Ok I have a triangle shade of brown on the right front of my intercooler. It looks like it could be a leak or oil. But i would not think there is oil in the cooler. Any ways it looks real weird, i tried to hose it down but no luck. Any ideas guys? Would a intercooler leak cause this, heres a pic, you can kinda see it to the right top of the cooler. thanks guys I had debated doing a boost leak check but the car has only 1200 miles on it. thanks again

 

The picture doesn't work.

 

can i email the pic to your, I just hooked up my boost gauge and it goes to like19 then falls to 18 like normal, so the leak cant be big. Just look weird that its there.
