Latest update.. I think my windscreen was replaced at some point in time by a previous owner and the rubber seals that go along the A pillar not refitted correctly: the rubber was laying flat on top of the glass and could be easily lifted to reveal the edge of the glass, rather than with the flange folded back and pushed in to meet the edge of the glass. This creates a 'gulley' for water to run down and a slightly raised lip, rather than a flange of rubber laying flat. I hope this will help the problem in the rear (perhaps water was running quickly all around the inner edge of the A panel, round the bottom of the drivers door and then out by the centre pillar, entering the rear footwell here??). I say I hope - because no matter how many buckets of water I poured over the back (and front) of the car last night, I could not seem to pick up where water was getting into the back. This part of the problem is ongoing.
However, I positively confirmed water entering the drivers' footwell, so I went ahead with trying to find and seal the bulkhead/bonnet release leak. I thought it'd be best to try and seal from the outside if possible, just to prevent any water sitting above the panels if possible..
Wiper arms were a pain to remove (when would they ever be easy), but a lot better after applying heat gun for a bit. Made sure to use sellotape to mark the positions of the blades before removal. Scuttle panel then pops off with some coaxing, and can be fully removed once washer hose is disconnected. Interestingly, someone had already tried to fix a leak on my car - a thick white bead of sealant runs for about 15 inches on the drivers side just below the windscreen, which the scuttle sits on top of. I doubt that this was ever a location for a leak, though.. unless the windscreen was refitted poorly.
The hole pointed out on page 1 of this thread was by no means as large on my car - in fact I could not even be positive that it was a hole.. The bonnet cable grommet appears to be in a different place for me. In any case, I applied sealant all along the back of this edge - but not all the way toward the engine so as to still allow a channel for water to drain. It is worth noting that the water deflector clipped in just above will channel water directly down on top of the grommet release and the edge I have sealed. Due to this I thought it wise to apply more sealant to the grommet - however even more may later be needed if the leak is here rather than at the seam. Pictures below, in order..
