I have my oil line tapped underneath the intake manifold, I searched and found everyone was putting the oil feed on the drivers side part of the head above the egr block off plate. I was wondering if anyone has used the spot under the intake manifold as I have, and had any probs with the setup (suffecient oil supply). I am wondering this cause im gettin rid of my junky temp ebay turbo, and buy a very expensive turbonetics t3/t4 57 trim.
