My mind is going bad this evening Ok, the turbo feed line going from the distribution block coming off the side of front of the block gets teflon tape on it and the end that screws into your turbo. The return line going back from the bottom of the turbo has a paper gasket held in with the two bolts located at the bottom and no gasket into the block. I was thinking oil cooler lines when he said coming from the motor which they do have o-rings Everything is blending in my view when I look at these threads!
