Decided as I didnt really need the car this week I would have a bash at sprucing up the engine, mainly polishing the plenum.
After using the guides on here I whipped it off, nice easy job.
Next I attacked with a wire brush drill bit, Varying from large to shaped one for the more fiddly areas.
After removing all the main dirt/filth and down to clean metal I attacked it with Sandpaper - starting on 40 grit then 80, 240,400,800 and then finished with 1200. quick once over with Autosol Metal polish to finish.
I did I think about 40/50 mins a night for a few nights and then spent Sat morning finishing off, probs total time was about 4/5 hours but I am really pleased with the results.
