Hello guys

Has anyone come across a low level split hose? The subframe and front of the exhaust (where it runs at 90 degrees to the length of car) look like they are getting covered in a very light misting of oil.

And there is a whooshing noise at 2500 -2800 rpm. So I am wondering if there is a lower hose running to the turbos which has split and is spraying a light misting of oil. Turbos are clean and dry.

Changed oil cooler and o-rings so the source is lower down.

Many thanks
