Just a little update but one I think that makes a big difference.
Last two big bits of the engine bay were the cambelt cover and the cam cover.
Cambelt cover - all scratched and scuffed. No pics but this was sanded smooth, painted with plastic painted and new graphics applied:
Cam cover old vs new - the new one is actually different, it's missing the bracket to hold the airbox but the airbox is well held on without it.
All fitted - along with a new later type rubber gasket, stainless bolts and load spreaders. Makes the engine bay look much much smarter I think.
