Strange air leak
« on: 13 December 2012, 17:37 »
Hi guys

In getting a strange air leak... It seems to be from the pipe on the right just behind the manifold.

When I pull it up, the car starts to idle nicely again.

Can anyone help with wht pipe this is?

Any help would be appreciated

Cheers

Hi Guys,

Finally managed to graba  picture of my engine bay and circled where the problem lays in the photo below. If i pull the pipe up, the leak stops. It only starts again if I give the car some beans.



Can anyone advise if they ahve come across this problem before - or part numbers for this pipe etc?

Cheers

looks like a brake booster pipe to me  :undecided:
but its a different engine to mine so unless it links into the PCV somewhere...
