Review on πŸ› οΈ Enhanced OTC 4573 Universal Overhead Valve Spring Compressor for Improved SEO by Rudy Santos

Revainrating 4 out of 5

Well made, seal replacement is a breeze, no strain on your hands

Worked very well for replacing valve seals, brackets and brackets on my head mounted BMW. I had to trim some of the silver interior to fit my specific application but it's no big deal Can't expect it to fit perfectly on every head. Once I figured that out everything was a breeze. After fitting 24 M3 valves it wasn't too hard on the hands. Can be more painful if you have extreme valve springs I recommend it for replacing parts of the valve mechanism with the head in place.I used a leak tester to pressurize the combustion chamber to keep the valves closed.

Pros
  • Includes two spring adapters; Fits valve spring retainers up to 1-13/16" in diameter; jaw opening 1-3/8 to 5-5/8 inches; Neck clearance 5-7/8"
Cons
  • Compatibility
