air box is famous for rotting out, I believe alot of people have just by-passed them, but that will depend on the emissions standard in your area. try looking in the local j/ys for a replacement, but they're probably rotted too.

as far as what fits. 86.5-97 HBs and 86.5-95 pathys are interchangeable, aside from the changes nissan made. i.e. carb to throttlebody to injected, z24 to ka24, vg30 is the same except for intake system. dashes changed around 94 I think. hope this helps.

could be the oil pump, have it run and open the oil cap, if its spitting up at you its fine, if not much oil spits at you its bad
