Thanks guys
Brummy, yep, no worries on the field. Maybe, just maybe, that'll change for next year!!
Paul, I used the following:
-Autoglym engine & machine cleaner, Tetroclean (this is really nasty stuff - wish i could find more of it!!) and some foaming degreaser from the same people who make WD40.
-Small nylon brush and a toothbrush
-Various rags, water sprayer
-High temp engine paint for the block and cam cover
-Meguiars vinyl care for the pipes.
Be warned, it takes a lot of time!! Once I'd started I felt I had to finish the job....
Andy, it was worse than in the picture on the last page!! It's basically 'all good' - just covered in 9 years of muck!!
