How much does it cost to fix a 2012 Mitsubishi Eclipse 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.

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 Mitsubishi Eclipse?

To effectively diagnose an oil leak in your 2012 Mitsubishi Eclipse, begin by visually inspecting the area beneath your vehicle for any signs of oil pooling or dripping, as this can help you identify the leak's source. Next, check the oil level in your engine; a consistently low level may indicate a leak that needs attention. Pay close attention to the oil filter and drain plug, ensuring they are secure and free from damage, as these are common culprits for leaks. Additionally, examine the gaskets and seals, such as the valve cover and oil pan gaskets, since wear and tear can lead to oil escaping. If the source remains elusive, consider using UV dye in the engine oil, which can illuminate leaks under a UV light after running the engine. For a more thorough investigation, a pressure test of the oil system can reveal hidden leaks by pressurizing the system and observing any oil escape points. If these methods do not yield results or if you feel uncertain about the process, consulting a professional mechanic is advisable for a comprehensive diagnosis and repair recommendations. By following this structured approach, you can efficiently identify and address the oil leak in your Mitsubishi Eclipse.

What are the common causes of oil leaks in a 2012 Mitsubishi Eclipse?

When dealing with oil leaks in a 2012 Mitsubishi Eclipse, it's crucial to understand the common culprits that may be at play. One frequent issue is a worn or damaged oil pan gasket, which can deteriorate over time and lead to significant leaks. Additionally, the valve cover gasket is another common source of leaks, as it can also wear out and allow oil to escape from the top of the engine. Another area to inspect is the oil filter housing gasket; if this component fails, it can result in oil leaking near the oil filter, creating a mess and potential engine damage. Furthermore, the rear main seal, located at the back of the engine, is prone to leaks as it ages, while oil cooler seals can also wear out, leading to leaks around the oil cooler. Addressing these issues promptly is essential for maintaining the health of your vehicle, and regular inspections can help catch these problems early, allowing for DIY repairs before they escalate into more significant concerns.

How urgent is it to address the oil leak in my 2012 Mitsubishi Eclipse?

Addressing an oil leak in your 2012 Mitsubishi Eclipse is not just a matter of routine maintenance; it is a pressing issue that requires immediate attention. An oil leak can significantly reduce oil levels, leading to inadequate lubrication of engine components, which increases the risk of severe engine damage. Furthermore, neglecting this problem can result in engine overheating, potentially causing catastrophic mechanical failures that could leave you stranded or necessitate costly repairs. Additionally, the safety implications cannot be overlooked; oil that drips onto hot engine parts poses a fire hazard, endangering both you and your vehicle. Therefore, it is crucial to act swiftly and resolve any oil leaks to safeguard your engine's health and ensure your safety on the road.
