vz sv6 blue smoke on start up

[kiwi nz]

Hi

Can you please help me out? I've got a VZ SV6 Commodore and on start up it produces blue smoke from the exhaust. It doesn't do it all the time, only when it hasn't been driven for a few days.

I've taken it to the agents but they couldn't diagnose the problem since it wasn't doing it when it was with them (I left it with them for an entire week).

Any suggestions? The vehicle is still under warranty.

Thank you

blue smoke usually means your burning oil

Why does it only do it on start up? and wouldn't it do it all the time? Thanks

it may be likely that one or more of the valve stem seals are worn out....

I agree with christina, but it sounds unusual as this problem usually arises on high mileage engines and your engine should still be relatively new.
Try asking 'Dr Bob' in the pub section under the heading 'ask the holden technician,as he is pretty good and might have a better answer.

i have just done 60,000km. If its the valve stem seals wouldn't it do it all the time and the agent should have picked that up? would it show up if they put it on a scanner?

i'm going to take it back to the agent this week, is there anything that i can ask for to confirm that the stem seals are worn? thanks

I have seen a few cars in the past less than 2 years old blowing smoke because of worn rings due to owners thrashing the crap out of their little 4 cylinders.

Could be a fault or anything. Should get it fixed under warranty. It's an easy job to fix if it is the stem seals and it definately seems like it's at fault.

Have you owned the car from new?? Might have been a dealer thrash-mobile or driven badly.

But yes you should take it to your dealer although they will prolly want you to leave it there so they can start it cold and see for themselves.

i've had the car since last year. the plan is to leave it with the dealer next week again maybe this time it might play up.

If it's the stem seals at fault, it would happen at every cold start.

is the oil overfilled by any chance?

[AttaBoy]

Some how quite amount of oil is entering the combustion chamber. It could be down to worn piston rings to valve stem, overfilled engine or running too lean which I doubt it.

Do you park it on a hill by any chance? I've left my SV6 Parked both uphill and downhill in driveways overngiht and had it puff blue smoke.. In normal conditions though(flat road), its never done it.

Hi guys
I checked the oil it was fine. it was replaced about 4000km ago.

the car lives in the garage and only comes out every few days. My driveway is on a small slope.
I started comunicating with Dr Rob from the Pub hopefully he'll be able to find out or give me an idea of what the problem is.
thanks

I had my valve stems done at 100k, not a big issue but I didn't want to see blue smoke every morning. Now it blows a little black smoke in cold starts, considering the engines over 220K, so thats pretty normal.

find any fault for this?????. my bro's berlina(vz) does it. had me worried so ive been checking my sv6 everyday for the last week and hasnt even blown a puff of smoke.

there seems to be a descent amount of it coming out of the berlina. about 3 seconds worth

Not a Holden, but I remember now seeing a little bit of blue/black smoke coming from my Mum's 2002 Lancer after taking off. It's only done 50K. I think it's simply due to a tiny bit of engine wear and that very small amount of oil leaking into the combustion chamber overnight. No big deal. I wouldn't worry about it unless there is a cloud of blue smoke when you start it up like my brothers VK does lol.

Hi guys
I got my SV6 back from Holden, they finally saw the smoke coming out of the exhaust. They are not quite sure what it is, they are waiting to hear back from the Holden technician and they said they would get back to me next week.
Thanks for your info and ideas. I'll let you know next week once I hear back from the Holden technician.

Im having the same issue on a 2004 vz v6 ute 140 000km.

On a cold start up it will blow a small amount of back smoke for about 1second but after that the flow goes clear and normal. if it is valve stem seals then its not a big problem. My honda xr250 did it, replaced and re seated the valves no more smoke. (Was a rebuild so do it right the first time,)

Anyway it does not accur all the time just if it sits more than a few days. Car was originally a city car and the previous was a bit heavy footed but neglected to take care of the car such as new oil and filters, gear box was said to be overdue by a very very long time etc. but all that is serviced and engine runs without a glitch.

Black smoke is fuel, possibly a leaky injector.

You turn the car off and the pressure in the fuel system bleeds through the leaky injector and sits in the cylinder till you start the car and is burned up quickly resulting in black smoke.
