Small update for over Christmas 
So, turns out engine was on its last legs pretty much which would of contributed to the running issues (Some i still have).
Whipped the head off and gave it to my Mums parter who works at Rolls Royce machining Trent engine parts. The head was warped slightly on one side it turns out, after he took it too work to work on. So I sourced another and he skimmed, tested and rebuilt it for me. All good
Replaced the head and gasket, Fired up..
Running on all 4 at last!
Or so I though anyway. Took it out for a short drive, didn't boot it for a while.. Kept it under 3-4k, Was sluggish and hesitant alot. I thought it may be down the the lambda, as its not in the manifold, but still plugged in, just tied up.
Turned around and headed home, thought I'd try putting my foot down.. Put my foot down, got up to speed pretty nicely, then Boom..Started misfiring when I got to 4k+ revs. And didn't stop misfiring.
Now, I no I lost servo assistance too around the same time, as I've had to somewhat bodge my servo hose on due to having a snapped lug, so its a thinner diametre at the Inlet end, So I think its that and it may have popped off.
I've sorted another top half inlet anyway, so I should be alright for that. Wont be here till later in the week/next week though So i'm stuck until then.
I also though it may be down to only having 3/4litres in the petrol tank, with it sloshing to the back maybe? or due to the fact I've still got a 1.1 fuel pump?
Anyway, enough of that shit.
I've bought some 283mm Calipers and Discs from a 307. 30quid
Sorted a set of Wishbones & struts from a vts as I'm going 4 stud now. I already have a beam, so thats good too
Wont be starting that until late january though and once my engines running decent.
