I thought I detected a tappety tappet so checked them. Used the method suggested on here about lifting one front wheel off the ground to turn the engine over - worked great Then got the Cif on the sunroof lining as the wife noticed my grubby hand prints all over it
- nice and clean now.
Suffering from a bad case of 'Mini Back' now after bending over under the bonnet, I'm sure a few beers will lubricate it back to health.
