My reasoning as to what's happening is that there is so much spray around it gets in through the heater air intake, and instead of draining out of the bottom like it should, ends up on the heater matrix and then trickles through, dripping onto the gearbox cover and thence onto my left shin as it rests against the transmission tunnel. This is probably exacerbated by the fact that unlike a proper setup, I have a Heart of England stainless steel heater box, which although it looks a lot nicer than its rusty old predecessor, is something of a triumph of form over function.

Any road up, a couple of Rivnuts in the existing inlet holes, a couple of short spacers, and a bit of scrap 1mm ally sheet, and we have a prototype rain cover that should still let air into the heater.

Of course, the real reason for doing this is to guarantee good weather. It's bound not to rain now so I won't get a chance to test it out properly smile

Neat job, hope it cures the issue, if not perhaps a little more overhang with a turned under edge to make rain droplets drip off well away from the inlet holes ?
