Umm what exactly does the pcv valve on a 92 ssei look like? i went to look to find it and all i see is a flat piece of metal that has 2 bolts in it that says pcv valve, is it under that flat plate or does my car just not have one? if it doesnt does that affect performance?

It is indeed under that plate. There is a spring, PCV, and an o-ring. You'll have to pull out the spring, and the PCV should come with it along with the o-ring.

Ok, thanks, gonna order the valve from gmpartsdirect, now also i wanna get a boost control solenoid, any posts anywhere on her about how to change it? hard?

Just go to the auto parts place to get the PCV. Not worth the wait to get it shipped, it'* too cheap to begin with.

The BCS just has wiring plugged into it, two vac lines, and is held in place with a bolt or two. Not a difficult job.

It'* a very easy job and is only held in by 1 bolt. I've had to replace mine. The PCV and BCS are probably the easiest parts to swap out!
