🔧 Lisle 16560 Valve Spring Compressor: Ideal Tool for GM LS Engines Review

Works fine. Get an extra hairpin, though! Local hardware stores don't have full-thread metric screws. So find it here. At the same time, I changed all 16 springs with no problems, but the threads are basically gone. If you can afford a tool that compresses two springs at once, get one. If you are on the same limited budget as me then this job will get done.

Most LS heads have a flat spot on the rocker arms but not LS7. It has a round swing seat with raised edges. These edges interfere with the tool. Also, the heads were machined before I received the car and I'm not sure if the springs are stock or not. At the same time, this tool hardly compresses the springs. I pulled two out before bending the tool unusable.

Reading other people's reviews about the threaded shaft breaking on the second pair of springs they were compressing made me willing to buy other hardware to fix the work to do. But I have disassembled and assembled 3 pairs of heads so far and the tool is absolutely worth the money. I simply lubricate the threaded shaft with oil throughout the spring removal/installation process and use the brass nut that comes with the kit. with him as head.

I only replaced one set of springs and the threads are already worn out. The stock LQ9 springs have been replaced with LS6 springs, eliminating the need for monster springs to weigh down the tool. Both sets have very soft seat springs. Properly lubricate whatever is used to reduce friction and wear. I would only recommend it if you plan to use it multiple times or even just once. Lisle is guaranteed, but consider the time, hassle, and shipping cost of a replacement.
