Getting New Valve Springs: 5 Points to Consider

The performance of your engine can hinge on the quality of your valve springs. These small and often overlooked components are responsible for keeping your lifters in contact with your camshaft. Once your valve springs become worn out and brittle, they will need to be replaced right away if you want to keep your vehicle at peak performance. There are five things you need to bear in mind when shopping for new valve springs.

5 crucial valve spring specs

  1. Free length - This is the total length of your valve spring when it is neither installed nor under compression. It's measured by taking the total end-to-end length of the unloaded spring. This measurement directly affects the amount of pressure it exerts on the valve seat once it's installed.
  2. Installed height - This is the total length of the spring after it's been installed (with its retainer and all the necessary components attached). This is measured by taking the distance between the outer edge of your spring retainer and the bottom of the valve shims. The valve shims can be used to alter the installed height.
  3. Installed load - This is the amount of force exerted by the spring against the valve seat after it's been installed and with the valve completely closed. This is also known as seat pressure.
  4. Open load - This is the total amount of pressure applied by the valve spring when the valve is at its extreme open position. This value is directly affected by the overall design of the springs.
  5. Coil bind - This is the state wherein the valve spring is as fully compressed as possible and its coils are in contact. The amount of space between the coils before it's put in that state is equivalent to how far the spring will allow the valve to open.

Knowing these specifications will allow you to select the right springs for your vehicle.

Valve spring design

Other than the aforementioned specifications, it is also worth noting what kind of valve springs you should get depending on the kind of driving you will be doing. For example, titanium valve springs are designed for the short-term needs of high-performance drag racing competitions. Helical round wire springs, on the other hand, are far more common and are used for more casual driving.

How to Replace Your Valve Springs

The performance of your valve springs directly affect the performance of your vehicle as a whole because of the crucial role they play in letting your valves close and keeping your camshaft in contact with the lifter. Because of the high-temperature environment and normal wear and tear, your valve springs can weaken and become less effective with time. When you start experiencing valve float, getting new springs can restore your vehicle to its optimum performance. Replacing your valve springs is a garage project you can undertake yourself with the right tools.

Difficulty Level: Moderate

Here's what you'll need:

  • Ratchet and socket set
  • Valve spring compressor
  • Compression tester
  • Magnetic pick-up tool
  • New gaskets
  • New valve springs

NOTE: Make sure your engine has cooled over a few hours before you begin this procedure. These instructions were written with a Chevrolet small-block V8 engine in mind. Certain steps may be different for your particular vehicle.

Step 1: Open the hood of your vehicle and use your ratchet and socket to remove the valve covers.

Step 2: Use your ratchet and a 5/8-inch spark plug socket to remove all of the spark plugs. Take your compression tester and screw its spark plug adapter hose into the first plug hole.

Step 3: Attach the compressed air supply to the tester hose so the air pressure keeps the valves closed while you replace the springs.

Step 4: Use your valve spring compressor to compress the spring on the first valve. Use your magnetic pick-up tool to remove the keeper locks at the top center of the spring retainer so they don't fall into the engine. Extract the spring then remove it from your spring compressor.

Step 5: Place one of your new springs and the spring retainer into your spring compressor. Compress your new spring. Install it onto the valve stem along with the keeper locks. Remove your spring compressor. Repeat the process for the remaining valves. Take this opportunity to replace the valve gaskets as well.
