Ron, as far as I know, there's only three fasteners. Two are studs and one
is a front cover bolt. You may have electrolysis between the aluminum water

Sounds like the oil line is an attempt to get oil up to the head (and the
upper tensioner) quicker than normal, in order to prevent the Death Rattle.
