1. A timing light adapter for reflecting light energy off a timing mark of an internal combustion motor, said timing light adapter comprising:

  • a first light transmissive body having a proximal end and a distal end, said light transmissive body defining a first light transmissive channel carrying light energy between said proximal and distal ends thereof; and

    a second light transmissive body having a proximal end and a distal end, said second light transmissive body defining a second light transmissive channel carrying light energy between said proximal and distal ends thereof, said first and second light transmissive bodies being coupled together while maintaining said first and second light transmissive channels substantially independent of light energy interference therebetween whereby, upon positioning said proximal end of said first light transmissive body adjacent said timing mark and upon positioning said proximal end of said second light transmissive body adjacent said timing mark, light energy injected into said distal end of one of said first and second light transmissive channels travels therealong, emerges at said proximal end of said one of said first and second light transmissive channels, strikes said timing mark, reflects off said timing mark, enters said proximal end of the other one of said first and second light transmissive channels and travels therealong, and emerges from said distal end of said other one of said first and second light transmissive channels, said first and second light transmissive bodies as coupled together providing a plug for insertion into an engine case of said motor to seal said case against escape of oil within said case while said motor operates.
