Look in your first pic

The lead with the red thing on is plug lead no 1 - pull one of those up. And same for other side. Look in the holes for oil. this is essential.

In one of your later pics it looks oily in the camcover area, which would support my theory... I bet one of the gaskets has let go and destroyed a plug lead(s).

12 isnt listed, but i think its the start of sequence code  :-/

144/145 are imoboliser errors so not going to be cause running probs.

Best i can do.........sorry  

Im sure a v6 expert will be along when they've sobered up  

[JamesV6CDX]

TD you slow git, I posted this info 6 minutes ago

Edit - one glass of wine all evening, for me  

Codes 144/145 are immobilisor related, and unlikely to be a cause for concern.
Code 12 is the start of diagnosis - no cause for concern at all

So there are no tell tale codes

The "shaking" of the engine you describe does sound like a misfire, I'm prepared to bet it's DIS, leads, or plugs.

The first thing to try is to remove a lead from each bank (not a plug yet, just a lead) and look for oil IN the plug wells.

Off for a bath now, but will try and check again before bed. Don't worry, you'll get there

Thanks James! Checked plugs from left side. They are clean and OK. Can t get access to second side, but I can see some oil on them, so that may be the reason. Oil level seems to be OK, and it was topped up last time few k miles ago, so it must be very very small leak. Is it expensive repair? And will it help if I will clean plugs / replace them? Is replacing that gasket difficult / exp?  

[Entwood]

Paul .. the problem is ... if the rocker cover gasket leaks - common problem if the breathers get blocked - the oil can leak into the plug wells and slowly fill them to the point that the HT leads are contaminated - this can cause premature failure of the leads - which then gives a missfire.

It is unlikely that a quick clean up of leads / plugs will solve this unless you are VERY lucky, if the leads have deteriorated they have to be replaced - not cheap either  ...

Then its gasket replacement and breather clean to prevent recurrence .. there are HowTo's for both in the Guides section

Hope that helps a tad .. not the news you wanted though ...

[Paul]

Right...  

So can I get access to other leads (dirty ones)?
How can I check breathers?

Will that leak get any worse / further?  

Have that problem for last 2k miles, so leads should be still OK..?

And do you think I will be able to replace gaskets myself? If not anyone know someone cheapo..?

And last question.. Can I still drive my Omega on short distances (to and from work 4 miles one way)?

Thanks for all your help!

Gasket replacement

Leak won't get any better .. but might not get worse, after al, it is now relieving the crankcase pressure and that shouldn't get any higher .... but I wouldn't swear by that !!

Can't find a howto on HT leads but this is on plugs themselves ...

If the car runs .. its driveable .. (unlike mine at present ..  ) and all those jobs are doable yourself...

HTH

[Paul]

Thanks for that.. Problem is I just cant afford any repairs (especially these expensive ones..) this month and there is no chance i will do it myself.. I will make only more damage..  

So can i use it for next month then?

And why it is like that only when car is cold? Why it is OK, when it is warmed up!?

[Entwood]

I run out of knowledge now .. but it is possible that as the damaged plug/lead ( if that actually IS the problem) heats up the metals within expand, so making good/better eletrical contact and it starts to fire properly ??

Only a theory ... I'm sure a grown up will pass by and correct me soon enough ..

[JamesV6CDX]

I'm a bit mislead - because your initial post states the problem occurs when warm, as well as cold.

Either way, if there is oil in the plug wells, and if the car is misfiring, you should not continue to drive it until it's fixed.

The reason for this is because if you drive with a misfire, un-ignited petrol is entering the catalytic converter and will soon kill it. That WOULD be an expensive repair.

[Paul]

I'm a bit mislead - because your initial post states the problem occurs when warm, as well as cold.

Sorry James, problem occurs on cold engine (warm as well sometimes - its like that just for first 20 miles / 10 in traffic, but temp gauge is on 90 after 10 mins). 2 days ago it happend only on warm (on a return trip, 60 miles). But next morning again - only on cold. Mechanic took a look, but he said he cant see any 'big leaks' and 'small leaks are normal for these engines'  

Ive been advaised that all I need to do is replace plugs / leads or iit can be blocked filter (fuel). Or just some fueling prob.
Im so confused now.. And I need to deive 1.6 Astra again!  

[Paul]

anyone?  

[JamesV6CDX]

anyone?  

Have you managed to pull a plug lead on the passenger side bank yet?

[Paul]

only two, includes one 'dirty and oily'. bought new plugs.. need to fit them..
