How do I find where the water is coming in?

[crazymatelot]

Guys, have just noticed that the recesses on either side inside the boot are actually soaking wet. I can't see where the water could be coming in, but suspect it may be dripping down from the hinge gearing. Does anybody have any experience or advice on how to cure this.

Pound to a penny it's the rubber boot seal not flush.

Checked that, the boot seal is pretty solid and unmoveable all the way around, to add to this, have now checked the rest of the car and the drivers footwell is also sodden. The car is normally garaged, but over the weekend I stayed with a friend and we had quite a heavy downpour overnight, I believe it was this that has caused the soaking.

Footwell will be clutch master cylinder - as in water ingress around it, not it's leaking clutch fluid into your footwell

A search on here will reveal most water ingress points. I would check the boot seal is actually making contact with the bootlid as well, otherwise you might be right with hinge points.

You could dust the area with some talcum powder which may reveal a water trail if it gets wet.

I have removed all carpets that will come out, I shall now dry the footwell out as much as possible. When it is dry enough I will try the talcum powder trick and put a hosepipe on the windscreen to see where the water is coming in. I don't believe it is coming from the door seal area, so suspect the front engine bulkhead is letting it in somewhere, such as has already been mentioned the clutch pedal area. hopefully this will pinpoint exactly where it is leaking.

Thanks for the help so far.

You could always try filling the cabin up with water and watch where the leaks come from...

It worked for me years ago. I used a hosepipe and sprayed a jet of water in all the likely places.

Hi crazymatelot - my Cerbera has been taking on water in the passenger footwell namely. Had lots of help from clever folk on here and found that checking the rubber seals where the different pipes come into the car, resulted in finding the leaks.

I removed most of the carpeting in the footwell and the leather panel too. I checked the seals, but it wasn't obvious, so with someone in the footwell, I poured water into the engine bay (carefully!) and waited until they shouted they were soaked! Thus identifying the leaking seals!

Hope that might help? Good luck!

Do what they did on Top Gear ..... fill it with water and see where it comes out.



Seriously, though, you could try putting paper / cardboard in the areas it's most likely coming in and see what gets wet.

Hi Dave

Regarding your boot leaks posible areas are:

1. Filler neck
2. Boot seal
3. Rear lights
4. Bootlid hinge securing bolts
5. Cerbera badge
6. Bootlight switch

Regarding water in drivers footwell the following are known causes:

1. The grommets which the throttle cable, water temperature capillary tube brake servo hose pass through
2. Clutch master cylinder cover
3. Pedal box securing bolts
4. Brake master cylinder reservoir
5. Bolts securing bonnet stay rod bracket
6. Oil pipe union
7. Scuttle panel securing riv-nut
8. Brake block mounted on toe board
9. Grommets in floor pan
10. Bonnet release shaft
11. Windscreen
12. Bolts securing bonnet lock bracket
13. Door seals
14. Steering column bearing
15. Indicator side repeater


Happy Hunting

Guys, so many possible entry points I just don't know where to start. Seriously though, a big thank you to one and all for your help on where to look, when I find where the water is coming in, I will let you know.
