The most common reasons a 2017 BMW M6 is leaking oil are oil system component failure and leaking engine gaskets.
  • Oil System Components: A worn or damaged oil pump or filter can lead to low oil pressure, resulting in inadequate lubrication and potential engine damage.
  • Engine Gaskets: A worn or damaged engine gasket can lead to oil or coolant leaks, resulting in engine overheating or loss of lubrication.

How much does it cost to fix a 2017 BMW M6 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.

What are the steps to diagnose the oil leak in a 2017 BMW M6?

To effectively diagnose an oil leak in a 2017 BMW M6, start with a thorough visual inspection of the vehicle. Look for any visible signs of oil accumulation under the car, particularly around the engine, oil pan, and other components. This initial step can often reveal the source of the leak. Next, regularly check the oil levels; a significant drop in oil can indicate a leak that needs addressing. Pay special attention to the oil filter and drain plug, ensuring they are securely tightened, as loose fittings can lead to leaks. For a more precise diagnosis, consider adding UV dye to the engine oil and using a UV light to spot any leaks, as the dye will illuminate under the light. If the source remains elusive, performing a pressure test on the oil system can help identify hidden leaks. Additionally, inspect the gaskets and seals, such as the valve cover and oil pan gaskets, which are common culprits for oil leaks. If these steps do not resolve the issue, consulting a professional mechanic is advisable for a comprehensive diagnosis and repair. This systematic approach not only helps in identifying the problem but also ensures that simpler fixes are attempted before moving on to more complex diagnostics.

What are the common causes of oil leaks in a 2017 BMW M6?

When dealing with oil leaks in a 2017 BMW M6, it's essential to understand the common problems that can arise. One of the primary culprits is degraded or damaged gaskets and seals, particularly the valve cover gasket, oil pan gasket, and camshaft seal, which can deteriorate over time and lead to leaks. Additionally, a worn or damaged oil filter housing gasket is frequently responsible for oil escaping from the engine. Another area to inspect is the oil cooler lines and connections, as faulty components here can also result in leaks within the engine compartment. It's crucial to check the oil drain plug and its seal, as issues in this area can cause oil to leak from the oil pan. Lastly, be aware that damage to the oil pan itself, whether from cracks or corrosion, can lead to significant oil loss. Addressing these issues promptly is vital to maintaining the performance and longevity of your BMW M6, and regular inspections can help catch these problems early.

How urgent is it to address the oil leak in my 2017 BMW M6?

Addressing an oil leak in your 2017 BMW M6 is not just a matter of routine maintenance; it is a pressing issue that requires immediate attention. Ignoring an oil leak can lead to a significant drop in oil levels, which compromises engine lubrication and can result in severe engine damage over time. Additionally, a leaking oil system can cause the engine to overheat, leading to catastrophic mechanical failures that could leave you stranded or facing costly repairs. The safety implications are equally concerning, as oil dripping onto hot engine components can create a fire hazard, putting both you and your vehicle at risk. By tackling the oil leak promptly, you not only safeguard your engine's health but also prevent more extensive and expensive repairs down the line. Therefore, if you notice any signs of an oil leak, it is crucial to act swiftly to maintain the performance and longevity of your BMW M6.
