There are a multitude of components inside the Audi that work together to keep it functioning at its best. From large to small, all of these are equally important to the overall performance and operation of your vehicle.
A somewhat small but significant feature is the oil valve cover. The cover and the corresponding gasket work to keep engine components protected as well as maintaining the proper lubrication levels for the motor. The cover keeps oil from spilling out onto the cylinder heads and other working parts under the hood. While Audi has been committed to making their covers more durable, they can still fall victim to damaging issues.
Signs and Symptoms of Valve Cover Oil Leaks
One of the easiest ways to detect a leak is by visually inspecting the valve cover itself. The cover should be clean and smooth, with no apparent debris on top. Weeping or leaking oil can attract dirt and other forms or debris. This sludge or gunky residue will then rest on top of the valve cover. This buildup is a tell tale sign that there is an issue with the cover.
Another symptom of a leaky valve cover is the smell of burning oil or the appearance of smoke. If the cover becomes cracked or damaged, oil can drip down onto the engine, fuel intake or even the exhaust pipes. As these components heat up, the oil will begin to burn, producing a distinctive odor. This burning may also produce a small yet noticeable amount of smoke. You might also see a puddle of oil under your vehicle. If you become aware of any of these conditions, have your Audi evaluated as soon as possible. In rare instances, this hot oil may interact with the exhaust manifold and result in a fire under the hood.
Low oil levels are always an indication of an oil leak somewhere in your vehicle. A cracked valve cover or damaged gasket may allow a minute amount of oil to seep through. In this scenario, your oil level may drop slowly but it can be the first sign that you have an issue which needs to be resolved. Low engine oil levels can be detrimental to your Audi as improper lubrication leads to overheating.
A motor that overheats may not be able to be repaired, it may need to be replaced. This can be quite costly and inconvenient. Technicians will alert you of low levels during routine maintenance but you should also be aware of your warning lights. If the engine oil alert is present on your dashboard, see immediate assistance.
A sudden change in how your automobile performs can also be a symptom of a faulty valve cover. Leaked oil may travel to the spark plugs, resulting in a misfire of the engine. You may also notice an inability to accelerate as quickly as usual when driving. Rough running engines are suffering from a faulty component, which could be this cover.
Common Causes of Valve Cover Leakage
Vehicles that are driven in certain environments are more prone to suffer an issue with their valve cover. For example, moist and humid climates or salty conditions can accelerate corrosion.
These components are more vulnerable to extreme temperatures due to their composition. Heat and cold can cause the cover to expand or contract. The small shifts in the size and shape of the cover or the gasket can result in serious damage. They can be pinched, cracked or even broken.
