This is the Valve Spring Tool for the Subaru Imprezza RS, Forrester, Legacy with a EJ25 DOHC engine.
The Valve Spring Compressor is CNC machined, anodized purple, Laser engraved and made in USA.
This tool makes it easy to replace valve seals, valves, springs, and retainers. The tool is attached to the head with 2 cam tower bolts. Once the tool is attached to the head you put a retainer cap (comes with kit) on the retainer/spring(s) you want change next you tighten a bolt that will push down on the retainer allowing you to easily remove the keepers. Next simply UN-tighten the bolt and remove the retainer cap to remove the spring(s).
You can use this tool with the head on the block.
The tool is made so you can use your factory cam tower bolts that you removed when removing the cam tower.
