They always (all the ones I've taken apart) have a light brown glaze, but certainly not 'coked' in the sense you'd apply it to a cyl head. FWIW, I don't run synth, and I don't have any problems, even on my non-water cooled 16T. I've put over 60k miles on that car so far. I use a semi-synth Total oil which my motor factor keep in bulk. It works very well, and is about £8/5 litres. It also keeps my seals from leaking, which synths haven't done in the past. -- Grunff
