Hello all,

I realize that this is one of those questions that have been beaten to death, buried, dug back up, resuscitate, beaten again, and reburied but I have a question that I have not been able to find the answer to.
I realize for a single catch can setup, the general consensus is to route it from the non PCV VC vent to the can to the preturbo intake pipe. My question is, can I route the "out" line from the can to the throttle body pipe? My thought is, if for some reason not all of the oil and crap is filtered from the air, then it won't get run through the turbo and stuff and it will instead be fed right into the intake just like it was meant to do from factory. Another reason that I am asking is I feel like since the lines would be coming from a similar location, it would be cleaner looking.

While I am at it, I believe that the vacuum line for the BCS is meant to go to the intake pipe as well, can I do the same with this line?

Thanks all!

No. Everything post turbo is pressurized. Doesn't work that way.
