Leaking runner 180.
Runner seemed fine no problems, so i gave it a bit of tlc by sticking the plastics on.
fixed up the side bit with green zip ties, matching!
straight away it sprung a leak. bloody senstive italian.
And now i have to take all the plastics off again. grr. Leak seems to be coming from the skull gasket, but it’s also over heating so it’s probably the oil/water pump belt after snapping, just like steves one. except i drove it further with no oil 
Got sparks with the starlet engine! no we don’t know what we wired to what or why and it probably won’t work again after it’s solderd up.
