Does this engine look normal?

996T, underside looks kinda strange brown colour, is this normal for 15 year old car?

Looks pretty clean to me - Autoglym Engine Clean will remove most of the grime. New manifold bolts and lateral bars look rust free. Doesn't look like its had any off road excursions ;-)

Nothing to worry about. It's been treated with Waxoyle or similar. The air cooled cars were treated from the factory, with the introduction of the watercooled cars the practice stopped, so owners who wanted to preserve the underside of their cars (and specifically the engine cases) had a rust preventative applied at their own expense.

The engine pictured will have casings in excellent condition once the coating has been removed (by steam cleaning) but left untreated, a single winters motoring will see them covered in white powder (aluminium oxide) and looking distinctly secondhand.

Leave it on, or have it removed with steam cleaning and reapply for a cleaner look.
