Condenser fan motor-
the plastic oil plug is broken off – the one you take out to oil the motor bearings
any way to get it out?
drill? or does that put chips into the bearing
ignore it ? 15 yrs old motor never oiled
if they do come out how replug the holes?

Use an undersized drill bit in a hand vice. Work the drill bit in a ways and then pull. Or if you have an appropriately sized tap, that will work even better.
You can probably buy replacement caps at a motor shop, though there's little harm in leaving the cap off.
Are you sure that they plug is actually an oil point? Most motors in these devices have sealed bearings and plastic condensate drain plugs. Idea being that you remove the one on the low end, most of these motors are universal and can be used shaft up or down depending on the condenser it is mounted in, so that any condensation that forms in the motor housing has a way out.
I have replaced a few condenser motors where the bearings failed in short order after the motor was mounted and the plug not removed or the wrong one removed. Usually I find standing water in the motor and the sealed, such a relative term, bearing seized up.
If the plug is the one lowest most opening a passage for moisture would be a good idea. Getting the plug out ideal. Perhaps drilling a tiny hole in the plug and teasing the plug out with a hooked piece of fine steel wire would be good. Worse case I would split the housing, after marking the alignment, and use a bit of wire to push the plug out from the inside.
If the plug is one on top or uppermost I wouldn't worry about it. I would seal the hole with a small square of good quality of foil tape firmly burnished into place.
thanks
plug is the lower one
but its a shaft down motor and the upper plug and motor "top' is well shielded from the weather by the assembly that holds the motor.
