I am pretty sure the coil pack that was in a right state was the passenger side Raff 2-4-6 bank

[Koomorph]

No worries mate - you've been uber helpdul as it is!

Thanks Daz - do you think this is the likely culprit then..... ? You thinking of making a trip down south anytime soon....

I'll get another fry-up on the go.... 

[Darth Loo-knee]

The distance I will travel for a fry up

Not at the minute Raff, but I did tell you at the time that it looked breaked and to keep an eye on it

[Koomorph]

Right ... a few more questions before I decide the course of action....bear with me chaps!

1) The coil packs were both very oily when they were removed a month ago - the rubbers that go over the plugs were pretty shot... I doubt much has changed in a month, so by removing both packs (apart from checking for water) - I doubt I'm going to find anything different than -  slightly oily packs with worn rubbers.... So should I just try to get hold of a second hand unit to test to see if the fault is rectified (rather than spending £100+ on a new one!)... ?

2) What part of the scuttle does the water leak in from? Centre? Centre Right? Above bank 2-4-6?

3) I'm guessing it couldn't be a spark plug? As these were changed last month... ? Is that at all possible?

4) If it's not the coil packs.... (i.e... no water, changed coils... and still misfire) - should I go down the injector cleaner route? Or anythting else first?

5) If problem is still there.. I probably need a session with someone with a tech2... Who is the nearest in the South East to my CR2 postcode.... Kevin Wood?

6) Is the ONLY thing that can be damaged from a misfire is the cat through unburnt fuel? My dad needs to do at least two short journeys a day (a couple of miles)...
Is that gonna develop/casue more problems...

Thanks again!
Raf

1/ If the coil packs are less than perfect as you and Daz say (especially the 2-4-6 side) then that's a good place to start. Daz even warned you about this one so I'll bet it's money that's not going to be wasted, whatever happens. Oil in the wells will do the same damage as water ie. damage the coil pack

In reply to no. 2, my scuttle leaked where the two halves joined, which is just above where the end of the coil pack is on the passenger side bank (the other bank was dry). The design of the scuttle is such that it isn't supposed to leak, but in practice, if you pour water on the windscreen, little drips get through the gap and over time will fill up the spark plug recesses, despite there being a rubber seal on the coil pack. I sealed the gap in the scuttle with a tube of bathroom sealant and hopefully have cured it

Oh, and make sure your scuttle drain on the passenger side is clear (by the pollen filter) - mine wasn't and I've still got the scratched forearms to prove it 

3/ If you're taking the coil pack out anyway, have a look at the state of the spark plugs, can't do any harm, although I'd be surprised if they're in a state being so new

4, 5 and 6, don't know - someone more experienced should come along soon...

HTH, Jon

[Koomorph]

Ok, thanks JC... very helpful mate... 

Are the 2.6 and 3.2 coilpacks interchangeable... (if I'm gonna get one/two from a breaker initially to test)?

Yes it is - PART # 9118115

Just to add.... As with JC's, mine was leaking at the scuttle join, but also through the hole for the central wiper shaft (thanks to Tunnie  ) - I sealed both the top and underside of the hole with silicon bath sealant, and that fixed it fine - did the same with the other wiper hole, as that is above the power sounder.
I twould appear that the padding that normally seals the wiper shaft to the scuttle hole comes away over time, and water creeps in..... I proved it by pouring water down the windscreen, and watching it pour through both places 

As for question 6, repeated misfiring caused the emissions light to flash (indicating to lay off the gas as the cat was seeing unburnt fuel), eventually staying on solid. Changing the coil pack made the light turn off after 4 starts, and the codes 0300 and 0304 cleared after a few weeks on their own 

[Rockhampton]

Just been clearing out the garage, and came across my old coil pack... here are a couple of shots so you can see the water damage.... the water rises up the boot, and finally corrodes the metal on the coil unit, finally destroying it 

[Koomorph]

Thanks for posting those - good to know...

I've found a couple of sellers on ebay that have 2.6/3.2 coil packs from miggy's they've broken - but they're used and no guarantee that they are ok ... apart from... "Well the car was runner..."  ..... £40 inc delivery.

How much are they new from VX? Don't have a trade or club trade card....

[jonnycool]

If you pm andyc on here he's a parts manager for vauxhall who can send you parts at trade club prices. I've used him before, he's very helpful. Don't know how much coil packs are, over 100 quid I think

Yes, I seem to recall the rack price is around £100... I'm sure someone will be along with the TC price soon, but Vaux-World on eBay were selling them for about £70 genuine part 

[Koomorph]

Blimey!! And they're selling cam cover gaskets and o-rings - full V6 set for about £18!!!!!

Surely that can't be genuine GM... http://cgi.ebay.co.uk/Vauxhall-OMEGA-SAAB-V6-CAM-ROCKER-COVER-GASKET-SET-NEW_W0QQitemZ370107027655QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item562c1910c7

No coil packs though...

[Koomorph]

I'm still trying to source a coil pack at a decent price, but thought i would ask what is the possibility that it could be one of the injectors causing the problem? How rugularly dothe injectors on the omega fail or clog up? I ask becuase my dad said that when he drives and applies half or more throttle, the missfire dissapears and car runs fine! I'm wondering whether this could signify an injector problem and if it would be an idea to get some good injector cleaner in there first to see if that helps solve the issue....?

[Koomorph]

Any.. thoughts on the injector cleaner side of things chaps?  :-?
