How much does it cost to fix a 2012 INFINITI FX35 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.

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.

What steps should I take to diagnose the oil leak in my 2012 INFINITI FX35?

To effectively diagnose an oil leak in your 2012 INFINITI FX35, begin with a systematic approach that prioritizes simpler checks before delving into more complex diagnostics. Start by locating the leak; inspect the ground beneath your vehicle for any visible oil spots, which can help you identify the general area of the leak. Next, examine the oil pan for cracks or damage, as this is a common source of leaks. Ensure that the oil filter and drain plug are securely tightened, as loose fittings can also lead to oil loss. Pay close attention to the valve cover gasket, which often wears out and can be a significant leak point. Additionally, check the oil cooler and oil pressure sensor for any signs of leakage. If the source remains elusive, consider performing a UV dye test by adding dye to the oil and using a UV light to trace the leak. This method can reveal hidden leaks that are not immediately visible, allowing you to address the issue effectively. By following this structured diagnostic approach, you can pinpoint the source of the oil leak and take the necessary steps to resolve it.

What are the common causes of oil leaks in a 2012 INFINITI FX35?

When dealing with oil leaks in a 2012 INFINITI FX35, it's essential to understand the common culprits that may be at play. One frequent issue is the deterioration of the oil pan gasket, which can wear out over time, leading to leaks. Similarly, valve cover gaskets are prone to wear and can also result in oil seeping out. Another area to inspect is the oil filter housing gasket; if this component fails, it can create a significant leak. Additionally, the rear main seal, located at the back of the engine, is another potential source of oil leaks, as it can develop issues with age. Lastly, the seals around the oil cooler can wear out, contributing to oil leakage. Addressing these problems promptly is crucial to prevent further engine damage and ensure optimal vehicle performance. Regular inspections and maintenance can help you catch these issues early, allowing for effective DIY repairs.

How urgent is it to address the oil leak in my 2012 INFINITI FX35?

Addressing an oil leak in your 2012 INFINITI FX35 is not just a matter of routine maintenance; it is a pressing issue that requires immediate attention. An oil leak can significantly reduce the oil levels in your engine, leading to inadequate lubrication of vital components. This lack of lubrication can cause severe wear and tear, ultimately resulting in costly engine damage. Moreover, neglecting an oil leak can lead to overheating, which poses a serious risk of engine failure and expensive repairs. Additionally, the safety implications cannot be overlooked; oil that drips onto hot engine parts can ignite, creating a fire hazard. Therefore, it is crucial to act swiftly and address any signs of an oil leak to protect both your vehicle's performance and your safety on the road.
