Car Tune UpMany drivers simply shrug off an oil leak in their automobiles, although it can actually be a sign of a more severe problem if not properly addressed. Often, an oil leak is only noticed when there is either a large spot on the driveway or a driver notices the oil light turning on. It is important to have the cause of any leaks identified and remedied so that existing problems do not worsen.

Oil Filter
One common cause of leaking oil is an oil filter that is loose or has been improperly aligned. Many vehicles may simply have a worn-out oil filter that needs to be replaced. It is important to ensure that, along with every oil change, the oil filter is also being replaced. Ensure that your mechanic has properly installed your oil filter.

Drain Plug
The oil pan is located on the underside of a vehicle and a common oil leak is located around the drain plug, which is on the very bottom of the oil pan. The drain plug could be improperly threaded or simply loose.  Or, it is could have simply decayed with time and be in need of replacing.

Oil Filler Cap
Another common site of leaking oil is the oil filler cap which covers the hole in the engine where oil is added. Pressure from the engine can put stress on the oil filler cap, causing oil to leak out, if the cap is broken, loose, or even missing.

Valve Cover Gasket
The most common site of leaking oil in automobiles is the valve cover gasket. It is a seal that prevents leakage and joins the valve cover and the engine. Oil is drawn to the top of the engine from the bottom and collects beneath the valve cover, slowly draining back into the engine via drainage holes. The valve cover gasket prevents the oil from leaking all over the engine and onto the ground. If a vehicle’s oil is not changed often enough sludge develops, clogging the drainage holes and placing a lot of pressure on the valve cover gasket. When the gasket is unable to function properly, oil leaks often occur.
