E85 water ingress/trap and subsequent condensation

 Mostly Holland. Sometimes UK.
I’ve noticed over the few years that I have owned the zed that it does have a bit of a ‘water retention’ problem.
i.e. if you don’t stay on top of it then drain channels become blocked leading to all manner of problems.
Fortunately, my roof motor was as dry as a bone when Durham Dave relocated it for me but I have subsequently had to unblock those roof drains on occasion.

I also had to replace the passenger side door membrane and repair the driver side membrane as they were the cause of my sopping wet carpets if I’d been driving in the rain.

The last one has got me a bit stumped however; I’m getting a shedload of condensation in the cabin after a drive in the damp/wet. The carpets are dry (fortunately) and after a poke around in the enginebay I discovered that the padding just forward of the firewall is absolutely sodden at the bottom on the passenger side.
The scuttle drain seems ok, no blockages, as I can inch a flexible draincleaner wire almost up to the scuttle from the opening inside the enginebay. So I’m left to conclude that it might be because I don’t have an undertray and that water is coming in through the bottom of the engine bay perhaps,

Or is this a false conclusion?
Are there any other theories on how that black padding can be so wet?
 
Hi Chris. Just checked my firewall/bulkhead padding and it's bone dry. You do know there are 2 scuttle drains in the engine bay ?
This one on the drivers side20200126_152424.jpgand this one on the passenger side20200126_152537.jpgI don't know which one you've checked but maybe the other is blocked ?
It's a worthwhile job removing the scuttle panel to have a good clean up underneath...you'll be amazed at all the detritus that has gathered there ! :thumbsup:
 
Thx patriot.
Yeah i checked both. Both are clear.
I’m going with the idea that it’s spray coming in from underneath due to the undertray being absent and there’s more of a clear path through for the spray on the pax side.
Been meaning to get an undertray sorted for a while now as there’s a positively rambunctious draft that permeates through the transmission tunnel and up my left sleeve!
:lol:
 
Gah!
Discovered a swimming pool yet again on passenger side floor only today.
Car’s been sitting for a week or so. Firewall padding has dried out a bit in the meantime.
Will need to check door membrane hasn’t lost integrity after replacing it back in summer.

Failing that it will be a scuttle off job to make sure that isnt the culprit.
:headbang:
 
See the usual suspects have been covered, have another that caused an issue on mums mini that’s worth looking at.

The window presses itself against a rubber body seal & doesn’t have a separate door frame.

On mum’s 10 year old mini, it has hardened & there was a point where it was sneaking in, maybe that’s also worth checking on your Z

Good suggestion thx.
Its got the hardtop on atm and i know for a fact that the seal around the window isnt as good as with the soft top.
The stormforce cover i bought from forum member @agrimes1989 should prevent it getting any soggier over the wet weekend ahead....

Note the wet patch by the drivers door where i was wringing out my shammy leather after soaking up the pool under the seat. I'll never get those 20 minutes back. :x

At least I don't have to worry about wood laminate warping in the damp cockpit Fred. :lol: :poke: :fuelfire:

Damp...what's that then ? :P :rofl:
 
Going to dive in under the scuttle when it stops raining as I suspect that may well be the source of the water ingress.

Current scuttle is obviously the original one and now looking a bit faded and will probably be quite brittle by now. Is it worth replacing it with a new oem one?

Probably a good idea to clean and lube the wiper contacts. I couldn’t find back the how-to page on that although I’m sure I saw it here. Anyone got a link?

Could also be from punctures in the roof from the claws of this little bleeder :lol:

hi Reference Pussy cat leave a bottle of water or orange peel on the roof cats don’t like things they don’t understand.
