What Is An Intake Manifold?
In order to better understand the function and form of the intake manifold gasket, let’s first examine the job of the intake manifold. Found on any vehicle with an internal combustion engine, the intake manifold sits on top of the engine and plays a key role in the combustion process.
Designed to run on three timed components, air mixed fuel, spark, and combustion; the internal combustion engine relies upon the intake manifold to help it breathe. Featuring a series of tubes, the intake manifold ensures that the air coming into the engine is evenly distributed to all the cylinders. This air is used during the first stroke of the combustion process.
The intake manifold also helps cool down the cylinders to prevent the engine from overheating. Coolant runs through the manifold to the cylinder heads where the coolant absorbs the heat and reduces engine temperature.
This brings us to the intake manifold gasket. Typically made from aluminized steel coated in a carbon-based rubber compound, the intake manifold gasket seals the intake manifold to the engine. High-quality intake manifold gaskets, such as Fel-Pro®, are constructed as one-piece with reinforced edges and linings around each port or runner opening. They must be resistant to decay caused by oils and coolants. The performance of your engine depends upon the quality of the intake manifold gasket.
If you notice any of the following symptoms, it could be a sign that your intake manifold gasket is wearing out. Consult your professional mechanic for a definitive diagnosis and repair.
Coolant leaking from vehicle
Green, red or yellow leaks under the car
Check engine light comes on
Engine starts to run rough

How To Care For Your Car: Intake And Exhaust Valves
Engine valves are small, but they play a huge role in keeping your car running smoothly. If there is an issue with the valves, such as bent or burnt valves, it must be addressed immediately to prevent engine damage.
What are the symptoms of a bad exhaust valve or bad intake valve? How much will it cost to repair bent or burnt valves? Keep reading to learn the answers to these questions and more.
What are intake and exhaust valves?
Intake and exhaust valves are the final component in the valve train system. They are made of hardened metal that must withstand the extreme conditions of the combustion chamber.
Intake and exhaust valves are responsible for controlling the flow of gases through the combustion chamber. Intake valves let air in, whereas exhaust valves let air out.
They are shaped to have a slim stem leading to a flatter face, with the intake valves often being larger than the exhaust. Each valve is designed to only move up and down, not side to side.
When a valve is closed, it sits tightly on the valve seat to stop the flow of air. But when it is open, it separates from the valve seat to allow air to flow through.
In many modern engines, each cylinder has two intake and two exhaust valves per cylinder.
How to Tell Your Car Has a Bad Intake Manifold Gasket
The intake manifold gasket in your car’s engine keeps the various fluids from mixing and leaking. Learn here how to tell if your car has a bad gasket.
A car's engine creates power through the combustion of air and fuel. In most modern, fuel-injected systems, the air and fuel mix together inside of the component known as the intake manifold. One end of the manifold consists of a single tube through which fresh air flows. The other end consists of multiple smaller tubes, each of which connect to one of your engine's cylinders.
Between the intake manifold and the engine block sits the intake manifold gasket. The intake manifold gasket seals off the small gap between the manifold and the engine, preventing air, coolant, and oil from leaking. Over time, the intake manifold gasket endures a lot of wear and tear. Eventually it may crack or warp in ways that allow leaks to occur.
