Yeah, I might owe you a cold beer, or a hot toddy, or whatever is appropriate for the season. I was looking for an easy but obscure answer for you. I've had them leak through the weep hole, and I'd swear the pump was fine 'til I stuck my finger under there and felt the drip.

Years ago I solved a weird oil leak in a weird way. I washed down the engine to remove crud, and then sprayed underarm antiperspirant all around the suspect area. This (female) antiperspirant was the type with talcum powder—so it made a white powder coating stuck to the entire surface.

The oil leak left a tiny black trail in the white powder.

I don't know if you can still buy that type of underarm spray—they've probably discovered it glows in the dark, eats the ozone layer, and is the prime reason for global warming. And besides that, it gives users a itchy pits and makes 'em mean.
