Default 1.8 zetec head vacuum

hey guys,

car has developed a vacuum in the head quite a strong one aswell... can feel the unscrewed oil cap being pulled in when running...

is this normal or a sign that the valves/seals are fubar or close to...

i have half the head apart at the min as i wanted to double check the timing which is good
