Your engine oil is essential to the life of your vehicle, and one of the last things you want is an oil leak. Not only can oil leaks lead to low oil pressure, but they can also cause unnecessary wear and tear to your engine. If you&#;re noticing common signs of an oil leak, such as dark puddles under your vehicle or an illuminated dashboard oil light, don&#;t wait to fix the issue. Learn what causes engine oil leaks and how to resolve the problem with this guide.

The filter is one of the most common causes of an oil leak. Ideally, the oil filter should be replaced with every oil change. If you change your oil at home, you may forget this important step or the new filter may not be installed properly. If you&#;re wondering how to find an oil leak, start by checking the oil filter&#;s seal. Make sure the oil filter is tight and ensure that the gasket or o-ring is not protruding out of place.
Gaskets act as seals between different vehicle components, so it&#;s no surprise they offer plenty of possible engine oil leak locations. Your engine has many gaskets, and many of them can wear out over time and lead to an oil leak. If you suspect your vehicle is leaking oil, either internally or externally, one of the following gaskets could be to blame:
Without the right knowledge and experience, locating a damaged or worn gasket can be difficult. Be sure to have a Tires Plus professional take a look to diagnose the issue.
In addition to gaskets, your vehicle also has multiple seals that keep the oil where it should be&#;inside your engine! If you notice an oil leak, a crankshaft or camshaft seal could be the cause.
Crankshaft seals can be found at both ends of the crankshaft. If these seals dry out, crack, or get damaged, they can lead to leaks. A small leak usually results in oil on the underside of your engine, and a larger leak could cause an oil drip at the front or rear of your engine.
Engines with timing belts can experience camshaft seal leaks. These leaks can lead to oil pooling under your vehicle or smoke coming from the engine. Both camshaft seal and crankshaft seal leaks can be hard to diagnose at home, so you&#;ll want to take your vehicle to a professional for diagnostics and repairs.
During every oil change, the drain plug is removed to empty the old oil from your engine. Since this component is messed with so often, it can become loose. Many drain plugs also have a gasket or seal that eventually wears out. Luckily, this is a super easy fix. If the plug wasn&#;t tightened all the way after your last oil change, all you need to do is tighten it. If that still doesn&#;t work, you&#;ll just have to swap it out with a new one.
If you have a major oil leak that&#;s leaving big puddles under your vehicle, it might be the oil pan. Because the oil pan sits beneath your vehicle, it&#;s more susceptible to damage from road debris and large rocks. A cracked or punctured oil pan will leave holes for the oil to escape, and a dented pan can compromise the seal the drain plug creates.
Routine maintenance &#; and the inspections that coincide &#; are key to identifying oil leaks early. Make sure you stay on top of oil changes (don&#;t forget to change the filter!), and be cautious when driving over road debris or big rocks while off-roading.
In some cases, if a gasket or seal has just started leaking from an older, high mileage engine, certain engine oils are specifically formulated to help rejuvenate some types of gaskets and seals. Ask your Tires Plus representative for more information if this applies to you.

Have you ever found yourself facing a low engine oil warning shortly after topping up? Maybe you&#;ve found oil leak stains spotting the ground where your car was parked. Pay close attention, because these are signs of car oil leak, and trying to drive a vehicle with a major oil leak &#; even a short distance &#; can do massive damage to your engine. Driving with low engine oil could mean depriving your vehicle of lubrication and stopping heat from circulating, leading to major drops in engine performance.
The good news is that most car oil leaks start small. In fact, a puddle between 1 to 2 inches in diameter, or what&#;s referred to as &#;seepage,&#; usually don&#;t represent an immediate threat to your engine.
Here are a few of the reasons your engine might be leaking oil unexpectedly.

Cracked Gasket: The Core Culprit in Most Engine Oil Leaks
More often than not, a sudden oil leak after oil change is caused by a malformed or cracked gasket. Gaskets are usually made of urethane or rubber, and they can harden over time. This can cause them to crack when they are exposed to sudden impact or extreme temperature changes, like the transition from a harsh winter to a hot summer. Since the gasket can no longer seal in the oil properly, it drips and spills out underneath your car &#; depleting engine oil levels slowly over time and leaving you with those shining puddles on the asphalt.
After examining your valves, the gasket is the first place to look for trouble when you suspect an oil leak.
A Faulty Oil Filter or Oil Filter Leakage
Another place to look when finding the source of an oil leak is the oil filter. Worn metal powders and other small particles often get mixed into the engine oil over time. It&#;s the oil filter&#;s job to parse these out and keep your engine oil supply free of contaminants. But when the oil filter is installed too loosely, it can start to cause leaks and allow oil to flow in places it&#;s not meant to be.
If your oil filter is leaking, try tightening it using your hands and a dry towel. If the oil filter still leaks, you may need to go deeper by removing the oil in your vehicle, replacing the oil filter, and then adding in new oil &#; essentially giving your vehicle an oil and a filter change all at once. Spraying lubricant around the base of the oil filter may tell you whether there any tiny leaks in the seal. If you do check the drain plug and oil filter but you don&#;t find any leaks, you may need to remove the oil pan and check the gasket.
Driving in Severe Conditions
Driving in highly saline places like along the coast of an ocean can also lead to more oil leaks than driving further inland. The salty conditions corrode the metal parts of your engine faster than usual, which can decrease the durability of your vehicle&#;s parts and lead to more frequent leaks. Of course, going to the beach once or twice during summer won&#;t cause you any problems. But if you happen to live in a coastal area, park near the beach, or drive seaside roads frequently, it may be beneficial to pay closer attention to what&#;s going on under your car.
Long drives in cold areas or excessive acceleration at cold temperatures can also put additional strain on the gasket and other systems, eventually leading to reduced durability and potentially resulting in engine oil leaks.
What to Do if You Find an Oil Leak
If you find signs of an oil leak, the best thing you can do is find the culprit right away. After discovering the faulty part, you should have it replaced or repaired immediately. In extreme situations you may consider using an engine oil stop, but this is only a temporary measure and won&#;t resolve the root cause of the problem.
Since small leaks can be tough to find, regular engine inspection and maintenance is your best way to prevent surprises and stop minor car oil leaks from becoming major ones. Checking your engine oil levels through the engine oil gauge and inspecting the bottom of your car when changing your engine oil can also go a long way to helping you avoid leaks and keep your vehicle running safely for longer.
