Subaru Oil Leaks | Detection, Diagnosis, and Repairs

Pinpointing the Reasons and the Unique Symptoms of a Subaru Oil Leak

When it comes to driving a car from Subaru, oil leak problems can appear just as easily as with other brand vehicles. Subaru's superior technology can be impressive, but common problems such as the older Subaru head gaskets that keep leaking oil are well-known, and they can account for some of the major instances where oil leaks actually occur. If you want to know how to spot an oil leak and where to look in order to detect it, you will have to adapt your detection techniques to the architecture of the car you're driving. In this case, Subaru has a few unique and highly important areas to look at when checking for leaks.

Reasons for a Common Subaru Oil Leak

As you well know, oil is required to lubricate the engine parts so that your car can run without a hitch. An oil leak is, therefore, a significant problem that can lead to the gradual deterioration of your car and engine, if left unchecked. To detect common oil leaks in your Subaru vehicle, it's important to check the most common areas where they can appear. These should include the rear of the engine, where your PVC baffle plate is located, as well as the piston access plugs and crank seal at the front of the engine, and the spark plug tube seals.

Camshaft seals are some of the most common and easy to access areas. Yet, you still have to take apart the front of the engine to get to them. They are essentially behind the camshaft sprockets, which are situated behind the timing belt cover. With age and gradual deterioration, these seals can end up leaking oil, especially if you own a car that features the older, black seals. The newer, brown ones are considerably more resilient.

Another important reason for Subaru leaks is the valve cover gasket. This gasket can also become deteriorated over time, as the gasket's ability to seal the valve covers can diminish as it shrinks with age and becomes damaged. Sometimes, however, it's simply a matter of valve cover bolts being loosened, so that they end up impairing the seal and allowing oil to flow through.

How to Detect a Subaru Oil Leak

Before considering a Subaru oil change, you will need to know if your car is leaking oil, as well as to detect the source of the leak. Otherwise, replacing and topping up your oil won't help too much. Moreover, an oil change in this case can give you a false sense of safety. Instead of solving the problem, it can ultimately make it worse when your leak becomes worse and you think that you don't need any more oil. The next time you check your oil, it could be too late, and your engine could have already been damaged.

Subaru engines can, of course, be extremely complicated and difficult to take apart. As a result, you will need help and support from a dependable Subaru car mechanic to take everything apart and physically check for concealed leaks. Your Subaru expert will be able to detect whether there is only one or whether there are more sources of a leak, and what's even better, is that they can suggest practical courses of action to deal with them without the need for an exaggerated expense.

Getting your Subaru car in order can be very important in the long run. Instead of trying to fix the problem yourself, it's always better to rely on the expertise, efficiency and experience of your local Subaru specialists, who will detect your Subaru oil leak in time and make sure that it won't bother you anymore.
