Hi Paul,
At the moment I've still got the coolant leak, and I don't have a valve yet. We unexpectedly had to buy a new fridge on the weekend, so cash is a little short right now, so I have to put the purchace of the timing light on hold for now. I'll probably get back on this project in a few weeks when I'm feeling a bit wealthier!
The good new is that the car is running very well on the points (when the cooliant stays in that is).
Cheers
Todd.
