The run to Chesterfield was 1.5 hr each way, mainly on the A1 but with some country roads at each end. So it gave me a good chance to do a proper test of all the recent changes I had made. And she passed with flying colours.
Major change was the cooling system. The indicator stayed pegged at the bottom of the Normal range for the whole journey. And more importantly she didn't lose any water over the whole journey.
The new bushes on the back shockers worked well. No more sign of the persistent squeak that had always been there. And the handling seemed much more precise and at 70mph she was absolutely rock solid. I'm not sure if that was the bushes or the raising of the rear ride height but it is definitely better.
The engine behaved impeccably, not hesitation, no popping, and even at 70mph, putting my foot down gave a very satisfactory push in the back. And the icing on the cake was she did 35 mpg, as against the previous 31 mpg. So the tea towel is working.
Very pleased all round.
