I recently modified the jacking points in the sill to let all the rainwater out that gets trapped in the sills. Sure enough there was a fair bit of water in there and I can see that water drains out from my newly modified jacking points after it has been raining. I was getting new rear tyres fitted today so the back of the car was jacked up high, both sides. All the time it was up there water was coming out of the rear jacking points. These are pretty much right at the back of the sills so I’m a bit mystified as to where the water was coming from. I would say over a litre came out of the passengers side. Any ideas?
