    Everybody, it seems, asks the same question. NO, there is not supposed to be an o-ring around the top bearing. That groove is a collector groove leading down to the intake manifold.

    The spaghetti seal is the same stuff used in the lower units. Buy it cheap at mcmaster.com They call it 3/32″ buna-N cord stock, 70 durometer.
