Ok so im almost done with my emissions removal/rats nest removal. I noticed that there is still 2 hard lines going across the front of the motor. 1 is for the oil to the turbo and the other goes to the little check valve for the TID. My question is do i need the check valve anymore or can i just cap it off at the TID? If not where do i run the line to? Thanks and i did do a search but found nothing on it. So if there is a thread about it feel free to flame. Thanks

 

It's part of the PCV system. Look up how to run a catch can.

 

ok i did that for the the oil filler neck but i didnt realize that that was part of it. Thanks for the quick reply
