Where are the intake and exhaust valves located?
Engine Intake and Exhaust Valve Basics. Engine valves are located in the cylinder head. The main function of the engine valves is to let air in and out of the cylinders. That air is used to help ignite the fuel which will drive the pistons up and down. There are two types of engine valves; intake and exhaust valves.
How does the exhaust valve open and close?
Once the piston goes through the compression and firing stroke, the exhaust valve will open and let the exhaust out. It then closes immediately after. But you may ask how do the valves open and close? There is a shaft that pushes on the all the valves called a cam shaft. Be sure to check out the cam shaftlink for more information on the camshaft.

What causes a valve to stay open in an engine?
This causes several different problems within the engine: A valve can get into non-sealing state for several reasons. These might include, but aren’t limited to: Any one of these can cause a valve to stay open during the combustion event, which allows very hot gases to escape past the valve.
What kind of intake and exhaust valves do you use?
Our selection includes stainless steel intake and exhaust valves from companies like Manley, AFR, Chevrolet Performance, Ford Racing, Dart, Edelbrock, and more. Many of these valves are machined, swirl polished, and have hardened tips for dependable, long-lasting performance. Choose from a variety of diameters—from . Read More
Why do I have carbon deposits on my intake valve?
Sticking valves, can also be a sign that there are, carbon deposits on the valves. Often, carbon deposits are, the result of a rich fuel mixture. It can also be, the result of, oil passing through a worn valve guide. So, oil is pulled through the intake valve guide and into the combustion chamber, where it’s burned.
What causes a cylinder head valve to stick?
Irregular valve sealing with cylinder head valve seat. Carbon residues generated by irregular combustion; will jeopardize the sealing between the valve and its seat. Incorrect valve clearance, can jeopardize the valve sealing, causing this type of failure. Running a dry fuel, such as L.P.G resulting in inadequate lubrication.
What to do about carbon build up in valves?
Use good quality fuels, to help prevent carbon build up on the valves. And, regularly check the valve clearances. Irregular valve sealing with cylinder head valve seat. Carbon residues generated by irregular combustion; will jeopardize the sealing between the valve and its seat.
