Valve springs in a cylinder head serve to control the opening and closing of the engine's intake and exhaust valves. They ensure that the valves return to their closed position after being opened by the camshaft, maintaining proper timing and preventing valve float at high RPMs. Additionally, they help maintain the necessary pressure on the valves to create a tight seal against the combustion chamber, optimizing engine performance and efficiency.
What else can I help you with?
Where are the cylinder head casting numbers located for Chevy small block?
Under the valve cover where the valve springs are.
Do you take off the valve springs to get the head off?
No. The valve springs can remain on the head when removing the head.
What is meant by a valve spring compressor?
A valve spring compressor is used to remove collets in a car. The tool compresses the valve springs in the cylinder head of the car allowing the collets to be removed.
Is the intake or exhaust valve located in the cylinder head on a overhead valve engine?
Type your answer here... They are in the cylinder head.
What is the function of valve stem seals?
Valve stem seals help prevent oil from leaking into the combustion chamber through the valve guides. They also help control the lubrication of the valve stems and guide them properly within the cylinder head.

How to compress valve springs?
If the head is still on the engine, you can purchase a kit at most auto parts stores that includes: an air fitting to keep the cylinder filled with compressed air to prevent the valve from dropping into the cylinder, and a special wrench to attach to the rocker stud and press down on the spring retainer while you remove the locks. If the head is off the engine, you will need a valve spring compressor, which is a large c-shaped tool that pushes on the valve's head on one end and the valve spring retainer on the other end. Also you can buy/rent a valve spring compressor that you can use while the head is still on the engine but you will still need to blow air into the cylinder through the spark plug hole to keep the valve up.
What is the engine upper end?
The cylinder head and valve gear.
How do you replace valve seals on v8- 89 Chevy truck Ive heard stories of using air pressure to lift pistons and What is the difficulty?
First of all the air is for holding the VALVES up in the head so they don't fall down into the cylinders when you take the valve springs off of the valves. You should have a trained mechanic do that job for you. If the valve falls out of the head then you will have to remove the cylinder head to get it out.
What is sub assembly of cylinder head?
The sub-assembly of a cylinder head refers to the collection of components that make up the cylinder head before it is fully integrated into an engine. This typically includes parts like the valves, valve springs, camshafts, and rocker arms, which are assembled together to facilitate the intake and exhaust functions of the engine. The sub-assembly is crucial for ensuring that the cylinder head operates efficiently, contributing to the overall performance and functionality of the engine. Once fully assembled, the cylinder head is then mounted onto the engine block.
Is a valve gasket and a head gasket the same thing?
Valve cover gasket holds oil from the valves from leaking off the top of the head . Head gasket is lower and holds cylinder pressure between the cylinder head and the engine block.
Where is the intake valve on a 2000 Olsmobile Alero?
There is one intake valve for each cylinder. It is located in the top of the head. If you remove the valve cover, you can see the stem of the valves by peeking through the caps in the valve spring. If you want to replace a valve, it will be necessary to first remove the cylinder head.
