Blue smoke pumping out of the Boxster exhaust!

[ed22]

Hi all

When I started up my S yesterday after the storms, I was horrified to see a great cloud of blueish smoke!

As an aspiring Pistonhead, I gingerly took a bit of a sniff at the smoke and it didn't smell particularly oily. Admittedly not the most scietific test!

The good news is that it now starts cleanly again. My old elise used to have problems after a really heavy downpour,(the water would get in the engine!!) but I'd be surprised if that was the case here?

I rang Porsche up and they said it was 'quite normal; this happens from time to time'and it was 'something to do with the way the engine lies' ???!??!

!!! Is this true?!

Yes, this is a normal thing for boxer engines.

Oh yes, quite normal. I always make sure the neighbours aren't around if I am starting mine after she's been left a while.

I believe it's the horizontal arrangement of the cylinders. Anything unburnt just sits there rather than draining away as it would in a "vertical" engine.

My 2000 S also pumps out a fair amount of smoke when I start it. Doesn't last long and runs like a dream so I'm not worried and neither is my friendly Porsche specialist!

Thanks everyone; puts my mind at rest. I can go back to concentrating on what a bunch of arses we currently have in power.

looking from under the car on the o/s of the engine there is an oil breather/seperator,change this as this in most case's stops the smoke from start up,it's acsserble on boxsters but requires engine removal on 996 models,no they should not smoke on start up its a four stroke not a two stroke.
