I have a 1998 2.0 Auto Estate, recently I have noticed that she is smoking slightly on start up along with a little tappet noise. Now Ive carried out a full service and changed the oil to Castrol Magnetec 15/40 as recommended by my vaux dealer, however when I changed the plugs (1st time since purchase - 8000 miles) I noticed that one of the leads was slightly damaged (tapped up with electrical tape) and Im not sure if this is contributing towards the smoking as it smells more like burnt petrol than burnt oil. Also the smell wears off within a few hundred yards as the engine warms up slightly.
Is it possible that this is caused by the damaged lead or do you think that this is possibly down to her age and the fact shes covered 100,003 miles.

Unless there's a noticeable misfire I would have thought the plug lead is not the problem, although it'd be worth changing it in case it catches you out sometime.
Smoking only on startup is ususally oil seeping down past the valve stem oil seals. A little collects in the cylinders when it's parked up and it burns off when started.
Not really worth worrying about unless it gets excessive IMO.

Indeed.... is it white smoke?

I recommend Vauxhall's own semi synth 10/40 oil. Dirt cheap on trade club as well ;)
Don't worry about the mileage, just nicely run in :)
Not sure on the smoking - the ecotec engines do produce a lot of condensation out of exhaust, is it more than that?
When warm, is it OK?
Ticking/tappet when cold may be exhaust manifold gasket...

Well thats what I would have said, however its def not blue smoke and Im not using oil which makes me think that its fuel burning. It also appears that the tappign gets louder when accelerating after cold start up but like I say it quietens down after a short distance which again posints me towards the lead and shorting??

I'm tired and can't type very fast whilst laying in the bath drunk...

Does it start easily without a misfire, particularly when hot?
Fuel smell could be a leaking injector dumping a bit of extra fuel into one of the intakes. This might smoke a bit as the catalytic converter warms up and burns it off.
Depends if the smoke is white, black, grey or blue.
A teaspoon of oil will generate a lot of smoke on startup so you wouldn't necessarily notice the oil consumption.

No, but I could take some posts away from you.... ;)

No it doesnt missfire at all, infact it runs great when at operating temp. The smoke I should say is white/grey and only does it when cold. If I drive her during the day then there is no problem, its only when left overnight.
Ive also had issues over the last couple of weeks with her stalling whilst slowing at junctions but I think that was down to some bad fuel I got from an Asda store and I havent filled up since, however im changing the filter in the morning and adding a dose of fuel cleaner to sort that out.

Also check for air leaks, and clean up icv

Ok Thanks, will let you know how I get on.

Do consider that the air injection system should operate for a minute or so on start-up....

Sorry it won't happen again :-[

Thanks all, checked your recommendations and cant find anything out of the usual so shall put it down to age and the previous owner not looking after her properly >:(
My other issue of stalling as you slow down has reared its head again though. Thought changing the fuel filter and putting in some fuel cleaner as well as a fresh tank of juice would have sorted it and to be honest thought it had, however its started again on my way home from pontefract. Happens as you reach about 5-10mph but starts straight away when pushed into nuetral and turn ignition. Cant see whats causing it as it only started after I put in a bad batch of fuel.
Do u think I should leave alone until ive had a couple of fuel refills and the cleaner has had more time to work or do u possibly think their is something else causing this????????
