Oil.
I tried to clean by hand. No luck
Ran 3 tanks with stp fuel treatment
Was back in and it was spotless
Even the valves that you see
Intercooler is also full of junk
Needs cleaning a lot
I took pics but photo bucket has changed and I cannot share them
Did the fuel treatment help with the IC??? Thought I had to pull it off to clean it manually, if not thats great news.
