Mysterious oil leak

Ok, This has been an issue I've been avoiding for awhile, but today I was under the car and was reminded the very persistant oil leak that my car has had recently.

The source of it has been hard to pin down. I originally thought it was the oil pan gasket, but that has been replaced and the leak didn't go way. I also tried some magic high mileage leak prevention oil out of desperation but that didn't help either. The leak seems to be coming off of the driver's side somewhere, but despite that, oil gets all over the bottom of the engine, k-brace, and sway bar. My last educated guess is the sensors, but before I go drain all the oil out of the car AGAIN, I would like to ask: is there any other possible place My RX-7 could be leaking oil?

you can always try spraying your engine down with some degreaser around that area, and i that would make it easier to pinpoint the location of the leak.

I've had leaks from the oil cooler and the omp to block o-ring, degreased, hosed, and it was easy to pinpoint after a drive.
