Vapour/light white smoke on start-up

Post by **simonc** » Tue Dec 09, 2014 12:20 am

Morning gents,
Yesterday I started the car and realised I'd left the house keys on a table outside. I got out, got the keys and as I was going to get back in I noticed some smoke/vapour from the exhaust.
The choke was on so the engine was revving a bit and it was a fairly cool morning.
The smoke/vapour was a whitey/translucent colour (no blue/black) and although not masses of it, there was enough to get me thinking about asking this question.
I thought I'd wait a bit and see if it disappeared which once the engine was warm (1 block on the temp gauge) the smoke/vapour seemed to stop. When I drove to my appointment there were no problems and all seemed well.
Is this vapour/smoke a normal thing or is a sign of something happening?
Your direction and advice is most welcome, thanks, Simon.

Sorry - just to add that this morning I kept an eye on the rear view mirror as I drove off and there were no huge plumes of smoke following me as I drove down the road where I live.

DONT PANIC

in the words of hitchikers

Standard cold morning H22. get used to it. its a dirty old engine and it kicks out loads of condensation on cold morning.

I asked the exact same question many years ago.

Just condensation.

My Prelude did it, and my Legnum looks like it's leaving a smoke trail for miles with the amount of condensation that generates!

Haha - was going to ask the same question. Been using the lude for the commute this week and notice it does smoke a hell of a lot for the first 15 mins or so (white smoke)
Thanks for the clarification
