Whilst continually starting the car and trying to diagnose the issue over several days a horrid knocking noise started to appear from the bottom end. By this time I was really getting concerned so gave up on it myself and got it to a fairly local garage recommended to me by a member on here Rossi.
It came as a massive relief to hear that the knocking was not the bottom end but the crank pulley that was knackered. It was still an expensive part (About £160 worth with new bolt) and I had to wait around 3 weeks for it to be shipped over but it was definitely the lesser of two evils.
As you can see, the pulley was well and truly knackered with the outer part being able to shift from side to side, independently of the rubber damper insert. The knocking was the outer part of the pulley catching the crank case:

Not a job for the faint hearted I hear. Happy to have a go at most jobs myself but was glad to leave replacing this to a garage.
I also ordered this new arch liner cover to go over the new crank pulley:

This part was missing on my car so perhaps being more open to the elements resulted in a premature failure of the pulley?
