For the benefit of many of you wondering how to stop a typical leak
through worn out and deteriorated wiper pivot seals, I am providing
the following sequence of photos. The first photo is to show you
how important it is to keep the cowl clear of debris. This pile of
leaves and twigs were dug out of the cowl by reaching up through
the fresh air opening on the passenger side of the dash.

I know most of you wont have the luxury of having your A/C or
heater box removed to reach up into the cowl to clear the debris, but
you should know that there are drain holes in the sides of the cowl
where you can dig out the bulk of the mess. Its not fun and is very
time consuming, but it may possibly prevent debris clogging up the
drains and causing water to back up and overflow into the fresh air
inlet. Or worse, the built up debris provides a place for moisture
to remain, causing rust to develop around the inlet and on the floor
of the cowl.

The following sequence of photos shows how to install the grease
fittings, seals, gaskets, and caulk strips that are provided in a kit
sold by Schumacher Creative Services (www.engine-swaps.com).

1. Drill 3/16 hole through pivot base.

2. Hole drilled only through outer wall of pivot base.

By the way, dont forget to shoot a little grease into the pivot base
using the new fitting. You can skip the step of installing the grease
fitting, but Schumacher says it can prevent water from seeping down
a loose pivot shaft (and it might do away with a squeaky noise coming
from a dry one.)

The kit comes with very concise instructions, but I
thought I would give you a preview of what you will be getting into.
You should probably plan on taking the better part of an afternoon to
replace the seals from start to finish, including replacing the linkage
arm nylon bushings. But that is a story for another time.

Don't be afraid, it's not that bad,
