Default Help! Oil Leak maybe rear main?

I have a 12' WRX Hatch, my front crossmember is soaked in oil and small puddle on floor. Oil on the rear of engine oil pan, ps rack covered, and bottom of transmission front to a little past the drain plug. Transmission level is good and engine oil level is good as well. Power steering is a little above cold min. The oil leaking is amber/brownish looks like either engine or gear oil. Any thoughts or suggestions?

Jack the car up and Clean up the areas with brake cleaner or equivalent. Start the car up and make sure you have a flash light and start looking. If there is that much fluid then it should be noticeable right away where itís coming from. Hopefully an easy fix and good luck!

If you've just noticed this, then keep a vigilant eye on engine and trans level, just in case, and also do as boone91 says.

That said, the "GR" era WRX and STi have a common failure point in the power steering pinion housing. They leak power steering fluid. It's possible to replace the seals to remedy this leak. If you're interested at all in upgrading your steering ratio, the 15+ STi has a quicker ratio. It's a direct swap and since your rack has to come out anyways, this would be the prime opportunity to upgrade. That way you fix the leak and upgrade at the same time.
