Well, add me to the list of Xterras with bad head gaskets. It's been leaking just a little bit for quite awhile (white smoke for a few minutes at startup after it's been sitting for a while).

I ordered all the stuff today and will be working my way through it over the next several weeks.

Luckily I have several vehicles these days so I can afford to take my time and have the X down for as long as it takes.

I'm not sure how helpful pictures will be since others have already posted pretty good ones (here's one), but I probably will anyway.
