yeah, where your hand is, slightly to the left underneath a little pipe has come off... my VT II S did it once when the LPG backfired

Ive been running a 70mm TB for a while and she gets a whistle up here and there too.

common fault on these, the vaccum hose at the bottom of the throttle body has come loose. L shape peice directly at the bottom of the t/b and the hose runs under the inlet manifold to the other side. there was a revised hose that can be sourced from holden or otherwise just glue the joiner back on.

common noise for the ecotec motor nothing to worry about.

throttle bodys if you put one on after market will have a slight whistle to them almost like a turbo or if you run your power wire and speaker wire to your system together, that sounds like a vacume leak

[joelrobo84]

it is just air when the butterfly opens up m8

[RiCkstaaaa87]

IMO i wouldnt fix it, i reckon it sounds awesome! lol

[dtm0608]

yea mine had a noise like that, ended up being the vacume line from the throtle body on the underside that goes to the brake booster.

[jameslinton50]

i agree but also cud be a vacume leak somewere

Are you talking about the whistle kinda noise everytime you rev it ? mine does the same thing pretty sure its normal.
