Editing Z31/Underhoodcleanup php (section)

=== Process ===

The under hood of my 300ZX looked absolutely horrible. The original batch of owners didn't believe in flushing the cooling system; the system was full of rust and had developed a leak. Rust was sprayed all over the engine bay. Also, Nissan sprayed the under hood with a waxy film to protect the components. That had collected lots of dirt over the years and looked absolutely terrible. On top of that, valve cover leaks, morons pouring oil all over the passengers side, etc., had all contributed.

The first thing I did was to remove the under hood insulation. That stuff was in bad shape and there was no feasible way to clean it up. You can order a new piece,
