Hi Folks
My 3.2 runs fine for 10 mins then when it heats up it goes off 1 then 2-3 cly.
There is a lot of crusty deposits at the front plug area in each V and the 2 rear plugs in each V are full oil. I presume it gets worse as it warms up due the the oil vaporising and getting into the coil pack. Also the viscosity thinning and compounding the problem.
Is this a common thing? Does anybody have a good fix for this? New gasket? If so which one?
Just got the car and I am really disapointed that its let me down so early in the ownership process. I hope I can fix it and start to enjoy it again!
Thanks in advance folks!

Camcover gaskets deffo need replacing and possibly the coilpacks. Also new spark plugs http://www.omegaowners.com/forum/YaBB.pl?num=1152564281
-
ok, thanks!
I take it thats a common one then? It doesnt look like too much of a bugger to sort, access seems ok to remove all the gubbins.
Thanks again.

This is a very common problem. It is very important to clean the breather system when you do the gaskets. This will prevent it from happening again. :y

Hi Folks
Ok, I did the strip down today and ordered the gaskets, o rings and plugs.
Do you think its worth getting 2nd hand coil packs or going for new ones? I dont know the price difference but would appreciate your views on best practice for a long term solution!
I dont want to be stirpping this down again soon!
Does anybody know where the best/cheapest place is to get new/used coil packs?
Thanks

OE? :-/ They're dear but work.
Pattern don't last, they go hard & then you're back to square one :(
-
Yeah OE, I am following the guide on this forum.
Whats the crack with the coil packs then? OE also or good used part?
I hope this sorts the problem, could it be anything else?
-
Vauxhall Coil Packs retail are approximately £105 for Cylinders 1,3,5 for 3.2.
Same for 2,4,6.
Trade Club price approximately £80 each. :y

I suppose it depends how much you're paying for a 2nd hand coil pack, but they do say that you're better off with OE coil packs too instead of pattern. Plugs swimming in oil is often the cause of a misfire. ;)

To be honest the first time it happened it the plugs were swimming in oil. I cleaned it up and it ran better for longer.
I assume that although there is no oil in the wells now the reason it still goes off clyinders after 10mins is the damage the oil has done to the coil pack(s)???

Might be worth changing the plugs first, but the likelihood is the oil has damaged the rubber boots at best.

Excuse my ignorance but is it the oil vaporising as it warms up that has damaged the coil packs?
I dont know how these things work so I am trying to get my head around why I am seeing this problem and how to solve it. I am not very mechanically minded so please bear with me!

Well oil and rubber don't get on, it eats rubber, so the rubber weakens and let's the spark escape, heat also a factor as it warms up at that stage. May also see some cracks in the plastic of the coil PAC itself, fubar if so.
Could do a pedal trick to confirm a misfire code. See paperclip test in maintenance section.

I have just heard from a mechanic friend of a friend that a fault in the coil packs can spike the ECU and cause terminal damage.
Is is true? I am reluctuant to spend a couple of hunderd on parts just to find the ECU needs replaced!
Is nothing simple with the Omega! I hope I have bought the right car! Begining to wish I had gone Audi!

You wont get the support on the Audi forum that you'll find here.
To answer your question, no, imo. But plod do tend to bugger about with electrics alot, there have been some 135 bank unexplaned miss fires on the 3.2. and 2.6 But first port of call has to be coil pack i woukd think?
idealy borrow a known good one, maybe from a member here?
-
Lol Audis can have problems of their own. I recently bought and fitted a 2nd hand coil pack - has given no problems. When you do the gaskets - make sure you get the breathers cleaned too - then you'll have no more bother with this! There is a guide on this site how to do it.
-
Thanks to you both! I really like the Omega, its a bit different and I love the rwd, uncompromised handling.
New OE coil packs and plugs just been deliverd to work. If the gaskets (OE) are there when I get home I should have it back together tonight.
Fingers crossed!
Thanks again!
Oh, and I will make sure all breathers are cleaned out!

Thanks again
