hello

well if it ever happens again I will, but now im just gonna play the waiting game to see if it happens again because besides that the car has been running perfectly and butter smooth

nomunk,

I understand. Keep me posted if the issue does happen again.

Thank you,

On my 04, and a friends 05 GXP this was a head gasket leak. On mine coolant was leakin into piston chamber 5 and when I started the car it would bellow plumes of white smoke/steam for about 5 to 8 minutes.

I would recommend not waiting for it to happen again and having it investigated, if it is the gasket, it may only be rarely leaking in which case if you catch it now it may not be as expensive as catching it later like I did.

I used a cheap fix, because no dealer or local guys wanted anything to do with my Northstar Pontiac engine. I guess changing the head gskets is a two to three day job, and according to all of them the car will never run the same, and almost not fit back in the hole it came out of....

Just my experience with the white smoke....
