Its a drain hole for the area the spark plug is in. Also to blow compressed air into to clear that area of debris before removing the spark plug.

Ditto!

One time I was at a local electrical supply house and I came across some cool looking wire. It was 3 braided 24 ga wires and was pink,lightblue, and a dark purple color. I bought a few feet and epoxied one end in this hole and the other end to a My-chron data aquisition equipment.

Drove some peole mad till our mechanic walked over one day and just yanked it out.
