How to Install a Valve Spring

A valve spring is a widely used device that keeps a valve locked in the head of a cylinder within a combustion engine. Checking valve springs in your car is necessary to ensure that the valve stems and guides of your vehicle don’t wear off prematurely. Improperly installed or damaged valve springs may cause clattering in the valves, adversely affect your engine’s rpm, and lead to the damage of the valve train.

Installing valve springs is a moderately simple project. Using the following tools and equipment, as per the steps mentioned below, you can go about it with little difficulty.

Tools and Equipment Needed:

  • Safety Hood
  • Hand Gloves
  • 10 mm Socket
  • Ratchet
  • Breaker Bar
  • 14 mm Socket
  • Paper Towels
  • 12 mm Socket
  • Pliers
  • Oil Lube

Step 1: Remove the Equipment

Wearing your safety hood and hand gloves, remove the cover of your car’s spark plug, plug wires and the valve cover using a 10 mm socket on a ratchet. Remove the fuse box found under the hood and loosen both the gear bolts and the tensioner bolt using your breaker bar and a 14 mm socket. See to it that you do not apply too much pressure on the bolts. Loosen them patiently to avoid any possible damage to them. Moreover, remove the cam holder plates too by loosening the 10 mm bolts outside and the 12 mm bolts found inside. Place all these removed devices safely on a clean cloth.

Step 2: Remove Valve Springs and Retainers

Locate the oil passages in your car and plug them up with paper towels. Once the placement is done, put your 12 mm socket over the retainer in to loosen the valve keepers surrounding the retainer. Once done, remove the retainer and the valve springs to expose the covered valve seat and valve stem seal. Then, using your pliers, remove the valve stem seal and install the valve seat by placing it over the valve guide.

Step 3: Install the Valve Stem

Once the valve stem has been installed, lubricate the rubber part with oil lube and place it over your valve stem. See to it that it is situated straight and is not slanted or crooked. Proceed forward by taking the 12 mm socket from the handle and placing it over the steam seal. Moreover, assure that the valve stem seal fits in perfectly without causing any damage to the rubber or spring.

Step 4: Install the Valve Spring

Lastly, position your valve spring back into the top of the valve seat and place the retainer back on the valve spring. Lube the valve keeper and place it in the retainer. Put the valve springs over the retainer and the valve keeper combo. Try to keep the installed valve spring as straight and accurate as possible.
