Rain getting in via air intake - problem?

[Devon Pete]

Hi, I just changed the flat battery on my van. It is a 1.9 tdi with one air filter on the left. The battery is on the right, next to which there is a void (I asume only the air cooled vans needed both air intakes). When I took the battery out I noticed that there was quite a bit of rain water standing near the battery tray underneath the air intake on the side of the van. It's not rocket science to realise this must be caused by rain dripping down via the air intake and standing on the battery tray. I assume therefore that it must happen to all T25s. It made me a bit nervous about rust starting on the basis it will be outside most of this winter and not driven regularly (car port still under construction!). Is this a common problem when vans are left standing for a while or am i worrying over nothing? If it is a potential problem, I was thinking about drying it off and spraying in some waxoyl, not sure if that's a good idea of not?

Any views welcome.

Cheers

you wont really stop it coming in there but i agree its not ideal most of the vans i do have these areas rotted out, ,it would do no harm to pop a hole in the centre depression to let it escape, well it will help anyway but note that if you drill up from under then you will leave choddies sticking up that will restrict the water flow out, ,hammer it flat or cut hole with a Qmax cutter, oh and waxoyl or equivalent will do no harm

Most of it gets in when parked though. See CJH's solution:

Nice simple idea that.

VW solution on South African Big Window vans. Whether it was deliberate is another matter.

The other method (seems widely used) is to watch where the rain runs then put a cable tie around one of the 'slats'. Cut shorter, it will divert rain away quite well and stop that annoying 'drip, drip' that can keep you awake at night. Mind you, I really love the sound of rain on the tin top when I'm warm as toast in the duvet...
