What‘s your experience with valve spring testers? I see there’s a wide range from leaky $60. Amazon ones to $800.- pro bench models. I’m thinking about getting something useful, where I could note pressures at installed height and max lift. Any recommendations?
Find a used Rimac tester they come up on eBay and other places. Figure what your highest open pressure will be and get one in that range. You can always ask to use one at a machine shop, my shop let me use theirs till I found a good used one.
