I have 02 with aftermarket intercooler tubes. There is this oil gunck that builds up. From what i have read its the engines blowby gases that contain oil and when it goes through the turbo it tuns to this black oil stuff that is hard to get rid of. My fear is that my turbo is gone but i do have good boost pressure so i dont think that by turbo is bad. I also think there is some in my TMIC.
So what can i use to clean this crap out. I need something that will be safe for the tubes and TMIC.
