I have been having this problem with a leak of what looks like oil, But I check the oil level and it is fine. There is a black tube that runs in behind the intercooler on the drivers side and it has oil all over it and is leaking,also could a problem like this cause bad gas mileage, somebody please let me know what to do I have no idea what is wrong!!!!!

Thanks

 

is it the black pipe that runs under your motor and connects to your intercooler and turbo? If so then its not a big issue you just need some catch cans. its blow by oil

 

yeah it is the black tube by the intercooler and turbo, does it just start because it has not done it before

 

its blow by oil from the pcv valve, and the crankcase ventGet some catch cans and it should handle the problem. there is a thread that shows you how to make a catch can for 20 bucks on this site. or you can go buy some

 

While you're at it pull the pipes off and clean them out. But a catch can is in order for you
