the positive cranckase ventilation is going to be on the valve cover. usually has a rubber hose about 5/8 coning off it and running to the intake.

usually they are on the valve cover. buy a new one and look for the old one. check the tubes connected tfrom the engine to the air breather

It's not a PCV valve like back in the day . It's a fix orifice in the valve cover . Where the breather hose hooks to the valve cover . You would need to take the valve cover off an clean the orifice with carb clean or brake clean .
