What to Look for While Buying The Best Valve Cover Gasket?
The review section that we have included above will not be enough if you want to get the most out of the money. For that, you will also have to keep some crucial factors in mind.
By considering them, you are sure to be able to scrutinize the units efficiently, which will eventually let you make a good purchase decision. The factors that we are talking about are as follows:
First and foremost, you will have to consider compatibility. Even though most of them will have a broad compatibility range, your vehicle might not be included in that broad range.
And if you happen to get one that is not compatible with your vehicle, you will be left with a sealer that does can not properly seal the valves. For that reason, you should check the compatibility first.
- Build Quality
After considering the compatibility, you will have to factor in the build quality. In this case, you need to consider whether the parts that you are receiving in the package are of high-quality materials or not.
If they are not, you will not be able to get a reliable and long-lasting sealing performance out of them. For that reason, you should only get those that are of high-quality materials.
Most of the packages that you are going to stumble upon in the market will not include grommets. And if you get one that does not include them, you will either have to repurpose the old ones or have to purchase some separately.
Repurposing old ones are something that we would advise against. And purchasing them separately means you will have to spend extra money.
For that reason, we highly recommend getting the ones that come in a complete set and include all of the parts that are required for a fresh installation.
- Installation Procedure
One of the important factors that you would have to consider while buying these is the installation process.
Usually, the ones that meet the standards of OEM will be easier to install. You would not have to go through any hassles for those. And those are the ones that we would suggest you to opt for.
- Ability to Work Under Heavy load
Usually, when the engine is in a heavy load, it is going to produce a substantial amount of heat. And if the seals can not withstand those high temperatures, they will melt.
When they melt, the seal will be broken, which will result in fluid leakage. So you should only go for the ones that can withstand high temperatures without melting.
Another important thing that you need to consider while buying these is the seal. If you happen to get one that does not offer a strong seal, you might still have to face leakage problems.
Alongside that, those will be inefficient in the case of keeping the dust and debris away from the core components. Keeping those in mind, we highly suggest opting for the ones that can offer a strong seal.
How to Install Valve Cover Gasket?
Now that you have gone through the buying guide and the review, you would want to know about the procedures you would have to follow to install these, right? Well, these are the steps that you would need to follow for installing one of these:
Step 1: Let the Engine Cool Down and Remove the Core Components
The first step would be to let the engine cool down. It is advised to let it sit an entire night if possible.
After it cools down, you will have to remove the brackets of the spark plug, throttle cables, hoses, and other things that are on the way. Then you need to remove the cover bolts of the valve.
Step 2: Lift the Cover and Remove the Old Gasket
The next step would be to take off the cover of the valve. Then you should remove the old gasket. If you need to scrape it off, we recommend using thin plastic materials to avoid any leakage.
Step 3: Clean the Surface
Next, you should clean the surface properly. Remove all the oil and dirt that might be on it. If the instruction manual states that you need to use silicone, then you will have to apply it and wait for it to cure.
Step 4: Install the New Gasket
Once the surface is clean and the silicone is cured, you need to place the new gasket on the slot. Put the cover back on and tighten the bolts accordingly.
