Mitsubishi Outlander Valve Cover Gasket: Three Most Common Problems
The valve cover gasket of your Mitsubishi Outlander was specifically designed to withstand the pressure inside the engine and prevent oil from leaking. However, it will eventually wear down in time and may crack or break due to the high temperature and pressure. When you already notice the presence of oil on some parts of the engine or underneath your car, you should do some troubleshooting immediately because this can lead to a serious car problem. Here are some of the common issues you might encounter:
An oil leak could be a result of a cracked or damaged valve cover gasket. It is probably the most obvious of all symptoms because you will notice oil on the surface of the valve cover or drops or a puddle of oil underneath your car when it's parked and turned off. The only way to prevent this problem from worsening is by replacing the valve cover as soon as possible because the engine's oil level will continue decrease.
Smoke coming from engine
Aside from leaking oil, another symptom is the presence of smoke coming from under your vehicle's hood. This happens when the heat from the engine burns the oil that leaked from the faulty valve cover gasket. As soon as you notice that there's smoke coming from the hood of your car, you should pull over to the nearest and safest area and check if the problem caused by overheating or a broken valve cover gasket.
Slipping accessory belt
Another symptom of a faulty valve cover gasket is a slipping accessory belt. Take for example your Mitsubishi Outlander's serpentine belt. Although the belt has been designed with teeth that prevent it from slipping, the oil that has leaked from the cracked valve cover gasket can make it snap once it reaches the belt' surface. When the belt snaps or breaks, it will the engine to fail and your car to abruptly stop.
Damage on engine parts
Probably the worst thing that can happen, a cracked valve cover gasket can cause great damage to the various parts of the engine. This will happen if too much oil has leaked from the engine and its parts have lost lubrication. As the parts continue to function, they'll soon produce friction and cause damage to each other. You can prevent this from happening by adding engine additives that can fill the small holes which can stop the leak. However, this is only a temporary remedy, and the best solution is to have the gasket replaced immediately.
