Check around the sunroof area to mate...
The battery tray and fuse box area is bad on all mk4 escort front ends due to the small rubber stopper on the lip on each wing, where the bonnet rests...this stops the water running down the lip...instead it falls of and rest in batt tray and under fuse box!!
Cut a small bit out each like a wee tunnel so water can travel down rain gutter!!!
Prob solved lol
