I'm putting my turbo on tomorrow and if all goes well I'll be moving on to the next step: Cleaning up the mess the previous owner created. On the intake tube, just before the throttle body there is a nipple. The previous owner had this plugged with some sort of plastic cap and some electrical tape. I'm going to put a heater hose cap and a hose clamp on it. So what is supposed to be hooked to that nipple. Is it the pcv valve? Is this okay capped or should I hook it back up? Next step is the vacuum lines, but I'll save that for another thread.
