I just installed some cheap 'ole short ram on my del sol (d16z6) and, the first thing i noticed was when it was at idle it made a whine. The intake tube wasn't really built right so the crank case tube is still pluged in put down at the bottom right next to the valve cover it is kinda kinked. Why does it make a whine nosie? It does it even when i'm driving but let off the gas, should i not worry about this?
