I'm not positive on Nissan's, but I know on Honda's there should be two notches in the cam gears.
The number 1 piston should be top dead center, and the two cam gear notches should be facing each other as close as possible.
My boss goes to that almost every year. Me and Kris might go but there's a good chance neither of us are going to be running our cars... Seeing as how neither of ours are in running order as of right now.
Damn dude, that sucks. I hope you get it all worked out. Dan's good with stuff like that, talk to him and I'm sure you two can figure out a way to get it back in working order.
