I'm newbie here, I was wondering if anybody can help me figure out this knocking coming from inside my motor. First of all, let me tell u about my girl. She B16a2 fully build, boost on pre-tune base map at 10lbs rite now...I want to break in my motor first of all before I hit the dyno. While driving her crazy, I started hearing knock coming from my motor. First thing I thought was (could it be) and my car shut off when I take my foot off the pedal. I pulled over n had it tow home. The next morning, I went to started her up just to heard the knocking noise, n i knew it was my pistion or bearing. But I went ahead n check it anyway to make sure. But I did a lil research n see some post about their civic having this knocking sound coming from theirs valve springs. I thought back to this dude, who gap my dual valve springs. Anyway, sorry for the run on here, but any help would appreciate here. Thanks
