Has anyone changed the dispak...it seems impossible to to get to ...I have been told by a garage that that the car needs to be up in the air and can't be done at the roadside

It seems that the whole of one bank of the V6 needs to be removed to get to it...or is there any trick?

I don't have a garage so have to do it in the road outside....I have been quoted £190 plus parts to do the work is it worth it or can I do it myself?

[Markie]

Your garage is talking nonsense. Car can be where ever - as long as its dry.

This can be done with perseverance and slim hands / proper tools, by you !!

Need to strip the skuttle and possible the plenum ( engine top) and mark everything you remove. Dispack access at back right hand side of engine as you look at it. You do NOT need to remove either bank  :-?

£190 is outragous, its also a circa £80 - £120 part at trade price dependant on car.

Do it yourself - we can assist if you get stuck   and yes plenty, including myslf, have done it.

Recently I had the plenum off (and scuttle) and the injector cage out and even then I could only just see the thing never mind get to it...how the heck do you get to the torx screws to get it out ?...there is absolutely no room whatsoever...do I need to put it on ramps first?

Changed one a couple of nights back.
Remove the wipers and scuttle.
undo servo vac pipe from plennum and move it as far forwards as poss.
move vac pipes and breather pipes out of the way
may help to un plug the injector cable (big connector around coil area)
Unplug LT connector
Unplug HT leads and lay to one side...pass. bank ones are short so wont move completely out of the way
Undo the 4 bolts using a 1/4" drive 8mm socket.....your torx sockets are likely to be too big and will get stuck
When free you might be able to get the coil out between wiper motor but if not then slide it along behind breathers etc and out by servo.
Replacement is the reverse as they say, use the old coil to identify cyl Nos when replacing the HT leads (leads have numbered ident rings and coil has numbers in moulding.

Takes about 20 mins to do, dont force anything or flex the HT leads too much.

No leave it 4 wheels down, theres no need to be underneath - although vx aparently say its gotten from underneath.Trust me wiggle your hands down ( follow one of the ignition leads to make sure you get to it) Obviously disconnect battery as well.

Its done by touch rather than sight - so you wont see it. You need a very compact ratched with 3" and 5" extensions for the 4 torx bolts. It is fiddly but doable.

Dont be paying £200 for a job plus parts that you can do in a day easy.

And ....... of course you'll need a large box of plasters for when you finished!!    
As Markie says it's all done by touch/feel.

Just called Autovaux and they say that I won't know which part it is until I remove it... even though I have the engine number....whats best to do buy all three

P.s. I do have EPC but it won't run on my new PC with Vista...Doh!

Yep there are 3 different dispacks. One for early, middle and late omegas...its best to remove your old one and quote part number  

What sort of prices were they quoting? they may not be the cheapest.

[Marks DTM Calib]

It will be one of two as given the age of your car, it wont be the early vertical one.

If you pop the scuttle off you should be able to see the DIS pack, pop the LT plug off and look at the shape of it.....thats the give away on which one it is.

75 + vat. 91 + vat and 91 +vat...I have a trade club card and I notice at Vx there are 4 models of dispak ...the last and cheapest for the 2.6/3.2 V6...as it happens every time I have been in this situation before my 2.5 has always used the 2.6/3.2 parts...can anyone tell me from the EPC?

BTW where may be cheaper?

[Marks DTM Calib]

Its one of these two....the later 2.6/3.2 are coil per plug so much cheaper (coz they only do 3 cylinders):

Rectangular connector

or

Oval connector

[a2reed]

OK I am going to go for it and do it myself....when I had the plenum off the other day I noticed it was the curved connector so I will order one and get stuck in...many thansk for all your help


Matchless reckons 20 mins..!!! bet it takes me longer ... I reckon about 6 hours!!!!LOL

Finally ... what else should I order at the same time to change while I am there?....Rocker cover gasket etc?

[a2reed]

in the mean time will I damage the Cat If I drive it lumpy for a couple of days ?.... I assume it will be chucking petrol down the exhaust

[bob.dent]

and yes plenty, including myslf, have done it.

.........and I've seen the skin missing from your hands to prove it!!
