I removed a faulty oil line that goes from the comptech blower to the VTEC mounting block. I installed the replacement line from comptech, but now I have a problem. The mounting block side is good, and from the line to the fitting on the blower is good...but there is an oil leak between theat gold piece and the blower now. Is that just a nut that needs a certain size deep socket to re-tighten? Please advise Thanks!
