PressCheck | 18-Piece Diesel Compression Tester Kit | Cylinder & Injector Testing
Description
Find Out Whether the Engine Is Worth the Repair
Before you spend two thousand dollars on a diesel that smokes, you want one number per cylinder. A compression test tells you whether the bottom end is healthy or whether you are about to rebuild an engine that is already finished. 18 pieces covers the common glow plug and injector port adapters.
Why You'll Love It
- 18-piece adapter set – fits the common glow plug and injector ports across diesel engines
- High-range gauge – calibrated for diesel pressures, not a petrol gauge pressed into service
- Quick-release fitting – test one cylinder, dump the pressure, move to the next
- Reads dry and wet – a wet test tells you rings from valves, which changes the whole repair decision
- Molded case – adapters stay identified instead of loose in a drawer
