Review on 🔧 Ruien Valve Spring Compressor Tool for LS1 LS2 LS3 LS6 LSX LQ4 LQ9 4.8 5.3 5.7 6.0 6.2 Engines: Compatibility and Efficiency by Michael Lara

This is a great tool for replacing valve seals. This came in handy for my 5.3 liter GM engine. As other reviewers have said, take your time, lube the bolt and I put a washer between the nut and the piece of metal. There were never any streaks or creases on the parts. Now compress the spring, remove the clips and remove the gasket is no problem. But I quickly realized that once you've installed the new gasket and are ready to put the spring back in, you should pay attention to how the spring compresses when you tighten it enough to put the brackets back in. Keep an eye on the valve stem and make sure it stays centered and right in the middle of the spring as you compress the spring. Due to the position of the tool and the angle at which the tool pushes the spring down, the stem may be off-center when you lower the spring enough to engage the detents. And then you can't insert both holders and have to pick the tool back up and try again. Usually after 3-4 turns of the nut you can pretty much see the angle the spring is moving and have a good idea of where it will be when it's time to insert the detents. And it has yet to be sufficiently weakened. This will allow you to position it correctly so that the stem is centered when you are low enough to insert the brackets. I used a 13mm ratchet wrench to compress the spring. Much luck
