Newb question.

Ok this is a question thats been in my head. I see some turbos that have what looks like a vacuum line plumbed in to the inducer. On my car my turbo does not have a vacuum line. Why do some people have it? Is it important to have. My turbo is a te45a if it matters. Thanks

That is usually plumbed to the valve cover to evacuate the crankcase pressure. Most people plug it off so the turbo doesn't suck in oil.

And it a factory thing. Usually done on stock turbos and maybe some ta49s..
