D16z6 hissing :s

By SmoondaSi
- Wed Jan 26, 2011 4:46 pm #235537 im on my second d16z6 engine and have noticed that the intake is quite noisy, it makes a sort of hissing noise kinda like a dumpvalve but its constant and gets louder when you open the throttle body. its been the same on both z6's an i was just wondering if this is normal or weather summits wrong? any ideas?
