Oil Pan Gasket Leak

An oil pan gasket leak will put your vehicle's engine in great danger if left unattended. We know this because the oil pan gasket is an important component and works hand-in-hand with your vehicle's engine's oil circulation. The oil pan gasket sits between the engine block and the oil pan.

Symptoms of oil pan gasket leak

Oil pan gasket leak[/caption]We know that the oil pan gasket functions as a seal between the engine block and your car's engine's oil pan. The gasket helps keep the oil in place while it circulates from the oil pan into the engine block and then returns. An absence of the oil pan gasket will mean leakage of oil will be preponderant.

Furthermore, this will mean an improper circulation of oil from the oil pan to the engine.As we all know, the oil in a car's engine is as important as blood in a human body. Oil helps to lubricate the moving parts of the vehicle's engine.

The absence of oil in an engine will lead to great friction among the moving part. If continued, it will over time lead to the engine's overheating and, eventually, an engine failure.Therefore, this is why components of an engine that work with oil and its adequate circulation must not be taken lightly.

However, the oil pan is one of the most common places where leaks in an engine occur. The oil pan sits at the bottom of the engine block and serves as a reservoir for the oil.

The oil from the oil pan gains motion when the oil pump pumps oil into the engine pathways under pressure.Failure to detect a leak from the oil pan will make your engine run on low oil, and if it persists, severe damage will be imminent.

What are the causes of an Oil Pan Leak?

As earlier described, the oil in a car's engine can leak. However, the oil pan region is often the most commonplace to have such leaks. The oil pan leak is often caused by two main factors: Impact damage or a worn-out gasket.

Oil pan leak caused by Impact damage

Your vehicle's oil pan is susceptible to leak because of its location at the bottom f the engine block. The impact of bad or bumpy roads will largely affect it, and an impact sustained during an accident.Whether from accidents, or bad road networks, the oil pan's safety should be paramount for a good driver. Drive safely and carefully on bumpy roads.

The worn-out oil pan gasket

Unlike the first damage caused by impact, the wearing out of an oil pan gasket isn't a result of bad driving. Most times, the oil pan gasket wears over time and is simply a direct function of usage.When the oil pan gasket wears, leaks become inevitable, and the gasket that formerly stood as a seal has lost its ability to seal.

This scenario is ideal because the gasket is pretty much a thin sandwich layer sitting between the engine block and the oil pan. When this sandwich gasket layer wears, an unwanted opening pops up, and oil will spill as the engine runs.

5 symptoms of an oil pan gasket leak

What are the symptoms of an oil pan gasket leak?[/caption]It should not be a surprise to us when we experience a bad or failing oil pan gasket. Just as we have described, this gasket is often susceptible to wear and tear. This wear happens over time; we only begin to notice it when the wear gets to a level that affects the gasket's functionality. We know that the oil pan gasket functions as a seal between the engine block and the oil pan.

This seal prevents oil from spilling out at this connecting point when oil migrates into the oil pathways.Symptoms of an oil pan gasket leak are essential and must be known by every driver, especially since we know that the engine's health is paramount to us.Let's look at the major symptoms you will find associated with an oil pan gasket leak.

Oil underneath your car

You would often find a small pond of oil underneath your car's engine on the floor.You can easily see this oil after parking your car for a while. To observe this symptom, you can easily bend over in front of your car to see if you will find any trace of oil on the floor.

You can also probe further to be sure this is an oil pan gasket leak or some other engine component leak.

Decreased oil level

Dipstick oil level[/caption]One significant symptom to look out for is a decrease in your oil level to enhance your leak search further. To do this, you can use a dipstick to check the oil level of your engine's oil.If the oil is low, then you might have a leak present. Ideally, you will have to do a quick search around your car to see any oil trace.

Furthermore, you should also take a look at your oil pan gasket or have a mechanic look at it for you to identify the source of the problem. Your gasket may either be damaged or worn out. If either is the case, you will need to replace it quickly to avoid further damage to other engine parts.

Check Engine Light on your dashboard

Although it may have other functions, this light can also serve as a good indicator or symptom to look out for in the occurrence of an oil leak.In some newer car models, there is a portion or different indicator for the oil light. This light also can come in handy. Once this light pops on, we advise that you park your car and investigate the problem properly before driving further.

Engine overheat

We know from this article's trend that one of the main functions of the oil pan is to move towards the engine's moving parts and lubricate them.However, when the oil pan gasket leaks, a sufficient oil amount will not adequately get to all the engine's moving parts. This shortage of oil means friction among these moving parts will become inevitable.

When this friction occurs, heat, which is a close associate with friction, is generated, and thus, the overall engine's temperature goes up and begins to overheat. Once you notice that the oil pan gasket leak is directly associated with this occurrence, the wise line of action will change the gasket. If your engine continues to run, overheating or a failed gasket will become the smallest problem to you in a very short time.

Smoke from your Engine

Smoke from engine

Smoke from engine[/caption]When oil spills because of the leaky gasket, bluish smoke generates from your engine. This smoke either emits from your exhaust pipe or comes out from the top of the engine itself.This scenario happens because the oil leaked into the exhaust manifold, which is usually hot when the engine is running.

The contact between the oil and the exhaust manifold brings about this rather disturbing smoke.Therefore, do not allow this leak to persist as a continuation of this leak will severely damage some electrical sensors in your car. This damage will happen if the oil eventually leaks onto these sensors.

How do I fix my oil pan gasket leak?

An oil pan gasket leak is cured by replacing your oil pan gasket or the oil pan entirely. However, there are other ways to handle a leak on your oil pan without going through the rigor of changing or replacing the entire system.

Your Drain plug vs. Oil pan leak
