By this I think you mean the top of the engine.

You got me. It does'nt sound like the knock sensor boss.
There is no need for a screw in plug in the knock sensor boss.
What size is that set screw? Could be Mazda decided to put a plug
in there. You might have some post 1993 rotor housings with
the knock sensor bosses. When you bought a new one did you show
them the old one? Maybe all replacement rotor housings are
the late type.

I don't believe so, Paul.  My friend, the one who received the "Quality
Remanufactured Mazda Product" (ie rebuilt Manny Motors engine) had
brand-new rotor housings *yet* they were of the older pre-89 derivative.
