I have the strangest issue with my Evo. When on boost, I get a burning oil/oily smell in the cabin. This only happens on boost and you can smell it through the vents. It is faint, but noticeable and happens around 5PSI and up.

I am not smoking, consuming oil, and the intake is dry.

You know what?!! As I type this I realize my catch can is VTA with a breather filter! I wonder if this is my issue?

I know there are people on here that cap off their intake and use this method. Are you experiencing this as well? Kind of makes sense the more I think about it, but I would like to make sure.

What do you think?

 

My breather valve was VTA so I ended up tapping it back into the intake and the smell was gone. It is definnitly you breather valve
