rain tray drainage

whilst hunting down my leak i decided to pour a huge bucket of water into my rain tray. probably filling it up about 2 inches deep and watched where it drained out.
  water did come inside down behind the heater box. is this normal? im guessing it went through the fan inlet and pored through?
  
  or should it be sealed up around that area?

 i think my drain holes may have been blocked so when im washing my car its been filling up and a bit getting in. does that sound logical.
 cheers

There are two drain holes at either end, common for these to get blocked up and rain back up through the heater opening. Make sure these are clear and you should have no more leaks.

4 drain holes? Mine leaks the same! Anyone got pics of the drain holes! I'm off to have a look! Could I have welded over the drain holes when welding the inner wings?

I think we need a section just for leaks!!!!!  

Sorry that should read - there are two drain holes, one at either end

Oh no! Is it normal for the heater box to leak, the 2 drain holes are clear! Sorry taking over!!  :mrgreen:

Drain holes:

Thatnks very much, they are clear on my car!

I think your problem is pouring a whole bucketful of water into your tray at once!
This is too much for the drain holes to deal with, even when clear, and some is bound to overtop the edge of the heater surround and pour down inside!
Test for leaks with a small flow of water from a hose, and keep it running while you carefully take back the carpets and look around the bulkhead. Mine had a rust hole by the bracket above the steering column, so water was trickling down there. Trouble is, you don't see it because of the carpets and find it fill the footwells! Even without using water, you can often trace the staining from water flowing in if you search carefully.
Good luck…

Shouldn't leak at all so something is amiss. Have you got the black plastic rain tray that sits over the heater in place?

Cheers

Yeah I have the try in place (brand new one cos it was missing!) Think  may have to check the windscreen for a leak
