Thats the proper location... But the cap should twist off, there are no screws on the 93 PCV cover... But it will have the spring... There will be an O-Ring on the PCV cap, do nit loose it...

It is located on top of the motor, at the end by the belts. (passenger side) Look for a cap that will twist off.

OK, so here'* an actual picture of your engine bay (actually a '94, but who'* counting?).

The PCV valve is located upwards and to the left of the large black plastic bumpy thing (your upper intake manifold or plenum as some call it). You can't really see it too well in the picture, but maybe it will give you an idea when compared to the diagram posted above.
