Title: plenium removal
Post by: vauxsull on 26 February 2008, 19:13:38
Is it a simple enough job to remove the plenium chamber on the V6?
Anything to watch out for or avoid un-bolting?

Straightforward enough.  The following blatantly robbed from a 'how too' on here....

Remove the EGR valve electrical connection, and the RH knock sensor connection. Remove the connection from the rear of the Idle control valve on the passenger side of the plenum, and remove the valve from the car. Remove the rear multiram actuator connector, at the rear passenger side of the plenum. Also remove the vaccum pipe to the rear multiram. Remove the 4 breather pipes from the rear of the plenum. Remove the 2 bolts on the passenger side of the plenum, holding the cable tray to plenum.

Undo the 24mm nut holding the EGR “wiggly” pipe to the EGR valve on the drivers side of the plenum. Unplug the throttle position sensor on the front of the plenum.

Where fitted, remove the throttle cable and cruise control cable from the plenum.

Remove the 4 plenum bolt caps (if fitted). Using an E12 torx socket, remove the for plenum bolts. Carefully lift the plenum off and place clear of the vehicle, ensuring that you collect the 6 plenum O rings.

Place suitable rags / kitchen roll into the 6 inlet ports now exposed, (the “trumpets”) to prevent any foreign objects falling into the valves.

would it be possible to gain access to the dis pack now the plenium has been removed? also what is the multiram actuator?

It would probably be better if you have a look through the various 'how too's' in the maintenance guides section.

One such guide I found was this...

It details with piccys most of what was briefly explained above.

I think there is one explaining dispack removal as well....   :y

You can get to the DIS pack without removing the plenum.

With the plenum removed the access is better. So is the access to the plug leads and spark plugs.
