^^ Wondering the same thing. If all of that white smoke did disappear spontaneously, Julian@MRC was in fact correct with his diagnosis.
I hope we get a follow-up on this one.

Did you ever find out what the problem was? My '03 Z has the same problem. No overheating, and white smoke pours out of the exhaust only on startup and revving in neutral. Trying to get an idea of what I need to do to resolve this.

I doubt any of the rest of you likely have this problem, but whatever moron had my car before I bought it didn't ever change the oil by the looks of things. That said, the PCV system had to be flushed to get mine to stop smoking. I replaced the PCV valve and that wasn't even enough... the flush stopped the problem though!

My coolant and oil never mixed, but a Nissan tech told me that the valve stem covers have been known to need replacing on the 3.5 V6 engines, which could cause that to happen.

i just had this same thing happen the other day (white smoke for a second on start up). the Z sat for about a month. Last time I drove it, i washed it, and parked it...maybe drove it 3min each direction...then drove it that night for about 3 min in the rain. Start it up a couple of days ago (about a month after the above mentioned short/wet drives) and get white smoke for about 2 seconds that had a heavy fuel smell, then all was good. ran rough for about a second, then fine. any ideas?
