my pcv valve looks like it may be sucking oil and water from the back of the valve cover, does this mean i have a head gasket problem or an intake gasket problem?

It will depend on what type of driving you do.If there is alot of quick/short trips,some condensation will form.(which is normal)If this is not the case you could have an internal coolant leak(such as head gasket,intake gasket etc).
If it were mine,I would either clean,or replace the pcv valve,and keep a close eye on the coolant level.
Also...if you have recently had any "overheat" condition...it could point to potential gasket problems....

 

i have had no over heating, coolant stays at level, just replaced pcv. must just be condensation.
