other mechanical problems.
It's recommended that you have your vehicle inspected by a qualified mechanic or technician. They can perform a thorough diagnosis, including oil pressure tests, engine noise analysis, and further inspections as necessary. By identifying the exact cause of the low oil pressure and knocking sounds, the appropriate repairs or maintenance can be carried out to ensure the proper functioning of your Park Avenue.
