Two long weekends, but it's all done and running like a dream.
I mainly just held spanners and got shouted at, but did manage to fix an electrical fault by changing the oil filter (don't ask)

We only had to change one part to get it running again, but as that part was the engine, it was a big job!
Huge thanks again, top bloke for giving up so much time to help out, having his tools abused and suffering endless p1ss taking from the Essex chapter!
