So heres how I got on...
long story short it goes again.
i got a local mechanic
to come and have a look and we turned it over with the injectors out and decided it was turning fine, had compression
, fuel and air.
So we put it all back together fired it up and it ran fine! Blew out a bit of blue smoke at the start but ran fine after that we took her for a burn out into the lake and back no worries.
When it ran away I knocked the air filter off and there is a foam insert that was half sucked into the intake manifold, what i didn't realise at the the time was that there was a supposed to be a plastic bit holding the foam bit in.
we guess that that plastic bit had got sucked in on the previous time i had run the engine and part of it maybe got stuck under a valve and when i topped up with oil it poured into a cylinder.
All good times. Onto the next problem, remounting the heat exchanger
