Review on 🔧 Optimized Digital Diesel Compression Test Kit - Mityvac MV5535 by James Nielsen

Bought for a compression test on a 6.7 liter Cummins with 124,000 miles, replacing all 6 injectors. The engine ran well, the injector did not smoke. I was expecting less than ideal compression, but not what this digital sensor showed me. Cylinder 1 showed 16psi. 350+ with such a spread and low numbers, my engine almost wouldn't start, smoked like a freight train and had no power. The 60 second cylinder was leaking at 120psi and had 0 strokes on all cylinders on a 2 day cold engine. THIS IS A SENSOR! The truck caught fire immediately after filling and ran smoother than new. Don't buy this unless you plan to use the analog gauge kit and ditch the digital
