Typically, a cracked or punctured oil pan will result in a significant leak, leaving big puddles of oil under your vehicle. ![]() Since the oil pan sits underneath your vehicle, it can easily get damaged due to road debris, accidents, or hitting a speed bump. In contrast, over-tightening the oil drain plug could damage the threads, eventually resulting in an oil leak. In such a scenario, the oil drain plug may come undone while driving, resulting in an oil leak. While a loose oil drain plug is a common reason for an engine oil leak, it’s only likely to happen if you’ve fastened it by hand. Pro tip: Replace your oil filter roughly every six months or after 5,000 to 10,000 kilometers. Moreover, since oil filters trap contaminants, your oil filter can get blocked with debris, resulting in an engine oil leak. So, check if the oil filter is loose or displaced, especially if you’ve noticed an oil leak after a recent oil change.

Like the valve cover gasket and timing cover gasket, your vehicle also comprises several oil seals, like the crankshaft and camshaft seal, that keeps engine oil from spilling.Įventually, these seals dry out, crack, or get damaged, causing a motor oil leak.īut here’s the thing: diagnosing a crankshaft or camshaft seal leak is tricky, so it’s best to consult a professional. Over time, the valve cover gasket, cylinder head gasket, etc., undergo wear and tear due to friction, load and compression, oil pressure, and high temperatures.Ĭompromised gaskets could result in an engine oil (motor oil) leak. ![]() Gaskets (mechanical seals) fill the space between two or more mating surfaces, preventing an oil leak. Here’s a comprehensive list of the most common causes: 1.
