Properly working intake valves will give your engine more power and better combustion. To ensure precise air and fuel mixture, these valves need to open and close at the right time. Intake valve failure will result in poor combustion operation and reduced engine power. Replace damaged intake valves right away to prevent engine breakdown and to save yourself from high repair bills in the future.
Here are the tools you need and the steps to follow in replacing damaged intake valves:
Difficulty level: Moderate
Tools that you'll need:
- Valve spring remover tool
- Valve spring compressor tool
- Small magnet
Step 1: Compress down the valve spring using a compressor tool until the retainer is almost at the same level as the top of your car's valve stem.
Step 2: Using a small magnet, remove the two retainer clips holding the valve stem in place. Next, decrease the pressure on the valve spring. Remove both the spring and the retainer.
Step 3: Reach underneath the head and pull the valve out. Be careful not to deal any damage on the valve guide or valve seal while doing this process.
Step 4: Slide the new valve through the valve guide and seal. Make sure it is thoroughly cleaned of all carbon before installation.
Step 5: Put the valve spring on the valve guide. Position and secure the retainer on the spring. Using your compressor tool, compress the spring until the valve stem tip is visible.
Step 6: Place both retaining clips back around the valve stem. Make sure the tapered end is facing down.
Step 7: Release the spring slowly. While doing this, check if the retaining clips are seated correctly around the valve stem. Make sure the clips are also secured tightly against the retainer.
Installation time depends on your DIY skill level. The process can be time-consuming, but make sure each step is carried out carefully to prevent valve looseness.
