Just wondering if anyone can tell me how i'm getting what appears to be dirty oil in my intake pipes and MAS/air filter assembly. I discovered the problem when I removed the assembly so I could get to my hood latch for removal (see previous post about hood problem...). So I completely cleaned out the MAS/air filter assembly and cleaned as far as I could reach into the intake pipes. Washed everything out with soap and water. Now everything is again coated with what appears to be dirty oil again, after running the car for 5 min and taking the assembly apart again. What gives?
