Review on OTC 5021 Universal Diesel Compression by Pete Deutsch

Revainrating 5 out of 5

excellent cal.: spare parts

is a good compression sensor. It's not easy to find 1/8" quick connect adapters, but this gauge comes with a 45 degree quick connect adapter with a built-in one-way valve. Some brands of head adapters have a valve core, but OTC does not, and you need this valve to properly measure compression.

Pros
  • absolute legend
Cons
  • not the best
