Is anyone familiar with the Transit construction sufficiently to offer any
helpful suggestion about tracing a worrying water leak?

The model is the Mk3 and it has a fibreglass "high-top" which has been well
fitted and doesn't show any signs of leaking anywhere.

The water is running down right in the extreme corner of the bulkhead
(INSIDE THE CAB) where it joins the inner wall (double-skin) of the area
under the near-side door pillar (immediately above the front n/s wheel).
This is just forward of the door lower hinge bolts. The water finishes up in
a tight little corner where the bulkhead, bottom of the door pillar, and
wheel bay, join. Just behind the shock absorber upper mounting.

There is nothing to indicate that the windscreen is leaking. The door
pillar appears to be constructed of two vertical channels. One can be
checked by removing the trim, between it and the windscreen, inside the cab.
The other is more of a problem but, if it were running down that, it would
presumably be visible through the hole that one uses to get to the door
lower hinge bolts. There is no evidence of water in there.

Neither is there any indication of water leaking through the bulkhead in
this corner
of the windscreen.

If anyone can help in any way I shall be very grateful because, although
this is only a small leak, the water runs down into the thick sponge-rubber
floor matting Ford have fitted to the cab floor, in order to deaden diesel
sound, and the result can be easily imagined.

Have you checked all the grommets mounted in the bulkhead on the engine 
side?

From what I remember, we used to get the occasional new one at work with 
badly fitted windscreens (both by the factory, and if they'd had the 
windscreen replaced), which could be problematic to locate the actaul source 
off the leak.
Usual way to check for leaks is to leave a hose running down the motor at 
various points, until you found the area the water was getting it.

not the fresh air intake drain holes bunged up by any chance is it?
Derek

Can't find any fresh air intake drain holes. Can you please give me a clue
as to where I should be looking, Derek?

Have also checked all grommets, but no problems there.

I have found a nasty rust patch where two panels are welded together and
just above where the water is congregating. Have treated it and sealed it
well with body filler and if tomorrow's promised rain arrives I should know
if that has done the trick.

I knew I should have kept stumm we changed over to mercs ages ago I'll have
to check with one of my pals where about the holes are you say mk3 tranny
(bear in mind I have been in haulage since the end of 3wheel artic days )
what year do you mean I would be thinking of this type

least) 3 different models prior

Sorry I haven't answered your message before.

Yes, that's the model shown in the picture, year 1998. A bit old now but it
is a motorhome and they tend to be better looked after than your average
van, of course. (Certainly a bit better than the one in the pic!)

I've traced the water leak back to the lower nearside corner below the
screen and on the CAB side (inside) of  the bulkhead. How you search from
there, I don't know. It could be coming down the inside of the door pillar
(which itself is split into two sections), but you can't get to them without
half dismantling the van!

If I can't find where it comes in, what do you reckon to drilling a small
hole (5mm) in the corner of the bulkhead so that it can drain out into the
engine bay? It really only amounts to a very small quantity of water that is
getting in but once it gets into the sponge-rubber floor insulation it
builds up, and has no way of drying out?
