Review on PQYRACING Aluminum Valve Spring Compressor Tool - DOHC Compatible with Subaru WRX STi Forester Legacy Outback Baja - Black by Jeff Leu

Great tool for dohc subaru j325 engine. Replacing the valve guide seals initially took several hours. The guards went no further and are flying over the garage and they will never be found again! The second head with this tool only takes about an hour. I didn't really get it until the fourth. Install them first, then point them down until they are past the valve stems. Let go slowly. Did! Be sure to tap the valve stems with a soft mallet to ensure they are seated and not loosening. When I found this I did it and had to reinstall it.
