I once helped a mechanic strip the head off his 4.2 Jaguar. He was convinced the head gasket had gone, but when we finally got the head off the gasket looked OK. Then he tested the thermostat in a pan of boiling water - and guess what !

He jumped up and down on the thermostat until it was wafer thin and then swore me to secrecy ..

There's a lot of talk these days about green transport. Well, I am ahead of the game, I already have green transport ... British racing green.
