- My model of MX-5 is: __2011 NC
- I’m based near: __Aberdeen
- I’m looking for technical help or recommendations on: __Water leaks - solved hopefully
Bought my car six months ago and managed to have a bit of fun between lockdowns.
Had a number of water leaks in the boot and in the cabin, not unusual given comments on the forum. Lots of help on Youtube on how to fix the issues.
1/ Leak into boot through an incomplete or cracked weld. Used automotive seem sealer on the inside of the boot to fix it. The weld is the short one inside the circle which starts under the boot seal and then come down the back of the car for 30mm. Bottom picture shows the underneath of the weld. Made a poor repair using silicone sealant but proper automotive seam sealer did the job.
2/ Someone had had the cable out of the boot lid at the car end, put it back in 90 degrees out and hadn’t sealed it. Siliconed in.
3/ Another cracked weld again sorted using seam sealer, took an age to find this. Right hand side of boot just in front of the hinge.
4/ Aerial dripping from underneath. The edge of the aerial at the bottom was missing part of it’s sealing lip. Siliconed underneath and screwed back on.
5/ Passenger footwell leaking in. Lifted seat and carpet to dry out underneath. Followed Youtube video on how to fix. The plastic grommet which takes the screw which holds the trim down in front of the windscreen had a felt gasket underneath which had long since disappeared. Bought new grommet complete with seal, put back in with uPol sealant. You can check for this leak by opening the glove box and looking forward and left towards the bottom of the windscreen, the rust from the leak is evident.

6/ High level brake light. The car is a folding hardtop. Again the problem seems to be the use of felt gaskets which have perished over time. On the photo, you can see the gaskets have disappeared around the bolts. Cleaned all the felt off and put silicone sealant around each of the bolts and where the felt seal was around the cable entry. Suspect that the right hand felt seal was the one which was letting the water in given the look of the roof panel before I cleaned it. Used Duck Tape Ultimate to replace the black tape shown on the bottom photo which holds the brake light cable in place. Not sure if there is something better. We’ll see how it holds.
Hope all that helps.
Hopefully that’s that, just driver’s side central locking actuator to change now. New one received yesterday…
