Well, the other day I was taking pictures of my intake install and noticed something liquid on what I think is the intake manifold... I swiped my fingers through it and it was an oily color, but it didn't feel like the 15w-40 engine oil. It appears to be a puddle running all along what looks like a little tunnel right on top of the engine, in front of the turbo. Does anyone have any ideas what this might be? I have not experienced any problems with the engine whatsoever. I checked all my fluids and they are right where they are supposed to be. Please help!!
