PCV Valve

Remove PCV valve from valve cover. Run engine at idle, placing thumb over end of hose to check for vacuum. If vacuum does not exist, check for plugged hoses or manifold port. Turn engine off. Remove PCV valve. Shake valve to ensure needle inside valve is free. Replace valve if needle is not free.
