Helping a friend re-install engine on 1986 GN Where does the oil supply line for the turbo connect. It it a hard line about the size of a brake line. Does it originate at the oil pump at the front of the engine? Also, the drain back line that goes into the top front of he block. I cracked the corregated stainless return line. Any cheap ways to fix this or use another method. Even a brand new one is going to be nearly impossible to install since the whole front cover is already on the motor. Any help would be appreciated. Thanks Mark
