feed line that I could see and it was 100% dry. I took a borescope and ran it down the D/S intercooler pipe to the turbo and once I got about half way I could tell the inside walls were caked with old oil...but what's odd is when I reached the actual turbo outlet part, it looked pretty clean (bright silver in color with no oil spots...but I may need to make a good run and then try and use the borescope almost right away if I can do it without burning myself or messing up the borescope)
