What Did I Find in My Intercooler Piping?

[greensto]

After taking off the piping that goes directly into the turbo, I found a black oil substance leaking into the piping. I cleaned it out and never experienced symptoms. Car is running strong. No CEL. My only guess is that my rail valve has cracked and it's leaking heated fuel. I have a 2005.5 so I have 116 bar instead of 125 bar like 2007+

What do you think it could it be and what can I do to fix it?

its oil, or oil residue.....it happens, a little bit is ok and normal, a lot like a pint or a quart may be something you need to look into

It wasnt a lot at all. Probably half an ounce or so, but I def didn't like seeing anything in there. So it has nothing to do with the rail valve?

i wouldn't worry too much about that, when i did my FMIC, i had some oil in my first pipe.....re-used it to make my silicone couplers easier to work with haha
