I was watching the video titled “How To Remove Valve Springs In The Car” (the one using compressed air to hold the valves in place), and had a few questions before I try to change the seals:
1. Rather than using a compression tester hose with the schrader valve removed, would a leak down tester also work? Is there any particular reason not to use that instead? Just curious – I do have both.
2. Should it be set to any particular PSI on the compressor?
3. Does it matter if the compressor isn’t that big? It’s 50L/3HP, and I wouldn’t want it to suddenly run out of air half-way through the procedure. I also have washing line as an alternative if that’s less risky.
4. I plan to join a narrow neodymium magnet to the end of a cord and have it ready in case things go wrong. Are there any better ways to pull the valve back up?
