White Smoke Puff And Coolant Level

[Noor]

So I a have 00, C4 Cab. It has 12K miles on the new Engine. (total of 32K miles). Yesterday I filled the gas and checked the Oil and Coolant levels. Oil was at 5/8 before the full mark on the dip stick and Coolant was at "Min" I got the oil changed about 5K miles ago.

During the day (80deg sunny) when I started the car I thought I noticed a white Smoke Puff.

Took the car to work. Allowed it to cool down and checked the coolant again. It was still on the 'min' mark.

Then later in the afternoon, drove home, once I got home I checked he Coolant level while Engine was running (No I didn't open the cap) just checked it thru the Expansion tank, the Level was at 'Max' while the engine was Idling.

My concern is abviously the white smoke puff and it being somehow related to the Coolant.....Coolant in the engine is a bad thing......!

So question is, is this all normal? I have read several posts on White Smoke Puff but nothing definite.

Does the Coolant level vary during vehicle operation?

Any help would be helpful..

As I understand, under no circumstances the car should loose any coolant...It indicates either an external or an internal leak.

The car is under full Porsche warranty.....So I can always have the dealer check it.!

I did have'em do a pressure test on the cap and Exp. tank and it all passed with flying colors. This was few months ago.

Thanks

Noor.

Don't worry, they all do it every once and a while. Boxer engines can sometimes get a little oil pooled in a cylinder that causes the smoke on startup. My 02 996 does it every once and a while, but only from the right bank. I figure that the ring gaps on a piston must get lined up to let the oil past.

It is not coolant, it is oil.
