Looks like that didn't work, however ill get onto the works computer tomorrow lunchtime and see if its just an apple problem.

Regarding the breather system, I have a core plug on order that's hopefully the right size to just knock in then I shall drill/tap into the back on the block the new breather to go to the catch tank, also the rocker cover breather will go there as well.

I'm not too keen on the idea of putting the breather into the sump as in my mind breather is to release pressure from the engine from the little boost that leaks past the piston rings.
