I have a 2003 Boxster S that smokes on startup occasionally.
Sometimes it is considerable blue smoke. Any of you guys heard of
this. The dealer says it is normal. I have 23,000 miles on it. I
don't drive it that hard. Was also wondering what someone should
expect for life of one of these motors?

Thanks. Any input would be most appreciated..

I have a 2003 S and there is no smoke on startup. If I recall correctly,
white smoke
is from water, Black is from unburned fuel and blue is from oil. This being
said, do you
use any oil? If so, how much? Give me the exact details of when you start
it up (how
long it has sat, outside temp, etc.) and I will try to duplicate it with my
wife starting the
car to see if I can see anything at all.

As a side note, how do you like it?

It usually happens when the car has been sitting a while maybe a week.
But it occasionally does it after it has just been run. You guys may
have something there on just when running a short bit of time. I was
at the resteraunt the other night and I had to start it again toi move
it into a different spot. After eating it smoked quite a lot but
always quits. This smoke is definately from oil.

Dan I love this car. It handles like a dream, it has great styling
and I feel quite comfortable in it. I would love to have a few more
inches in the leg room department though. I have had zero problems
and porsche has been a dream to work with on service.

Thanks for your response

My 2000 will smoke if it sits for a week or so, also. Dealer confirmed
that this is OK.

My BMW motorcycle is a horizontal and smokes after a week or so of sitting
..... just like my 01 Boxster.

I sold Porsches for a couple of years. About once a week we would crank all
the cars in the line and let them run for a bit to maintain the batteries.
You could tell the cars that hadn't been driven for the week prior by the
smoke coming from the exhaust. These were brand new, never titled cars.
So, I can tell you that if your car sits for a week or so at a stretch, this
is very normal.

Smoke on startup of any flat horizontally opposed engine after some time at
rest is a given.

Oil will at rest gather in the valve covers and no matter how good a valve
guide is, it must have some clearance to be able to move the valve to an
open or closed position. Oil resting in a valve cover will eventually seep
through the seals and the guides into the cylinders. Also it takes very
little oil on startup to make a great deal of smoke.

On a radial engine where some of the cylinders are located upside down, you
should always manually pull them through a couple of revolutions simply to
avoid hydraulic lock and catastrophic damage. It is simply the nature of the
design. Every radial engine you have ever watched fire up in the old war
films smoked on startup.

So never fear, at least with a flat design, you at least you don't have to
hand crank it to avoid damage, unless your Porsche has really been sitting a
long time, then I may actually recommend it.

To the original poster:

While some smoking on startup is a characteristic of the flat-6 Porsche engine,
for various reasons, any smoking accompanied by cold/warm/hot starting or
driveability problems is cause for serious concern.

Could be something relatively simple to fix like a leaking fuel injector but
could also be something much more serious. (My '02 started smoking on startup
and the cause was a failed air/oil separator which almost cost me the engine.
The separator failed in such a way that excessive vacuum pulled quite a bit of
oil from the engine into the intake and this oil was pumped through the engine.
If I had continued to drive the car, this oil could have caused a hydraulic lock
up of the engine and at anything over idle this could have destroyed the
engine.)

If the smoking continues after startup, appears on deacceleration, under hard
acceleration, if accompanied by a howling noise, excessive vacuum at the engine
oil dipstick tube or oil filler tube (with the engine running at idle), shut off
engine and get car to nearest qualified service department with strict
instructions not to start engine, drive car, until source of symptoms found and
corrected.

Sincerely,

MarcW.

Same thing happens with my 2000 'S' especially if the car is not used for any great length of time. I think it's normal.

If all of these cars are using synthetic oil it seems strange the
smoke has a blue or blue-gray tint.

My experience is that syn oil doesn't have this color.
