Omega General Help / under bonnet hissing
« on: 20 August 2006, 12:05:31 »
Hi to all
I have just been checking my omega over after noticing a new hissing sound under the bonnet, This is quite loud and seems to be coming from under the pleum chamber. It is more noticeable on tick over, I can make the hissing stop when i squeeze the hose running to the ICV.
does anyone know whats causing this hissing? Sounds to me like a spilt hose or pipe of some sort i know my last 2.5 omega did not do this.
Should it hiss like it does? :-?
If i have to take the plenum off how do i go about this as i have no haynes manual as of yet. And is there any gaskets/o rings i would need to change on refitting.
Any help on this would gladly recived.
Cheers NEIL
