My 2016 Nismo RS is leaking boost. I have sealed up the few things that were leaking- 2 intercooler pipes and the BOV at the pipe flange. Now I've got 1 big leak left. I cannot find it. I hear it. I sprayed the area I hear it with soapy water and it is not making bubbles because it is shooting out like crazy! I thought it was leaking around the bottom of the high pressure fuel pump, but on closer inspection it is shooting the soapy water towards it. I cannot see where it is coming from as the wire harness and some other things are blocking my sight and I cannot move them at all to see anything. Can the rocker cover leak boost? If so, I thought it would leak oil as well...no oil leaks at all. I've exhausted everything I know to do. I've Googled it. I've talked to my local shop over the phone. I thought someone on here might have had the same problem. I do have a FMIC, aftermarket piping, custom downpipe, and a tune. I'm boosting at 16lbs. Nothing too crazy yet.
