Could you elaborate more on this... I am having the same issue (Exactly) and even though I have not put my eyes on it myself, my mechanic tore it down a second time because that I what I told him. Problem is, he put it back together before i got to look at it so whoknows. Is there any way you could tell me exactly which hole or holes is the passageway up to he head. If not, my only option is to tear it down myslef so that I can put my eyes on it as its done.
