Title: And the tick goes on
Post by: 3.2 paisley wagon on 26 February 2011, 20:48:59

Hi Chaps, Still getting a ticking/clicking noise coming from back of engine bay.  Took to local garage and car put on 4poster. Mechanic reconed exhaust leak from either manifold gasket or front pipe to manifold gasket.  Bought both from my local Vauxhall dealer and booked car in to my local garage for fitting.  On my return to pick my car up the mechanic advised they had replaced the front pipe to manifold gasket but on checking the manifold one found it to be intact so didnt replace.  Although a bit quieter the ticking/clicking noise is still there.  Started the car from cold an hour ago and all was quiet. A few minutes later the tick started.  On going over with my trusty stethescope i notice a loud tick from 2 places.  One is the pipe coming from the charcoal canister to the PCV and the other being the air feed pipe going into the plenum.  I have had a Purge control valve go faulty in another car years ago which was a similar noise to this but unsure.  Can anyone advise what feeds the air intake pipe on the rear of the plenum? (of the four pipes going in its the 2nd from right)

Why not just pull the electrical connector out of the purge valve and see whether the tick goes away?

Can you explain how to get to it?  Ever worked around a 3.2?

not a lot of space behind there, do i need to remove plenum or grille below wipers to get access?

Plenum & scuttle off will make it a whole lot easier

What you are calling "the grille below the wipers"

Ah right.  Is there any way of testing the pcv without unplugging it?

Scuttle removal similar to facelift http://www.omegaowners.com/forum/YaBB.pl?num=1285581852/0
If the PCV wasn`t working you would get a P0443 code and the EML light but it may be OK whilst possibly being the source of the "tick"

Very slight rough idle too at times.
