Signs of Valve Cover Oil Leaks in an Audi
If you think you have a valve cover leaking in your Audi, you’ve come to the right place. We’ve compiled a breakdown and explanation of the most common signs that you may have a leak in your valve cover. The leak could be from a seal or from a crack in the valve cover. Both can be determined by a trained technician and can result in one or more of the following signs and symptoms. If you find yourself with one or more of the below problems, contact your trusted Audi specialist right away.
Common Symptoms of a Valve Cover Oil Leak
Oh, the Smell!
The most telltale sign that you have a leaking valve cover is the smell of burning oil. It is one of those smells that you will almost instantly recognize once you have identified the odor. When a valve cover has a leak, the oil is thrown from the engine as it runs. Oil can get all over your entire engine. This often results in the smell of burning oil. If the leaking oil makes its way to the exhaust manifold, a fire can occur.
Where there’s Smoke, There’s a Leak
One visible sign is smoke coming from the engine department. This is the result of the burning oil that was mentioned above. The smoke may not be visible upon first starting the engine. However, as the engine heats up, the motor oil will become thinner and more can escape through the leaking valve cover. Smoking is usually more visible when you stop after your engine has had time to heat up.
Pop the hood and take a close look. If your valve cover is leaking, you will likely see a buildup of dirty, thick oil on the valve cover. In some cases, the underneath side of the hood will also have oil stains that are visible. As the oil escapes, it is thrown against the hood and lands back on the top of the valve cover.
Audis are smooth luxury vehicles. When they start to run rough, it is a sure sign that something is amiss. One of those possibilities is a reduction in the oil pressure caused by a leaking valve cover. In some cases, your Audi may even begin to misfire if oil comes into contact with the spark plugs.
If you check your engine oil to find that you Audi is low, you may have a leaking valve cover. Although you will also have some or all of the above-mentioned signs, a sudden drop in oil level is a clear sign there is a problem.
Causes of a Valve Cover Leak
Over time and with normal use, a valve cover can crack or leak, due to no fault of the driver. In some cases, when an Audi is driven in extreme temperature variances, it can cause fluctuations in the seals of the valve cover, leading to a leak.
Another common cause of a valve cover leak is after an engine has overheated. There are several issues that can cause an engine to overheat. In all instances, you should have your car inspected to ensure that no damage has occurred. One of the components that could be affected is the valve cover.
