I have a question for you too Paul. After initial break-in and loss of pressure, is it assumed that valve springs are stable and will last forever? Or will they wear based on cycles that decline over time with use? My thinking here is the decline after breakin might be slow but still there and wanted to get your thoghts.
After the initial break-in the pressures stabilize and stay like that for a long time. Sometimes we'll shim up expensive roller springs depending on the application. But for the most part once the springs start to loose pressure after the initial break-in they're replaced.
