The oil pump comprises an open ended conduit extending from a connecting rod journal to below the surface of oil in a crankcase. The glass core substrate includes a glass core and build-up structures on opposing sides of the glass core. A single crystal semiconductor plug is formed to penetrate the interlayer insulating layer. When the detection value of the viscosity of the lubricant output by the cam chamber sensor has become the predetermined allowable value or below, the three-way electromagnetic valve is controlled to turn OFF so that the output side of the oil separator communicates with the check valve and the bypass route is cut off. The systems further insert at least a portion of the check data into an ACH transaction entry for ACH transaction processing.
