Oil leaks are the most common automobile problems, but they are easy to solve by identifying their cause. One of the culprits is your oil filter housing cap where a gasket is keeping it leak-free and a cap is covering it from the elements. Your oil filter housing cap is supposed to keep your oil from spurting out, but it can crack or wear over time. You would know if this is the problematic part by tracing where the leak is. If indeed you have a broken cap, get a direct-fit replacement before the problem gets worse. Doing so will keep your engine parts lubricated all the time and restore the efficient performance of your oiling system.
