Valve springs are used to keep the valves closed when the engine is not running. When the engine is running, the camshaft pushes on the valves, opening them. The valve springs then close the valves when the camshaft moves away.
Valve springs can become weak over time, which can cause the valves to not close properly. This can lead to engine problems, such as loss of power and decreased fuel efficiency. Replacing valve springs is a relatively simple task, but it requires the use of a valve spring compressor.
There are two types of valve spring compressors: manual and hydraulic. Manual valve spring compressors are operated by hand, while hydraulic valve spring compressors use hydraulic pressure to compress the valve springs. Hydraulic valve spring compressors are typically more expensive than manual valve spring compressors, but they are also more powerful and easier to use.
To use a valve spring compressor, first remove the valve cover. Then, position the valve spring compressor over the valve spring. Compress the valve spring until the valve keepers can be removed. Once the valve keepers are removed, the valve spring can be replaced.
When reinstalling the valve springs, be sure to install them in the correct order and orientation. The valve springs are typically color-coded to make this task easier. Also, be sure to apply a small amount of oil to the valve springs before installing them. This will help to prevent them from squeaking or binding.
