i have a 98 camaro v6 is there any way that i could set up a pcv oil catch can on my camaro

 

Yes there is. Remove hose from present PCV valve, insert onto inlet fitting of catch can,
run new hose from outlet fitting of catch can to PCV valve.
Are you getting blow-by issues (oil in the vent hoses), or just want to do this for fun?

 

it dosent have pcv hose the pcv valve is on top the intake manifold inside of it. and oil is coming through the thottle body.

 

Doesn't your engine have another vent hose run from the throttle body to valve cover?

 

no all it has is a vacuum hose from the throttle body to the evap solenoid valve

 

Looking at the 3.8 valve covers, I'm now seeing your problem. You can either:
1) drill a hole in either valve cover (after removing it of course) to accept a breather grommet, and install an elbow. Then run a hose from there to a catch can, then out to a full manifold vacuum source on the engine. Or...
2) instead of drilling a valve cover, pick up another passenger side cover which has the oil fill hole, and modify (drill) the cap to accept a grommet and do as in #1.
If it were my car, my preference would be #2 for neatness and reversibility.
But, in doing either way, you're going to be creating more vacuum in the crankcase. So, you're going to want to have a breather or breather tube in the opposite valve cover than where you install the catch can hose, so that the crankcase can breathe in and out. Your option would be an aftermarket breather, or a vent line connected to the air intake tube.
