Had a chance last night to look at the scuttle. CTook it off and looked underneath. There were a few bits of tree/leaf in there but not too much really. Not enough to block up and cause water to come in through fan vent.
Still is letting water in but only when it rains really hard.
when putting hand under back of dash on passenger side, feels slightly wet on the cardboard bits.
Also i am losing coolant, although not sure if this is directly relating to this leak, as leak only happens when there ha sbeen heavy rain.
