Default Is this a leak, or just water from the hood scoop?

2011 WRX here.

I know that the iron section between the turbine and compressor sections on our turbos will develop surface rust pretty much immediately, but the other day I noticed a discolored section. Not sure if it's just from water dripping in through the scoop (it's rained on and off over the past few weeks) or if it could be a leak (is that an oil or coolant line?)

There's no oily residue or anything -- when I touch it it just feels like rust. It's not wet now AFAICT.

Any thoughts?

If it isn't wet but looks wet which it does it's probably oil, potentially from the feed line. Easy enough to get some new copper crush washers and re-bolt it down.

Quit putting the lotion in the basket about one tiny, tiny, tiny mark. Hell if you stuck your head under my hood, you'd throw up blood within 9 seconds. It could oil, water, or Cherry Coke....regardless, it is super tiny and the size says don't worry.

LOL! Didn't realize it would be a big deal. That's OK. Oil leak near the turbine section or other hot parts of the exhaust could be a big deal, just figured I'd see if this was something I should be looking into.

If it was leak, yes...check into it. One drop is hardly a leak though. Oil leaks will turn into a thick sludge build up within days and be SUPER evident as to something being wrong.

or you could take it to a dealer and let them deal with it since I assume your still on warranty...

To be clear, are you talking about the darker area or just the general rust color?
