Your engine oil is crucial to keeping your vehicle running smoothly, but when an oil leak happens, it can lead to major problems. Not only do oil leaks create a mess, but they can also cause your engine to suffer from low oil pressure and increase wear and tear on its components. If you've noticed dark puddles under your car or that pesky oil light on your dashboard, it’s time to act fast. Here's a guide to help you understand what causes engine oil leaks and how to fix them.
1. Leaking Oil Filter
One of the most common culprits behind an oil leak is a leaking oil filter. Every time you change your oil, the filter should be swapped out too. If it’s not installed properly or if the filter gasket is misaligned, you might start to notice leaks. If you change your own oil, double-check that the oil filter is properly sealed and tightened. If not, a quick fix can save you from losing too much oil or causing damage.
2. Worn Gaskets
Gaskets serve as seals between different components of your engine, and they can wear out over time. Some of the most likely gaskets to cause oil leaks are the valve cover gasket, cylinder head gasket, and oil pan gasket. If you suspect a gasket is leaking, it’s best to get it looked at by a professional. Gasket leaks can happen internally or externally, making them harder to diagnose at home.
3. Worn Seals
Similar to gaskets, your vehicle has multiple seals, such as crankshaft and camshaft seals, that prevent oil from escaping. If they become dry, cracked, or damaged, oil can leak out. Crankshaft seal leaks often result in oil pooling on the underside of your engine, while camshaft seal leaks might lead to oil under the car or smoke coming from the engine. These seals can be tricky to access and repair, so a professional mechanic will be able to diagnose and replace them for you.
4. Loose Drain Plug
After every oil change, the drain plug at the bottom of your engine needs to be properly tightened. If it’s loose, oil can leak from it. Fortunately, this is an easy fix – just tighten it. If that doesn’t stop the leak, the drain plug gasket may need replacing.
5. Damaged Oil Pan
The oil pan sits low under your car, making it vulnerable to damage from road debris or off-roading. A cracked or punctured oil pan can cause major leaks, while a dented pan can mess with the seal of your drain plug. If you suspect your oil pan is damaged, it’s important to have it inspected and replaced if necessary.
How to Prevent Oil Leaks
Routine maintenance is the best way to avoid oil leaks. Regularly scheduled oil changes and inspections will help catch leaks early before they become bigger problems. Be mindful of road debris and avoid off-roading on rough terrain to protect your oil pan from damage. Additionally, if you have an older engine, certain oils are designed to rejuvenate gaskets and seals, preventing leaks before they start.
