1. A compression gauge assembly for diagnosing pressure variances of an engine cylinder(s), the assembly comprising:

  • a) a gauge sensor in communication with the engine cylinder(s), the gauge sensor being operative to detect compression stroke pressures within the cylinder(s);

    b) a gauge controller in communication with the gauge sensor, the gauge controller including a comparator circuit operative to compare detected compression stroke pressures within the cylinder(s) and to derive the pressure variances therebetween;

    c) a gauge display in communication with the gauge controller for displaying the derived pressure variances; and

    d) a cylinder connector for communicating the compression stroke pressures from cylinders recessed in the engine, the cylinder connector having a first connector end in communication with the gauge assembly and a second connector end extendable to engage the recessed cylinders.
