This is mainly a PSA and "lookie what I found" for posterity, in case somebody someday searches. My new iS has terrible oil leaks while running. I tracked down the 3 major leaks on the right side.
1. oil pressure sensor.
2. Somewhere above the AC compressor.
3. The wire that goes to the windshield washer pump, about 2 inches from the pump, where the black sleeve ends
So here's how it is as I see it:
Crappy oil sensor leaks oil thru the sensor into the connector, which is covered by a beautiful, supple yet firm nipple. The nipple, being in perfect shape, directs the hot, pressurized oil into the black sleeve that covers and protects the wire.
The wire then snakes along the block up above the compressor, where it joins with another sleeved wire into a larger black sleeve and travels above the fan clutch area.
That "other wire" happens to be the wire that goes to the windshield pump.
Pressurized oil is being pumped into my engine's wiring harness. Some is exiting immediately at the sensor. Some is making it above the compressor where the wires join and leaking down, and some is making it all the way back up to the windshield washer pump. I'm assuming some is making it to the left side of the engine and causing my leak on that side, but since I haven't traced the wires that far yet I can't conclude that for sure.
I might take some photos tomorrow if there is interest.
My new sensor gets here on Thursday along with my timing belt, so I should have a pretty good view of what's going where when I do that job.
