The engine is your car's powerhouse. So do you think it'll work well if one of its components is damaged? Naturally, it won't. And even though it might, for sure, you'll find the performance wanting. All engine parts, big and small, need to be regularly and carefully maintained to ensure seamless performance all the time. Even a small part like the Valve Cover Gasket needs to be properly maintained to ensure a long service life for the engine. This gasket's main concern is to keep the well-being of the valve cover. It securely seals the valve cover so that oil leaks will be prevented each time it pools lubricant oil as it goes to the cylinder head's drain back opening. Aside from oil, this gasket also helps prevent the entry of other harmful materials to the valve train. By having a functional and efficient Valve Cover Gasket, one is able to secure the effective function of the valve cover. Installation of a new gasket must be accomplished carefully and accurately. The attachment to the valve cover must be just right-not too tight and not too loose. Any of these two conditions can ruin the gasket's efficiency; consequently, the valve cover itself. If the valve cover's gasket in your car is already worn and torn, don't think twice about replacing it. Replacement parts are very affordable. Getting one won't even dent your budget-especially if you order it from Auto Parts Warehouse, where only the best deals for quality auto parts and accessories are offered. So shop here now!

Tips for Buyers: Guide to the Right Valve Cover Gasket for Your Car

With all the moving parts and flowing fluids inside your car, it's no wonder why there are leaks or seepage under its hood. In order to protect all the other parts of your engine, as well as to decrease fluid wastage, gaskets are there to help. One of these gaskets is the valve cover gasket, which is found between the engine cylinder head and the valve cover. With the different kinds of valve cover gaskets available, which one is best for your car? To help you choose the right valve cover gasket, here's an overview of the different materials used for gaskets:

Silicon rubber valve cover gasket

Silicon rubber gaskets are the most common type of valve cover gaskets on cars today. If your car has been originally fitted with this type of gasket, it's best to stick to the same material once it needs replacing. Valve cover gaskets that are made of silicon are generally reusable and easier to fit. Although the material tends to shrink with age, it's highly durable and less prone to breakage. Silicon rubber gaskets are also perfect for many classic cars. It is easy to remove and replace for adjustment, which allows it to fit most outdated valve covers.

Cork valve cover gaskets

If you're looking for a valve cover gasket with a stronger seal, one that is made of cork would be your best bet. Unlike other materials that merely stop the oil from leaking out, this kind of material can soak up most of it. However, you have to be very careful when handling cork-type valve cover gaskets. They can easily disintegrate when retightening the bolts and if the job is not handled with care it may mean re-doing the installation. Another disadvantage of using cork valve cover gaskets is that they can be difficult to reuse once they are removed. They can dry out and crack out.

Other types of valve cover gasket

Aside from the two major types of valve cover gasket, there are also gaskets made from other materials. One of these materials is laminated cork. Laminated cork is a reinforced version of the cork-type gasket. It makes use of a metal gasket with cork on both sides, which offers a far stronger and more durable gasket. On the other hand, a revamped silicone gasket is also offered in the form of a rubber-coated fiber valve cover gasket. The addition of fiber to the rubber gasket enables it to absorb oil, just like the cork-type gasket, but with the flexibility of silicon rubber. Lastly, the most modern type is the composite gasket. Out of all the types of valve cover gaskets (based on material used), composite gaskets are probably the most durable. They also have the best resistance to heat, which makes them the most expensive as well.

Installing a New Valve Cover Gasket

While airbags and seatbelts are added to your car to ensure your safety, it is also fitted with safety measures that protect it from all its moving parts. These parts are called gaskets. One of the most important gaskets is the valve cover gasket. It protects your engine from oil and water leaks and other fragments. So the next time you find a leak in your engine manifold, here's a step-by-step guide to replacing your valve cover gasket:

Difficulty level: Easy

Things you'll need:

  • Socket wrench
  • Putty knife
  • Screw driver
  • Gasket sealer
  • New valve cover gasket
  • Dry paper towel

Step 1: Once you've lifted your hood, locate your valve cover. Your valve cover is relatively easy to find. It is the part that covers your engine block.

Step 2: Before removing your valve cover, make sure you've unplugged any, and all, of the wires connected to your engine and valves. Unscrew all of the bolts that hold the cover in place. After you've removed all bolts and wires from your engine block, your valve cover should lift right up. In case you can't take it out, pry the lid off by wedging a screwdriver along one of its sides. Work your way carefully around the base and lift it.

Step 3: Now that you've removed your valve cover, you'll see a rubber or cork lining in the edges of your engine block. If you still spot some remaining gasket sealers around your valve cover gasket, scrape it off using a putty knife. Remove your valve cover gasket, making sure no material falls into your valve.

Step 4: Re-apply the gasket sealer around your engine block. It should be about 1/8-inch thick to cover the entire surface. Wipe off any excess sealer and let it set for a few minutes. Wait until it gets slightly tacky before you fit your new gasket. Apply another layer of sealer on top of your newly installed gasket.

Step 5: Reinstall your valve cover once the second layer of sealer has set. Make sure that you've cleaned the insides of your cover before reinstalling it on your engine block. Bolt the nuts and reconnect the wires to secure your cover perfectly.

Step 6: Run your car for a few minutes to test your new valve cover gasket.
