What might only look a minor coolant loss when the car isn't up to temperature may be amplified once the coolant system is pressurized up, therefore even a pin-hole will probably spray out enough coolant to cause you problems.
I think it was the last episode last week, was really good with the lotus, I always nearly well up at the end when they do the reveal. The episode where they fitted the servos were pretty good so they guy could drive it due to his health issues!
Easier if you have a ramp! Dropping the gearbox is fairly straight forward, and its not a complicated job to do once you have disconnected the slave cylinder, selector cabled, starter motor etc..
