Common Oil Leaks on BMWs
by Erin PochmanEngine oil never goes anywhere or gets used up. Therefore, it is important to check the oil in your BMW regularly, as low levels can signify leaks. If all oil is lost, the damage to a BMW engine will be extensive and costly and may even require a new engine. According to AutohauzAZ, engine oil is dark or honey-colored and greasy. Signs of leaking oil are a burning smell or the presence of wet spots and/or drips underneath the engine and/or car.
Valve Cover Gasket

Leaks from the valve cover gasket are common in many BMW engines. Valve covers sit at the top of the engine to protect the valves and rocker arms. The covers are bolted to the engine and sealed by a cork or rubber gasket. Leaks or seeps can occur even with a new valve cover, but are more common on older cars. According to RepairPal, valve cover gasket leaks are common after 60,000 miles. Applying sealant can sometimes fix the problem, but it is best to check with a certified mechanic.
