Rain water is leaking into the cabin behind the pedals via the bulkhead on my 997 (RHD).

The drain holes around the battery are clear. Water pools just behind the drain point (rear left of the battery, by the bulkhead), where there is a seperate bulkhead panel that appears to be bonded in place to the main bulkhead structure.

Despite loads of seam sealer between where that panel joins the bulkhead, water must be creeping underneath. Please see my video below (interior side point of view) where I turn on and direct a garden hose to the area around the drain point (rear left of the battery, by the bulkhead).

I have tried resealing where the panel joins, but it's a very awkward area to work with including crevices.

I am looking to understand all solutions from others who have had this problem (whether 997, Cayman, Boxster), before I remove the master cylinder and brake push rod to get better access to the area.

Thanks in advance.

 

Very little 997 discussions on 6speed. I suggest asking on the Rennlist 997 board.
