How much does it cost to fix a Chevrolet SS is leaking oil?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

Oil pans don't wear out or break like other parts, they generally only need to be replaced because of external damage from an accident or an improperly tightened drain plug. The main symptom you will experience is an oil leak underneath the engine of your car. The oil that leaks from a damaged oil pan will range from dark brown to dark black. If the leak is large enough or occurs for long enough the oil level will be low enough to turn the oil pressure or low oil level warning light on.

An oil leak may be noted on the ground where the vehicle is parked. However, many vehicles have plastic trays underneath the engine that may catch leaking oil and conceal the leak. In such cases, a low oil level, a burning oil smell, or even smoke from oil burning in the engine bay may be noted.

A bad oil level sensor may cause a false reading of the engine oil level. The oil level warning light may illuminate even when the oil level (checked manually) is within an acceptable range. The warning light may also come on and off intermittently if the sensor is faulty. An error code may be sent to the PCM and a check engine light may come on the dashboard as well if the sensor is bad.

The engine oil pressure warning light will come on if the engine oil pressure is low, or if the oil pressure sensor is faulty. In either case, engine power may be reduced significantly. The check engine light may also illuminate, and an on-board diagnostic (OBD) trouble code will be stored in the vehicle's computer.

How to Diagnose and Fix Oil Leaks in a Chevrolet SS?

When tackling oil leaks in a Chevrolet SS, it's essential to adopt a systematic diagnostic approach. Start by consulting the service manual to identify the specific steps for diagnosing oil leaks, which will guide you in pinpointing the source of the issue. Begin with the most accessible areas, such as checking the crankshaft position sensors, oil cooler lines, and the oil filter adapter, as these are common culprits. If the leak appears to originate from the engine rear cover assembly, carefully remove it for inspection, paying close attention to any signs of porosity where it meets the engine block. Once you've identified the leak's source, follow the detailed repair or replacement procedures outlined in the service manual. Cleaning the engine with a degreaser can also aid in locating the leak more effectively. By methodically assessing each potential source, you can efficiently diagnose and resolve oil leaks, ensuring your Chevrolet SS remains in optimal condition.

To effectively diagnose the source of the leak, start by consulting the service manual for specific diagnostic steps. Once you identify the leak's origin, such as the engine rear cover assembly, you can proceed with the necessary repairs. It's also wise to check the oil filter and oil plug, as these components can contribute to oil leaks as well.
