Had a go at stopping the rainwater dripping onto the Air filter an Injectors
if you get a mirror and look under the water trough you can see where the water has been leaking through and tracking down into the engine bay.
Wipers and plastic trim / cover removed you can see clearly at each side how the water gets on the air filter / o/s innerwing and the n/s inner wing, from the bottom of the screen glass in has a clear run down missing the water trough and somehow needs to be rerouted, the rubber bonnet seal is clearly not long enough for as well, also the plastic air intake fitted in the metal rain gutter / trough was distorted out of shape along its bottom edge allowing water through to the engine bay, This wiper spindle was the main culprit of the water around No 4 Injector

once you remove Ford's bodge to the problem (plastic film glued on) you can see why,

with the water trough removed i took the air vent off and refitted it using silicon sealer and fittin extra rivets along its bottom length (now sealed), then I set about creating rain channels / diversion with Butyl sealant tape, I've tried diverting the water from the screen ends to go into the trough and down the inner wing gutters (where it should go) I have left the white tape on the sealant where it would stick to the plastic trim that sits on top, so its easily removed again.

Next was the drivers spindle, i filled the hole around the spindle from underneath with the Butyl sealant, then on top I filled the space with silicon sealant and then stuck the original ford foam seal back on top,

I did the same with the middle spindle but no foam seal and also ran a length of Butyl sealer along the top where the Trough panel sits
