If you think your engine is leaking out any kind of fluid like oil or coolant, you better have its gasket checked by a mechanic right away. This way, you can address the problem before it gets worse. Plus, you would have enough time to search for a replacement for your damaged gasket. So always keep your cylinder head gaskets in top form. If you need new ones, better get them immediately.
Cylinder Head Gasket: Just the Facts
When your vehicle's engine overheats, the cylinder head is likely to be damaged as well. And not only that! Excessive engine heat can also cause the cylinder head gasket to become bent and warped. And simple and plain as it may seem, a damaged cylinder head gasket, when damaged can bring more serious problems. Topping the list, your vehicle's engine can suffer compression loss, which can lead to power reduction. Also, exhaust gases will be forced into the cooling system, allowing motor oil to mix with the antifreeze. To prevent the entry of engine oil, coolant and air into the cylinder, make sure that your vehicle's cylinder head gasket is in perfect shape. If you need to replace your stock cylinder head gasket, search no further. CarParts.com can give you the cylinder head gasket that's perfect for your vehicle's engine.

Cylinder Head Gasket: What Every Car Owner Should Know
Your vehicle's engine uses a variety of seals and gaskets to ensure smooth, contaminant-free engine operations. Perhaps the most important sealing application in the engine is the cylinder head gasket set. If your vehicle is equipped with a 6 or 8-cylinder engine, then your vehicle's engine comes with two cylinder head gaskets. The cylinder head gasket acts as a seal between the engine block and the engine's cylinders. By making the engine's cylinders airtight, the cylinder head gasket ensures maximum compression and prevents coolant or engine oil leakage into the cylinders. Cylinder head gaskets are usually designed to hold their own against high amounts of pressure and heat in the engine bay. Overheating, however, could ultimately render the cylinder head gasket set useless.

Even a simple seal can contribute to the smooth operations of the engine. This is proven by your cylinder head gasket. It functions by keeping the pressure from the spark plugs to stay intact in the combustion chamber. In addition, because of your cylinder head gasket, the oil and coolant that passes through the cylinder and the engine will not be mixed. Hence, it must always be well-maintained to avoid engine malfunctioning. So if you need a replacement, do not hesitate to buy a new one. Here are the things that you must look for in purchasing a cylinder head gasket:
Which cylinder head gasket is fit to be used for your vehicle?
You can opt for an original equipment (OE) replacement for your cylinder head gasket. This is because this type is durably made for your driving needs. Thus, you can surely rely on it; however, an OE-replacement cylinder head gasket does not carry the label of your manufacturer.
A direct fit type of cylinder head gasket is also recommended. This one is made to be easily attached on your vehicle without any necessary modification. However, you must make sure that the direct fit cylinder head gasket will surely be compatible with your vehicle.
What are the types of cylinder head gaskets that you must look for?
There are several types of cylinder head gaskets that are appropriate for different types of vehicles. The first one is the solid material gasket. This type is made from durable metals, which has a feature that resists high pressure and temperature. Hence, its life can be extended to a longer period of time. However, it has a higher price compared to other types of cylinder head gaskets.
There is also the sheet gasket, which is less expensive than the first one. It is made of asbestos or stringy graphite. However, it is susceptible to becoming brittle when it undergoes extreme pressure and severe changes in temperature.
Another type is the solid copper gasket, which is a recent design for automotive use. It is durably made from a copper sheet, which is made for direct fit.
The important thing to be considered in looking for the type of cylinder head gasket for your vehicle is its ability to cope up with the pressure and other changes brought by the operations of the engine.
How to Replace Your Cylinder Head Gasket
If there are vital components that you must thank for contributing to the smooth engine operations, your cylinder head gasket would definitely be on the list. It is responsible for sealing the cylinder heads to the engine block so that the pressure will not escape upon the engine. Moreover, it helps to dissipate heat from the continuous operations. However, it can fail over time and once this happens, other engine components can be affected. Hence, you must know how to replace your cylinder head gasket. These procedures can help you to have a successful installation of a new one:
Difficulty level: Moderate
Things you'll need:

Modern internal combustion engines have come a long way since the 1800s. With the advancements came new components that improved how engines perform, even giving them hundreds of additional horsepower. One component that’s often overlooked by some is the cylinder head gasket.
Are you having trouble with your car’s cylinder head gasket? Are you experiencing a leak that traces toward a blown cylinder head gasket? Fret no more. This guide will help you learn more about how you can deal with head gasket leaks, what causes them, and what you’re up against if it gets blown.
What is a cylinder head gasket?
The cylinder head gasket is a type of seal that you can find sandwiched between the two main parts of your engine—the cylinder or engine block and the cylinder head. It is one of your car’s vital gaskets designed to keep all fluids inside your engine from intermixing.
Removing it from installation should reveal a panel with large and small round holes. Each large hole is for the cylinders while the small ones are metering holes for the coolant. Keep in mind that for you to access the head gasket, you’ll have to separate the head cylinder from the engine block first.
What does the cylinder head gasket do?
As mentioned, the cylinder head gasket helps in making sure all fluids running in your engine don’t intermix as this can cause engine problems. However, there is more to the head gasket than segregating these fluids. It also makes sure that the engine has a steady amount of pressure needed to keep these fluids flowing at proper rates. Compression is important for your engine to perform in its optimal state.
Head gaskets are meant to withstand normal heat expansions and pressure from the rubbing of the cylinder head and cylinder block. This does not mean the head gasket is indestructible. Length of service and extreme engine conditions can weaken its structural integrity.
What causes cylinder head gasket failure?
The cylinder head gasket can fail in a number of ways but all failures will always direct to a leak. This leak can either be internal, external, or both. One of the common causes of a blown gasket is pre-ignition. A burst of pressure due to untimed combustion can cause stress to your head gasket, resulting in breakage.
Internal leaks are called compression leaks and depending on where this leak is happening, you may experience misfiring, coolant overheating, blow by, and coolant-oil intermixing. External leaks, on the other hand, will cause your oil or coolant level to drop, which may lead to engine overheating.
Symptoms of a blown cylinder head gasket
Here are some of the inconveniences you may face if your head gasket is in bad shape:
Drop in Coolant or Oil Level
A drop in the coolant or oil level is a clear indication of an exterior leak, meaning your head gasket is blown outside. You may check this by doing an all-around inspection of the engine block.
Bubbles on the Radiator and/or Reservoir Overflow
An internal leak can cause the coolant and oil to mix. On top of that, it can also introduce exhaust gases into the coolant lines. These bubbles are exhaust gases escaping the pool of coolant. Check your radiator cap or reservoir overflow if you suspect a compression leak.
Thick White Smoke from the Exhaust
Thick white smoke may indicate a compression leak where the coolant is leaking into the cylinders. The smoke is created when the coolant touches a hot surface and burns upon contact, causing it to instantly evaporate and get passed onto the exhaust pipes—hence, the thick white smoke.
Increase in Engine Temperature
Engine temperature may start to rise if there’s not enough coolant to absorb the heat. However, it can also happen if the coolant gets contaminated by oil, as this can ruin the cooling system of your car.
Foamy Oil Consistency Under the Oil Filler Cap
Oil should look glossy even if it’s darkening. Foam topping your oil is never a good sign. Water causes this foam formation when it gets mixed with oil as they travel at high rates of speed to and from the engine.
Other Cylinder Head Gasket FAQs
Below are frequently asked questions relating to cylinder head gaskets.
Can a cylinder head gasket be reused
Short answer: No. Don’t fall for the traps you read on forums. A group of users may tell you that they’ve successfully reused their head gaskets. Regardless of whether they’re telling the truth or not, once you put the head gasket in use, it undergoes extreme temperature changes.
Heat causes the gasket to expand. And while you may think it springs back to normal once your engine’s cooled, the expansion has already caused permanent changes with the structure of the head gasket.
What is a cylinder head gasket made of
There’s a wide range of materials used in manufacturing head gaskets, with steel being the most common. Other materials include cork, fiberglass, silicone, rubber, felt, polytetrafluoroethylene, and nitrile.
Does a cylinder head gasket set include camshaft seals
The answer is it depends on the brand. It may also include intake and exhaust manifold gaskets, oil pan gasket, spark plug seals, and more. You just have to look for the description and read what’s included in the set.
How long do cylinder head gaskets last
There’s no definite time as to how long head gaskets last. However, the thing is it’s designed to last as long as your engine’s functional. That is if the engine is running smoothly all the time. That’s the reason why regular maintenance is important.
