Mitsubishi Outlander Valve Cover Gasket

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:

Oil leak

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.

  • Tips to Keep Your Mitsubishi Outlander Valve Cover Gasket in Good Condition 27 February 2013

    The Mitsubishi Outlander valve cover gasket prevents the oil inside the engine from leaking. Because of the constant high pressure and temperature, it will gradually show signs of wearing down and may soon crack or get damaged. To make sure that the valve cover of your car works at optimum level and reaches its maximum service life, here are some maintenance tips you can follow:


    Clean the valve cover's surface thoroughly.


    If you already need to replace the valve cover gasket of your car's engine, then what you need to do is to remove the oil that has hardened around the valve cover. Aside from that, you should also remove the rubber sealant from the old gasket using a plastic tool. Keep in mind that you shouldn't use a metal tool to scrape off the sealant because it can damage the valve cover's surface and cause chips or cracks.


    Place the valve cover gasket in the right position.


    If you need to inspect your Mitsubishi Outlander valve cover gasket, remember to place it back correctly. There are holes on the gasket that should match the holes on the valve's surface. Aside from that, you should also place the correct side of the gasket that has the adhesive. As an added tip, you should tighten the bolts with the correct amount of torque. Otherwise, too much pressure may lead to damage on the valve cover and its gasket.


    Apply silicone only when needed.


    Not all valve cover gaskets require silicone sealant. It should be applied only on areas specified on the valve cover gasket instructions. In addition, silicone sealant should be used as reinforcement for the gasket and must be applied only when necessary. You should follow the instructions at the back of the silicone tube to determine the proper way of using it.


    Know the right type of engine oil for your car.


    The kind of oil you use for your car is important especially if your vehicle is already high on mileage. The viscosity of oil on older cars generally goes up as the car starts to age. If you've been using 5w-30 oil on your vehicle since you started driving it, then you might want to consider switching to a 10w-30. The viscosity in this type of oil is heavier, and the potential for leak through the valve cover gasket is lower.
