Interior Wetness ....what to check

[percymon]

Update...

the good news - rear footwell continues to be dryzabone since i did the floor repairs 

the bad news - front end still leaking like a seive - two hours in the rain / thunderstorm last night resulted in half an inch of water in the drivers footwell (fortunately i'd lifted the carpet out of the way in excpectation, and still no underlay back int he car so water only on the metal floor).

I haven't taken the front wing off, but i have removed the wheelarch liner for a look - there appears to be nothing amiss - plenty of factory wax/waxoyl in place and even the point where the sctuttle drains through to the wheelarch looks sound.


Next step is to block off the scuttle drain (to wheelarch area), fill with water and look for air bubbles !!


Getting a bit miffed about the potential puddle evry mornign, but its not going to beat me

mines suffering from this at the moment, more from the rear than the front... im going to pull mine up and get a hose in there to see if i can see where its coming in. Its on the passenger side so none on my side

A whole year and a half of wonderful car, and a week before her MOT, the skies open - so much it would make Boscastle look like a stream! And guess what?

The driver rear footwell about half inch deep and the driver front also soaking. The seat looked wet but in fact was bone dry. Now you see the problem is mines a 3 door and sunroof. No obvious wet patches anywhere else in the car other than one drop on the door seal, centre of the car.

Sunroof and seal and drainage holes all checked and clear.
Haven't been underneath yet as it hasn't stopped raining yet!

Only mopped up the water as best I can but after two days its starting to smell of cabbage already.

Any thoughts would be most appreciated?

Todays installment !!

rained heavily for a short time last night - usual small pool of water in the footwell


blocked off the scuttle drain (to wing/wheelarch) - filled with 3 inches of water, not a drop in the cabin, no air bubbles to be seen.  opened up the drain again, let all water rush out, then tried hosepipe in scuttle and drain are - not a drop.

Hosepipe up the side of windscreen again (been here before  ) and managed 2 drops in the footwell - not much for probably 100 gallons of water on the outside 

So took windscreen A pillar trim off, and sealed the side of the windscreen with silicon, refitted - awaiting the rain overnight  :embarassed: :embarassed:

Break out the champagne guys n gals  - i've found the blasted leak


You will not believe it - in fact i really need to post a pic of the failure zone for you all to appreciate it.

OK, the root cause of the ingress was the factory sealant between the bonnet hinge plate on top of the inner wing/front member and the wiper spindle.  There was a tiny black speck of dust on it, or so i thought - turned out it was a hole in the sealant - at most 2mm across. I could cover it up with the smallest application of a touch up stick 

Absolutely unbelievable - trickle water on the sealant point, water constantly running into footwell, trickle water an inch further forward and dry as a bone.  Dabbed a bit of clay cleaning bar over the site, sent gallons of water over it with hosepipe and not a drop in the footwell.


So i poked about with a micro screwdriver and at best the hole is now 2mm diameter ! - will apply soem underseal with a cotton bud tomorrow night, and then a few weeks later a dab of touch up paint over the top.

Off for a few well overdue    now
