Water getting into your Buick LeSabre's smog pump is not normal. In fact we
can't imagine how water would get to the smog pump. The only thing that
could be the culprit is either water condensation in the smog air pump or a
heat gasket leak which is so severe that water from the coolant passages in
the engine block is making it's way to the air pump from the plumbing
between the air injection pump and exhaust manifold ports. Keep in mind
however that if a head gasket problem is this cause of water getting into
the air injection pump or smog pump, your Buick should be running very
poorly.
