The oil pan gasket seals the oil pan to the bottom of the engine.
It is not uncommon for the oil pan gasket to wear out and start leaking oil.
When a gasket is damaged, oil will leak out, past the gasket, and on to the ground.
So, If you see drops of oil under the car, it may be due to a faulty oil pan gasket.
If your Oil Low warning light becomes illuminated or you notice leaking oil, have it inspected immediately.
Making sure that the oil level in your engine stays at the right levels should be a top concern.
There are so many different factors that go into keeping the oil in the engine.
The oil pan is one of the most important elements to keeping your oil where it belongs.
Engine oil pans hold most of the oil in an engine at a given time.
The material the gasket is made of will begin to deteriorate over time due to the high amount of heat. Eventually, the gasket will begin to leak and will create drops of oil under the car.
How Does It All Start
Like most components of a vehicle, the oil pan gasket does not last forever. As you continue to drive your vehicle, the gasket will go through wear and tear. Eventually, it will get to the point where the gasket will not be able to seal the oil any longer.
As a result, oil will begin to leak as it circulates between the engine block and the oil pan. So, You need to recognize the symptoms of this issue so that you can replace the gasket immediately. Otherwise, it could cause major damage to your vehicle.
Obviously, the biggest and most obvious symptom will be oil leaking from underneath your vehicle. The material that the gasket is made of will begin to deteriorate due to the high amount of heat. Eventually, the gasket will begin to leak and will create drops of oil under the car.
Neglecting to fix this issue right away can lead to a low oil level and pressure. That can be dangerous and compromise the functionality of your engine.
If oil is leaking out, it will not have enough oil to lubricate and cool down its components. The engine oil is part of what keeps the engine cool. Along with the coolant, engine oil is used to keep friction and heat down in the engine.
If the oil pan leaks and the oil level drops it can cause the engine to overheat. An overheating engine can cause extensive damage if left unattended.
Another sign you will see when the oil pan gasket is leaking is smoke coming from the engine. This is usually caused by the oil from the oil pan falling on the hot exhaust manifold. Letting this problem persist may also lead to things like the oxygen sensors or various other components becoming damaged.
Low Oil Level
In some cases, the leak that the oil pan gasket has will be very small and nearly undetectable. Usually, for leaks like this the only warning sign that you will have is a lower than normal oil level. The engine warning light should illuminate on your dashboard if you have a lower than normal oil level.
Oil Only Leaks While The Engine Is Running
Fixing an oil pan gasket leak can be a frustrating ordeal. Your oil pan is always going to be the lowest component on your engine. As oil is pumped all through your engine it drains by gravity back to the oil pan. Gravity always takes liquids to the lowest possible place, so that is where your oil pan sits. The oil pan catches and holds all the oil in your engine whether it is running or not.
Consequently, The level at which the oil sits in your oil pan is actually below the gasket. This turns out to be a good thing if you have an oil pan gasket leak. So, Once you turn your vehicle off the oil settles below the gasket and the leak will stop.
This also can make it difficult to identify an oil pan gasket leak. As a result, The only time oil is leaking from the oil pan is while you are driving.
How To Confirm Your Oil Pan Gasket Is The Source Of Your Leak
Always, Start off with a visual inspection
Engine Oil Leaks-Most Common Places To Look:
- Oil Fill Cap
- Oil Filter
- Pan Drain Plug
- Oil Pressure Sensor
- Valve Cover
- Front Crankshaft Main Seal
- Timing Cover Gasket
- Rear Crankshaft Seal
- Engine Oil Cooler Adapter
- Oil Level Sender
- Oil Pan
- Intake Manifold
- Head Gasket
Start by thoroughly cleaning all the oil from your engine using brake clean or a engine degreaser. An oil pan gasket leak can be difficult to identify. So, It is worth making sure that your oil pan gasket is actually where the leak is coming from. There can be evidence of a leak down to your oil pan gasket on the outside of your engine.
Just because you have oil around your oil pan, doesn’t mean your oil pan gasket is leaking. While inspecting your engine, make sure to check for evidence of a leak and oil residue above your oil pan. If you find oil above it, it may just be dripping down from another leak source.
Using A Smoke Machine
Smoke technology is a quick, simple solution for troubleshooting leaks in virtually any closed automotive system. In fact, finding leaks with a smoke machine is as simple as looking for the smoke, exiting the engine. And virtually all automakers agree, a smoke machine is the fastest, easiest and safest way to find leaks.
Using A Fluorescent Leak Dye Detection System
The combination of an ultraviolet (UV) or blue light and fluorescent dyes allows you to find small oil leaks. Add the dye to your oil reservoir and let your engine idle for 10 minutes. With the overhead lights off, shine the fluorescent light over your engine. Glowing areas indicate leaks.
Find Leaks By Applying Air Pressure – The Soapy Water Test. (The same way we used to find leaks in tires)
Another way to find oil leaks is to pressurize the intake manifold with about three lbs. of regulated air. This can be done by attaching a regulator to your shop air hose.
Next, Attach the hose to a vacuum fitting or the PCV valve fitting on the intake manifold. Do not apply too much pressure or you may create new leaks!
With the engine off and air flowing into the manifold, spray soapy water on suspected leaks. Consequently, If you see bubbles, you have found the leak.
An oil leak can indicate a serious issue with a vehicle. So, Being aware of the signs of a leak is an important step in preventing catastrophic engine damage. As oil leaks out and the levels become dangerously low, the engine loses necessary lubrication, which lead to expensive repairs. Thankfully, there are several ways to easily determine if your car has that dreaded leak without breaking the bank.
Your oil deteriorates as it ages, producing sludge and other corrosive substances. In addition, dirt, abrasive particles, metal fragments and byproducts of combustion accumulate in your oil over time. If your oil isn’t changed, these items can cause wear on gaskets and seals, causing them to fail.
So, Again proper maintenance is always at the top of the list for keeping you on the road.
