Hi all,

I thought i'd got a reasonably leak-proof car, but recently leaving it in the rain for just a few hours will cause a puddle in the driver's side footwell!
I've checked all the tube/wire grommets and clutch cylinder cover on the wing under the bonnet - everything sealed up nicely with silicone. The door seal is in good shape, and it doesn't look to be coming from the roof anywhere. I'm wondering if the seals round the lower part of the windscreen are letting it in. Any ideas?

Have you checked the rivets holding the VIN plate on? Also washer jets are another potential leak point

If your confident all the sikkaflex/silicone is as good as you say(recently sealed over a pin hole which caused a leek in my griff),then it could be coming in through the windscreen seal.I had this on my Chim,and to find it i got my wife to pour a kettle of water over it whilst i got into the footwell to look for it.Once the carpets were pulled back the water could be seen running down the bulkhead behind the pedals.

Likewise - re-siliconed the clutch master cylinder cover - put clear silicone over the pedal box bolts - clear silicone over the hose and cable grommets. Stil got damp drivers side carpet!!

Just before LeMans, I had to replace the clutch master cylinder. Noticed that the foam 'gasket' did not extend all round the grp cover. So when I was 'boxing-up', I applied silicone to the joint faces of the cover and inner wing. At the same time I also dug out the old sealant around the brake resevoir and re-applied silicone here and around the wire for the low brake fluid switch.

Job done - dry as a bone now in the drivers footwell.

Hi
I had the same problem about 4 months ago.

I used a hose to get water to flow down the windscreen and masked of areas under the bonnet.

I actually found most of the rivets just dripped ocassionally but the brake cylinder was like Niagra Falls.

I replaced all of the rivets and sealed them. I cleared all of the silicon from around the brake cylinder and re-sealed it with black silicon that I got from Halfords.

Retested and the damned brake cylinder still leaked. I cleared it all out again and used sikaflex. It still leaked. I put some polythene over it and taped it down with duck tape and it was fine.

I then remembered I had some Capt. Tolley's creeping crack cure. I applied this 3 times around the brake cylinder - retested it and it has been dry since. I wish I had used Capt. Tolley's first as it would have saved me a lot of time and money.

Hope this helps
Pete

It could be getting in through the hood, where it joins the body and the velcro is. Apparently it tends to flow to the lowest point, hence ending up around the driver's footwell. I restitched the hood around the velcro area (obviously only relevant if the stitching is coming away) and painted on about half a can of Fabsil, since when it hasn't leaked. I bought some Sikaflex but I can't work out how you get to the clutch master cylinder etc, if someone can point me in the right direction I'd be grateful.

Clutch master cylinder is in the off side wing.
It should be covered by a black plastic disc and sealed around the edges. It is next to the Brake fuid container and is often neglected.
