just started my car this lunchtime and quite a bit of grey/blue smoke came out of the right hand exhaust pipe - enough to notice, but it stopped after about 10 seconds.

it was last driven last friday morning and i remember reading somewhere that due to the design of the engine - if not used for a while some oil WILL seep past the pistons and burn up upon starting - right ?

Someone tell me i'm right :?

Only just got it back after its 80 thou km service and a new clutch - not 8)

i will watching it like a hawk now - :eek:

Happened to mine last week after a week or so of unuse.

Not seen any smoke since, so your explanation sounds good enough for me!

You can also get some smoke on start-up if the last time the engine was run it was only for a short while, say a couple of minutes eg moving the car out of the garage and then putting it back in.

I wouldn't worry about it.

My old 3.2 1988 did this when I got it at 89000 to 120000 miles when I sold it.
My 1997 993 Targa did this from when I got it at 20000 and still does it occasionaly at the current 41000 miles.

Its a flat six and the oil sits around the valves/guides when the engine stops, dependant upon the valve wear and the individual valve position, a small amount of oil seeps into the cylinder and is burnt off when the engine starts. Even new cars do it.
Start to worry when its a destroyer-like smokescreen every day that takes minutes to go away and has the neighbours in fits of laughter.

Thanks for your reply Stevo.

Westyman - I spoke to my mech who also said that the james bond effect can be caused by starting the car,driving it for a few minutes and then stopping the engine. upon re-starting later the smoke appears.

Thanks to you all.

Thanks Warren,

I'm sure it is due to the fact the engine is on a cold start fuel setting which uses lots more fuel than when the engine is warm and some of the fuel is left lying around in a similar principle to the puddling of the oil.

I wouldn't worry unless it starts happening frequently.

Oil burns blue, petrol burns grey. If it does happen again, check what colour it predominately is.
