All the essential mechanisms in the car will have gaskets and cover for better efficiency. It plays a vital role in the engine because it includes many components. It is necessary to hold them tightly without gaps for proper functioning. Like other parts, the gaskets will also wear out over time and produce cracks and holes. Any leakage in the system will affect the function, and the engine starts to exhibit some unusual behaviors.
One of the essential components is the valve cover gasket, and it plays a vital role in the engine. The engine will expose some symptoms if the gasket fails. Please read this article to learn about the bad valve cover gasket symptoms and fix them quickly.
What Is Valve Cover Gasket?
A valve cover gasket is an essential part of an engine. Usually, there are two types, such as liquid gaskets and rubber gaskets. It varies based on the type and make of the car.
The valve cover gasket seals the valve cover and the engine cylinder head. The oil is the lubricant that flows throughout the engine and gets in contact with the camshafts, valves, and others.
It is the valve cover gasket that arrests the leak and allows the engine t operate effectively. A bad gasket will affect the engine performance, which over time, gets worse and ends badly.
The Lifespan Of The Gasket
The valve cover gasket has to arrest the leak, which makes it to contact the oil every time. Since it is made up of rubber, it degrades over time and cracks. The oil starts to leak through the cracks and affects the function. Generally, the gasket is effective for 35000 to 50000 miles, and the bad handling of the engine will reduce its lifespan. The engine starts to exhibit specific symptoms if the gasket is damaged. It is necessary to replace the gasket to resolve the issues.
Symptoms Of Bad Valve Cover Gasket
If the person notices the following symptoms in the car, then it might probably be a bad or damaged valve cover gasket. The problem should be resolved before it gets worse.
1. Oil Burning Smell
The oil travels to all the places in the engine to reduce friction so that the parts won’t wear out soon. The excess oil overflows through the cylinder head and other parts. The heat generated during the contact burns the oil, and also the hot oil touches the gasket. It might degrade the gasket over time. If the valve cover gasket is damaged, then the person can notice the oil burning smell. The person should check the gasket and replace it to resolve the problem.
2. Valve Cover Leak
The engine oil has to be replaced over time, and the mechanic will check the gaskets for the leak. The person can notice the oil around the engine if the valve cover gasket leaks. The leak not only outflows the oil, but it also takes in the dust and dirt particles.
The dust in the oil gets collected in the cylinder head and pushed out to the valve cover. If the person finds any cluster of solid oil, it is actually the dust that entered the leak. The waste oil has to be removed, and the gasket has to be replaced before refilling the new engine oil. It would stop the leakage.
3. Low Engine Oil
It is better to change the engine oil every six to twelve months for better functioning. If you notice your engine oil level dropping soon, there is a leak in the system. A bad valve cover gasket is not the only cause, but it could also be one of the reasons for leakage. It is better to inspect the gasket before refilling so that the leakage can be avoided. An engine running with low engine oil will increase the chances of the wear out and damages the components. So, Inspect and find the cause of leakage and solve it quickly.
4. Engine Misfire
An engine misfire could cause various problems and symptoms that affect the engine. Check out our article on engine misfire symptoms so that you can get a clear idea. Also, a bad valve cover gasket could cause the misfire in an engine. It could cause the engine to vibrate more than usual, and sometimes the engine might even shudder with more noise. The mechanic who repairs the engine misfire will also check the gasket and will replace it if necessary.
These are some general bad valve cover gasket symptoms that the person can notice in the car. A bad part of the vehicle will affect its performance and function, so it should be replaced soon. You cannot replace it on your own because the tasks are complicated, and it requires specific tools and skills.
Cost Of Replacement
There is no chance of repairing a bad gasket; the only solution is to replace it. A valve cover gasket costs around $30 to $50, but then comes the labor charge. Any general mechanic might charge an average of $300, and it increases to other popular auto services. If the issue is worse, then the cost of repair increases.
How To Increase The Life Of The Gasket?
The person should know how to handle the engine based on the exterior conditions. Mishandling of the engine increases the risk of damaging the gasket soon. Also, change the engine oil over some time as recommended. These steps will eventually allow the gasket to work to its extent and sometimes increases the lifespan.
It may be one of the smallest components in the engine, but it plays a vital role in its function. So make sure it is working correctly to maintain the performance of the vehicle. If you notice any symptoms of if your mechanic suggests replacing the gasket, then better do it. Ignoring such issues will end up worse and sometimes even worse.
