Sealing between cockpit and engine bay?

[eSteve]

Hi all,

I've spent some time over the weekend dry fitting my steering and pedal box. This has got me thinking about the engine bay and the cockpit bulkhead:

It it necessary for the bulkhead, that is the panels at the ends of the footwells (and I supose the transmission tunnel walls) and the panel on the front of the scuttle and below/infornt of it to be sealed?

Obviously from a fume, pong and druaght ingress in to the cockpit point of view it is a good idea to have it all reasonably air tight but will the IVA inspector being looking/examining the sealing of the cockpit from the engine bay?

I've just had a search of the IVA manual for a few terms that might indicate some requirement but found nothing.

Does any one know for sure, is it / or isn't it inspected?

Perhaps some members with IVA experience might like to comment.

Thanks,

Steve
