Ha ha. Well it's all done now. The white car was sorted and ready to stand in the garage and look pretty for weekends.
Annoyingly, if you look close you will see three dots near the front fender, two of them are oil stains. Had a good look, nothing at the front of the motor (well as much as you can see with the naked eye in that engine bay), had a look underneath the car and the back of the engine tray/cover has a thin coating of oil on it. Suspect the new gasket is leaking, well rather i hope.
Cleaned the leather, washed the roof, yada yada. Cussed at the mere thought of another bill
