This is for 1985 300D Turbo California model

I found the breather hose from top of the valve cover goes to 2 places:
(1) Top of air filter
(2) Turbo intake

No wonder the air filter/housing and turbo areas are always oily.

I am tempted to connect the breather hose directly to close to ground. However, it is not good for the environment and it is against the law.

Is there other ways to re-route this breather hose to another place, like some oil separator device, etc?

Thank you
