Water in footwell
Discussion
Well I have a leaking drivers side footwell on my M400 to and I can't find the answer on any forum anywhere.....
There is mention in Wiki about drain holes in the floor possibly being blocked by stones and grit, but that is most definitely not the problem with my car as the floor has been reset and resealed. I do suspect that water is sitting above the floor under the front clam and running under the structure just in front of the pedal box however, so have meantime removed my mat and carpeting and will be conducting my own water tests this weekend!

I have the running through from the back clam problem to behind the back drivers seat which I need to fix but I can actually see the water running down the front bulkhead from the join either side of the pedal box joint. I've tried injecting sealent which has not worked but can't see a simple fix or a thread on the internet either.There is mention in Wiki about drain holes in the floor possibly being blocked by stones and grit, but that is most definitely not the problem with my car as the floor has been reset and resealed.

I had a GTO3 for 7 years and had most issues. But the water in the footwell was well covered on these forums. I am sure a hunt through the search will find something.
However, the floor will start to leak eventually.
You will have to get the car on a ramp, then drill all the rivets out from the under floor to remove the ally plates.
It is in several sections. The front is the easiest, so do that first. The middle is a pain as the carpets are glued in place, so this will all have to be cleaned up and then the carpets re-glued when done.
It is more likely to be the front or sides causing your problem. So do them before attemping the middle, as it might not need doing at all.
Once off, clean up the box section rails and remove the mounds of dirt and stones that accumilate.
Hammerite the rails. Add a generous layer of sealant to the underside of each rail to help secure and seal the floor when replaced. If while drilling the back of the rivets stay in the box section, then squirt some waxoil into the rails to prevent whats left of the rivets rattling around.
Now use stainless self tapers to reseat the floor.
It is all about access. If you can get the car on a ramp, then the job is time consuming, but easy. I did my front laying under the car on a set of ramps. Bit awkward, but doable in a morning.
Hope that helps.

Hi Gordon,
When you took me a run in your car I did get a drip on my leg I think through the bent not sure if it is related. Tux sells drip trays that cover the area above the wipers motor etc to divert rain from dripping down the bulkhead I would imagine, made in carbon. I had a few grommets I sealed also on mine when I got it. My leak is aircon related have you checked this possibility?

The paasenger side floor was loose when I gave you a spin which I've now fixed and is dry. On the drivers side I can see the water lines on the bulkhead so I know it's running down from above I just haven't managed to locate it. Hopefully if it's dry this weekend I can get a good look and see where the water is coming from and see how easy/hard the fix is and if i need/can make up a drip tray to suit. My current fix of carpets out and sponge in footwell is pretty temporary!!! When you took me a run in your car I did get a drip on my leg I think through the bent not sure if it is related.
