80 Series water ingress

[SirNed]

Hi folks. BIL has got himself an 80 series but it is getting water in the Left hand sill. Pulling the drain plug out near the rear wheels when wagon is on slight slope and there is a good 2-3 litres of water that comes pouring out. So far have been unable to find where the water is getting in and was hoping someone has had the issue before and found the location. That is a lot of water over a day or so parked outside

Have looking in usual suspect areas like windscreen and firewall but cant see anything there so far.

For those who don't know I may have found the issue. From what I can gather water getting in is standard. Solution I found

The problem actually is the drains in the rocker panels and it applies
to all 80s. The drain slots are very small and clog easily.

There are three on the bottom of each sill under the doors, one near the
front, one at the middle and near the back.
They are right on the seam and can be difficult to find. When you have a
close look, you'll spot them. A fine stick or something will clear them
(actually, the thin end of a zip tie is good).

It is an idea to pull the rubber bungs and flush the rockers out every now
and then. They fill with dust and once water gets in, it makes mud.
