I found it easy to use and very effective. You will need a small wrench to tighten the tool into the spark plug opening. I ran about 40 PSI on the unit and left my air compressor running as needed. **Q: Will this work on a small block Chevy 350 ?** A: YES! It will work on Chevy 350, 305, any small block. The two thread sizes it comes with fits most cars. **Q: I used it, the high pressure tube blew out at 60psi on the very first use, the return window is closed, will you take it back?** A: If you're changing valve seals you only need 35 to 40 PSI. **Q: Do you make a solid tube for when the spark plug is recessed several inches? Where a flexible valve holder cannot be tightened.** A: My spark plug is recessed about an inch if that and I used an old 3/8 wrench and bent the end so that I could get in to the recessed area and tighten the fitting. You do not have to make it very tight to get a seal. If your plug is recessed several inches, then I think the only option you would have would to be make up a tube that would slide over the air hose on the kweiny and use that to tighten the fitting.
