The oil pan serves as one of the essential components that safeguard your engine oil to where it belongs. Knowing oil pan gasket leak symptoms will help you well. The oil Pan is located at the bottom of your car, and it is sealed with an oil pan gasket.

What is an oil pan gasket?

In general, gaskets are mainly used as cushioning and sealing agents, placed in between two components and fastened with bolts or nuts. So, what is the main work of an oil pan gasket? According to the above definition, the main purpose of the oil pan is to safeguard oil from dripping out of where it’s supposed to be.

The types of oil pan gasket in your vehicle will depend solely on the material used in manufacturing your oil pan. Aluminum pans, for example, use some form of liquid silicone, while a pressed steel pan goes with a formed rubber gasket. While the engine is idling or running, oil travels through the engine oil galleries to lubricate all the components within the engine. The seal the gasket forms accepts contraction and expansion from the heat produced by the engine. The cushion, the gasket, forms a fight against damage from the engine.

Oil pan gasket leak symptoms

Let’s quickly look at the oil gasket leak symptoms so you can easily detect when the oil pan gasket leaks.

Smoking issues: One of the most noticeable symptoms that will pop up when the oil pan gasket is long gone is smoke from your engine. The smoke usually comes up when the dripping oil drops on the exhaust pipes or manifold. Not giving adequate attention to this issue may cause other problems like damaging your oxygen sensors and other car components due to being soaked for long in oil.

Engine Overheating: Engine oil is one of the components that keep the engine running at standard temperature. With the engine coolant, the engine oil reduces excess heat and friction in the engine. If your engine oil drops far below the average level due to an oil leak, it will cause the car engine to overheat. An Overheating engine could cause severe damage to other engine components if not given much attention.

Oil Puddles under your car: If you start noticing the car leaking oil when parked, it could be the oil dripping from a faulty engine oil pan gasket. Over time, the rubber material used in manufacturing the gasket will begin to deteriorate due to the high engine temperature that the gasket is exposed to. Eventually, the gasket will get weak or damaged, and you’ll start noticing a drop of oil under your car. Failure to take this as a top concern and fix the issue once you notice it will lead to low oil pressure and oil pump failure, which will profoundly affect your car’s smooth running.

Low Oil level: In some cases, at first, the oil pan gasket leak will start dropping a small amount of oil, which you’ll hardly detect. Usually, when driving with an oil pan gasket leak like this, the only symptom you’ll notice is a low oil level. This can also display a check light on your dashboard. You should also bear in mind that some other issues could cause the check light to pop up.
