Although valve cover gaskets don't necessarily need sealers or cements, it's a common practice to glue the gasket to the valve cover. There are a number of sealant choices, too. For this application, Permatex No. 1, RTVs or Permatex High Tack gasket sealant work well.
How often should valve cover gaskets be replaced?
Most modern engines have much better gasket materials, and then should only be replaced when they leak, or in some cases when a valve clearance adjustment is specified as regular maintenance. The interval on a lot of newer cars requiring clearance adjustments typically goes into the tens of thousands of miles.

What happens if you drive with a valve cover gasket leak? Your engine will just lose oil. If this goes on very long the oil level will drop too low and the engine will be damaged.
Is it safe to drive with a valve cover gasket?
Not really, unless you let it leak enough to be below minimum oil capacity to properly clean and lubricate the engine internals. If it's bad enough, it could burn, but highly unlikely. A leaking valve cover gasket could also cause a vacuum leak, which will cause the car to operate inproperly.

2 days would be a good safe bet. But at least overnight. If you drive it within an hour it's guaranteed to start leaking sooner than later. What are the symptoms of a bad or failing valve cover gasket?
Is it okay to reuse valve cover gasket?
There should be no issue in reusing new rubber valve cover gaskets. I don't have experience with cork gaskets, but assuming they don't permanently deform under load then even these should be reusable. Since there are only a few weeks old and you didn't use sealant, you should be able to reuse them.
How bad is a valve cover gasket?
A worn or leaking valve cover gasket can cause oil to escape and allow debris and small particles to enter the space between the pistons and cylinder, resulting in friction and increased wear and tear.
Should you put silicone on valve cover gasket?
Most engines built in the last 25 years use molded rubber gaskets to seal valve covers and oil pans. With these types of advanced gaskets, the overuse of RTV and other types of silicone sealers or other additives will prevent the gasket's ability to form a reliable seal, causing leaks.
Do you need silicone when replacing valve cover gasket?

Can I reuse a new gasket?
Once a gasket has taken a set (due to temperature and fluids), it should not be disturbed or reused. It would not have the same properties available to go through the initial compression provided by the joint and achieve the initial seal.
Is it OK to reuse gaskets?
Generally no, it's not a good idea unless you like doing repairs twice. The choice is pretty much up to you. I reused cork rocker cover gaskets many more than ten times with no problem. I used sealant to glue them to the covers so they came off with the covers and were not damaged.
Do rubber valve cover gaskets need sealant?
Another indicator of valve cover gasket failure is an increase in engine noise. If the gasket is not sealing properly, it can allow air to enter the engine, leading to an increase in engine noise. This can manifest as a knocking or tapping noise that may be more noticeable at certain RPMs.

Silicone sealant should almost never be used where a paper, cork, metallic, or rubber gasket is intended. For instance, it shouldn't replace a cylinder head gasket or a rubber oil pan gasket that the manufacturer requires.
Can I use normal silicone as a gasket?
A valve cover gasket is usually fiber or rubber and all it does is deal against oil leaking out. A head gasket seals between the head and the block, is made of metal, and is subjected to high heat and pressure. A blown head gasket and your car doesn't run correctly, if at all.
How do you seal a valve cover gasket?
You will lose oil but not power. If part of the 'bad' gasket has lodged in the valve spring area or entered the oil pump then that debris will cause a power loss. As long as your valve cover gasket stays leaking you will continue to loose oil. And you only have 4 or 5 quarts to loose before your engine DIES.
What is the difference between a valve cover and a gasket?
Unbolt the bolts that hold the valve cover down with a 1⁄4 inch (0.6 cm) drive ratchet. Lift the valve cover carefully to contain debris from falling into valves and springs. Pull off old gasket and clean the valve cover in degreaser or hot soapy water. You could use a wire brush and a 5 gallon (18.9 L) bucket.
How much oil can you lose with a bad valve cover gasket?
In general NO, not directly, because the valve cover and gasket is not part of the pressurized oil system design of most engines. Low enough oil level will cause low Oil pressure and a bad valve cover gasket can leak enough oil to cause low levels.
Can I replace a valve cover gasket myself?
A bad valve cover gasket can prevent a car from starting by causing a loss of oil pressure. This can happen if the gasket is damaged or if it is not properly sealed. If there is a loss of oil pressure, the engine will not be able to start.
Can a bad valve cover gasket cause engine failure?
If the gasket is worn out, it will leak engine oil and the top of the engine will be likely be covered in oil. It can also expose your engine to dirt, debris and other pollutants with the ability to cause permanent damage. You'll need to get an immediate replacement to prevent serious damage to your engine.

Do valve cover gaskets leak oil?
The valve cover gasket seals the connection between the cylinder head and valve cover. With a small leak there are minimal consequences as long as oil is regularly checked and added as needed. With a more severe leak you have more oil loss with results in a greater opportunity of starving the engine of oil.
