Actually kids... the PCV (Positive CRANKCASE ventilation) is on the underside of the manifold.... connects to a hose on the crankcase. 
The rocker cover does have a vent, but it doesn't have a PCV valve. Either way... that's not causing the car to run so poorly.

Would you at least just test the PCV Valve, Fubie?

A few questions...
What is the secondary filter by the throttle body? The PCV is marked, your EGR doesn't look blocked although I can't tell where your vacuum line for it is going and how did you setup your FPR on the passengers side?
Also, if you pull your oil cap while the engine is running it should die or damn near die unless you have a serious vacuum leak.

The PCV valve is fine. works like to should. I was able to get it up to 3K today. but it took about 8 secounds at WOT to creep up there. And I tryed the oil cap thing. it did not even flentch. got a lil oil on the valve cover, but it did not effect it in anyway.

removing the oil cap doesnt always affect the way the car runs. On some it'll stall the engine. On others it does absolutely nothing.
now this is an '81 correct? Make sure the dropping resistors for the injectors is fully plugged in and that it's sending current out to all injectors.
what have you checked so far? Have you verified that the AFM connector is plugged in and not wet or corroded? Have you messed with the AFM at all prior to the problem? Have you verified that the Ignition Control Module is functioning? And finally, what did you chang or do to the car between the last time it ran alright and when it started having this problem?

ok. I changed Nothing at all. Droping resistor's, umm. where are they? i pulled the AFM to clean it. but it was spotless. What i have checked so far: Spark Plugs, PCV, Vaccume lines, Rotor buttin, and cap. It has new spark plugs and wires. New Ignition Control unit(150$ spent), rebuilt Dissy.

its out of time thats what it soundsl iek to me... i had placed my 83 turbo to TDC then placed the spark timing to number 6 timing... the car started, but i would have to keep it at WOT to keep the car running... even thern i still found some gasolne inside the motor oil.. so i decided to stop and rest

when you cleaned the AFM did you open it? If you did then check to make sure none of the internal wire leads are making contact with the AFM body. This will ground them out and cause the issues you're having. Even if you opened it a month ago, if you opened it at any point check that. Vibration and time may have slowly led it to ground out. If you never opened the AFM then this most likely isnt an issue and wouldnt warrant opening it up to check.
The dropping resistors come in the form of a metal box looking thing mounted on the drivers side of the engine compartment right around the windshield washer reservoir. It has a large connector with quite a few wires running in/out of it. You want to check this for continuity between the inputs and outputs.
And finally make sure your plug wires are in the correct firing order. You may not have changed them but that doesnt mean someone isnt F'ing with you
