The cylinder head gasket is one of the most critical sealing applications used in your engine. It's so important that every head gasket used in your car must have the same strength requirement as any other components found in the engine combustion chamber. This gasket's main function is to ensure maximum compression in the engine cylinder for excellent fuel combustion. The only problem is that high compression rates tend to destroy cylinder head gaskets over time. When this happens, you should immediately invest in a Cylinder Head Gasket Set. The right gasket set should contain all the units you need to replace your old stock head gaskets. In finding the right head gasket set, it is recommended to go for a set that has the same specs as your original gasket. That way, the gaskets in the set will fit perfectly between your cylinder head and engine block. Right-sized gaskets should stop coolant and oil leaks, while maximizing the compression rate in your engine cylinders. They also won't require resizing or modifications when it comes to installing these gaskets. You should also use gaskets that are manufactured from materials that offer superb sealing. Great gasket materials include rubber, MLS, and copper. Lastly, when buying a Cylinder Head Gasket Set, consider getting a set that comes with a warranty. That way, you can easily contact the manufacturer in case you have problems with the product.

Picking out a Cylinder Head Gasket for your Ride

In the huge mechanical wonder that is the engine, small parts like the cylinder head gasket often go unnoticed-until they stop working. Gaskets seal in all the hot gases produced during combustion and keep the process safe and efficient. Any leak can have serious effects on the engine components and may cause total engine breakdown. So if there are noticeable signs of cylinder head gasket failure, you'd better replace it as soon as possible. There are some things to take into account before you shell out some bucks for a replacement unit.

Product fit

Of course, it's best to get a gasket that fits your engine's specifications to be sure that it will work well. Based on product fit, most head gaskets are offered as:

  • OE replacement

If you're looking for gaskets that are as durable as or stronger than your stock, go for OE-replacement units. Why? It's because they are usually made to meet or exceed the standards set by the crash institute for original parts. But even if their fit and quality are as good as original components, they don't wear the label or the logo of the car manufacturer.

  • Direct fit

Direct-fit gaskets are designed to bolt on directly to your vehicle without a need for welding or any modification. These units are also made to fit specific vehicle models.

Types of gaskets

Another factor you should take into consideration is the gasket's construction, which affects not just durability, but its cost as well.

  • Sheet gaskets

These mass-production gaskets are made out of asbestos or fibrous graphite. They come cheaper compared to other types, but they are less durable and are more prone to cracks and breakage when placed under extreme thermal pressure.

  • Solid material gaskets

Made out of sturdy metals, these gaskets ensure better quality, but are priced reasonably. Since they can withstand high pressures and temperatures, solid-material gaskets are commonly used in automotive applications.

When assembled, cylinder head gaskets become very important components of the engine structure, so make sure that the units you'll get can hold up to the dynamic and thermal forces put out by the cylinder head and the engine block.

Cylinder Head Gasket Replacement: Removing the Old Gasket and Installing a New One in Place

The cylinder head gasket is compressed between the engine block and the cylinder head to seal the internal combustion process and keep coolant and oil from mixing together as they move from the engine block to the cylinder head. When the head gasket fails, you'll notice loss of engine compression, coolant, and oil. You'll also observe white-colored exhaust emitting from the tailpipe or a thick creamy fluid in the radiator or oil reservoir. It's a good thing that replacement head gaskets come very cheap; it is the replacement process that will cost you a lot, so you'd better do it yourself. Removing the old and setting up the new head gasket means doing a major operation in the engine's head, but it can be achieved as long as you have the right tools and detailed instructions.

Difficulty level: Difficult

What you'll need:

  • Owner's manual
  • Socket set
  • Replacement head gasket
  • Head-gasket sealant
  • Torque wrench
  • Head bolts
  • Wrench set
  • Screwdriver set
  • Gasket scraper
  • Clean rag

Step 1: Raise your vehicle up on a hoist. Make sure that the arms of the hoist rest underneath strong, load-bearing parts of the vehicle. For your safety, remove the battery and drain the coolant out of the vehicle.

Step 2: Remove the parts that get in your way to the head gasket, including exhaust pipes, air intake, filtering system, air compressor, head cover, and many others. Consult your car repair manual for specifics. Disengage and remove any attachment connected to the alternator. Detach the valve cover and its associated parts. Take off all timing components as well as the head bolts.

Step 3: Remove the old head gasket and check the engine head and block for warping, cracks, and any type of damage. Don't proceed with your replacement unless you're sure that these two parts meet smoothly. If they are in good condition, proceed by cleaning the area where the old gasket sits. Be careful not to scratch or remove metal from either part. Clean also the bolt holes and the bolts that secure the cylinder head to the block.

Step 4: Fit the new gasket onto the block. When specified by the manufacturer, apply gasket sealant, but only use the directed amount in the specific spots and parts. With the new cylinder head gasket in place, install the head onto the block, making sure everything is perfectly lined up. With a torque wrench and new bolts, tighten the head onto the block.

Step 5: Reinstall other engine parts that you've removed. Test and adjust the valve components to ensure correct timing. Do a final oil and coolant change to get rid of impurities.

Since it involves many steps, this task will take up five hours or more. The process and tools you'll need will depend on the type and size of your engine.
