Hi all, I have read the couple threads here and have a haynes manual as well. But I still have 2 questions on a civic 1.6 d series head gasket change. One being is the removal of the distributer neccesary and the second is the previous owner put a new timing belt on so I was not plannning on changing it, so I have heard from others that it is important to keep tension on the belt so it does not slip off the crank. How would one do so?
