Holy shit, why do i feel like grabbing my multimeter and checking this now. Thats a scary thought.
I had this problem on one of my old [strike]MKII's[/strike] 1977 Celica GT's. Ate the living shit out of the radiator, water pump and head before I tracked it down.
Nasty problem.

*screams* that doesn't sound fun 
yes definitely getting one of those multimeters today
i "did" have a leaking temp sensor but i kinda forgot to tighten it LOL

Galvanic corrosion is a mean thing. I flooded my computer once, running a water cooling system with a copper / aluminum waterblock. Ate completely through 10mm of aluminum in a couple months. One of the reasons why I find copper head gaskets to be such a scary thought with our aluminum head!
Luckily computer gear is pretty waterproof by now, or I'd have had to replace a crapload of expensive 'puter parts.

^ that definitely doesn't sound pretty
so how would i go about remedying this as i can't get an analog multimeter here so if i just do whatever the solution is, then i should be all good lol

Nick: There's something in the filtering of a Digi that stops it working.
(Haven't tried the new Fluke yet just my old generic Digi)
I ended up finding a analog MM at a local electronics shop.

Electrochemical reactions in the engine.. Galvanic corrosion..
Do I even dare ask how such a condition can occur in the cooling system?

Nick: Wow that's way high!!
From memory acceptable was 50mv
(I'll have to check that to be 100% sure it's been awhile)
<edit> Confirmed 50mv is the acceptable limit

Suze: Yes but now we need Nick to do the same measurement with an analog MM to compare. (Fluke's aren't your average Digi either)
so i'm wondering if i forgot a little bit of info which may be needed
My overflow is now on the right side of the car and it's on a 45deg angle (i think 45deg) so on one side of the bottle it's quite full, on the other it's barely even starting on the low side lol
here's a pic, you can't really see the angle too much here but you can see the lid is down quite far from the top of that panel

Here you can see the angle of the bracket, its supposed to be straight so you can get an idea of how much an angle it's on

I'd be willing to bet that IJ is right about digi mm's not being able to properly measure this, because that's a way high reading.
On the other hand, I would have thought that the digi mm would give a low read or no read at all, and not a "high false" reading.
Hmmmm...better get your hands on an analog meter.
