I thought I would do a compression test on the motor while there were no injectors in. Was just curious on the health of my engine. After 6 or 7 compression strokes every cylinder had a peak pressure of 480 to 490 psi and then the pressure stopped climbing. Each cylinder jumped to 300 psi after just one compression stroke.
Some are Schrader, depends. So LMJD, in your 30+ years as a diesel mechanic, what was the max pressure you saw during any diesel compression test? Would a 0 - 500 PSI transducer be enough or do I need to go to 1000? There are a couple of 600 PSI transducers, but they aren't configured to match my project and aren't common, for whatever reason.1000 Psi Diesel Engine Compression Pressure Tester for Ford Cummins NAVISTAR Detroit. 4.0 out of 5 stars. 34. .99 $ 59. 99.
