Had a sudden loss of power coming home from friday, and could hear the turbo overspeeding... eventually tracked it down to the EGR valve being stuck open venting turbo pressure down the exhaust.

Have cleaned it all up and it works fine now, but I caught myself doing something very odd this morning.

I finished cleaning it and sat there thinking 'what can I do to it next?' - carried on busily and suddenly found an hour later that I'd cleaned every bit of plastic under the hood with the brake cleaner I'd been using. Made a hell of a difference to the look under the hood, but then I realised I'd done that without thinking - and it was pretty much unneccessary.

At what point does a hobby become an obsession I wonder, is it the point where you realise you're tinkering unneccessarily, or the point where you start getting bitched at by the wife?

Bah anyways, down to the business at hand:

I'll have to do the manifold shortly too:
