Using the listed DIY project instructions found here, I have some questions.

1. Where can I find the tool with the whistle on the end and a fitting that I can attach to a compressor for pressurizing the cylinder to keep the valves from falling into the cylinder?

2. Would a valve stem seal kit (comes with the pliers) found on eBay be useful or should I just get the pliers itself.

3. There a protective cap advertised here that goes over a spring compressor tool to protect the surface of the head from damage. Should spent the $40?

4. In addition of a new valve cover gasket, I though I would also buy a can of the CRC Intake Valve Cleaner. Is it worth it?

5. Will renting a spring compressor kit from my local Autozone be suitable for this project?

6. Any other tips or suggested parts to purchase for this project?

Thanks,
AL
