Anyone know of a common a car in the uk I can get the throttle body to manifold o ring off of, went looking for vacumn leaks earlier and found a few.
IIRC this has the K3-VET engine, which means you want a Toyota Yaris 3SZ-VE (e.g. P1 Toyota Yaris) o-ring. Thats what I got for my Sirion Rally which is a K3-VE2 engine.
I have a spare one at home, I can measure the diameter when I get home later - its basically a generic o-ring of whatever diameter. Will update in an hour or two once I’m home. You can buy them from Toyota direct, but they’re not cheap!

OK, got back and measured it. The o-ring is 50mm inner diameter, and is 3.75mm diameter itself. The throttle body recess it lives in is 55mm diameter itself.
So I think if you can order a generic 50mm inner diameter x 3.75mm o-ring it ought to fit a treat.
If you really get stuck PM me, I have two in my pile of spares so could send one to you if crucial/can’t get one elsewhere.
This looks like just the ticket:

in 50mm ID x 3.53mm size? £0.41 (I’ll take the remaining £49.59 + VAT as a finders fee! 
)
They also do a slightly fatter 50mm ID x 3.80mm but thats a rather steep £2.12

If you looking for original parts number. here you go. This is from Toyota Duet/Dahatsu Storia K3-VE & K3-VE2 which should be the same size.
