Water getting into my W123

Anyone out there from the Cleveland OH area that is willing to show a friend of mine where the common leak spots are in his W123? Getting real tired of water! Will pay a small fee for discovering the source(s). He had some area around a grommet repaired I believe near the firewall.

I can't come round to show you but look in these places

1) Windscreen rubber - I was amazed to see the amount of dirt in my old rubber when I removed it - water must have been percolating through the crud and past the seal for my leak...

2) Bonnet / hood hinge pocket areas - http://www.peachparts.com/shopforum/body-repair-restoration/286079-w123-hood-bonnet-spring-pocket-refurbishment.html

Look at the end of this thread too to see the result of leaks at the front - outer sides of footwell rusting...

3) Sunroof drains - rubber hoses run down inside front pillars - if these are leaking you'll likely see water staining on the headliner

4) Bulkead / firewall between engine bay and cabin has a trough that holds windscreen wiper motor and air intake for heater. The drains for this area are funny shaped rubber things that are just behind the front anti-rollbar

5) Bulkhead area under the battery tray. Remove battery and tray to investigate this bit.

These are the most common areas. However, don't discount rust and holes...

Don't overlook the small drain-hole that is directly under the hood hinge pin in the pocket. You need to poke there with a piece of wire to find it!

There is also plastic funnel glued under the wiper that catches and funnels water from the slit under the wiper to the trough. It fell off on mine!

Those drains are a pain - I've tried to describe their positions in this picture

Is tehre a way for water to flow from the sunroof to the rear window channel? I get water coming from under the window in the trunk and the window is sealed well.

there is a rubber tube attached to the rear sunroof drain that is routed in the c pillar and if it's torn, or the rear drain is rusted out, it'll leak in that area.
