sup guys, just installed a 5857 turbo on my car and the first test drive was fine, then today i went on a second drive for about 40 miles, and close to the end the car started smoking out of the tail pipes. not a huge amount but enough to smell and see(definately oil). im running a -4 braided teflon feed line from the stock supply location and a g body parts new drain line(the black nylon braided rubber one with barbed fittings on both ends). so im thinking maybe the -4 feed line is just a hair too big and was considering stepping down to a -3 or getting a .065 restrictor, but wanted to get everyones opinion on what i should do? im pretty sure its not the drain line backing up cause its a -10 if im not mistaken, makes a sharp 90 after the flange but its not kinked just barely starting to oval. thanks for any input already pmed patrick since hes the resident guru but wanted others opinions what theyve done.
