Sorry Viper not got a clue as to modern Morgan construction.
If the hole in your pic is a drain hole, then I might use a hand held twist drill a little under the size of the hole, twisting it with my fingers or perhaps old style carpenters hand operated drill to try to clear the sealant, taking care not to damage the perspex.
Though if there is indeed a drainage system chances are that other than the hole the rest of the system may be gunged up...?
I guess it takes time to resolve teething issues with a hand built car.
My mid 80`s +8 seems to have been reasonably water proof, even in the worst of weather over the years, so it should be possible to sort it out..?
BTW many a Porsche convertible leaks water even to the extent of destroying under-seat located ECU`s... EXPENSIVE..!
Good luck.
Yes the other side has a hole which is only partially blocked with silicone. I’ve cleared them out so will see how it goes. Pretty soaked in there. I have a particular hatred for water ingress.
Yes we have a 964 here which pools up under the bonnet. Dangerous under there as you say.
Aero leaks like a sieve too, not sure I can stop that.
Etype leaks through the door panels despite going to great lengths with carefully constructed membrane etc.
I give up now
