Hmm, that is a good question. I can't remember if that T is hollow or now or if it's just a junction. If it's hollow, I wouldn't mess with it; however if its only a junction, then bypass it.'91 GT said:Thanks... I have those lines figured out.
Some set ups seem to have the PCV hose going to the "T" on the driver side of the upper then from the other side of that "T" a hose goes beneath the plenum.
My question is do you have to run that PCV line to the second port beneath the plenum, or can the PCV just go to one source on the upper??
