The Disco has come up quite well with just a good was - 90% of the 'scratches' washed off. I'm going to leave the polishing for now - too much other stuff to do first.
Anyway, thought I'd go and bang some of that dust we were driving through, out of the air filter.
2 things I notice;
1) I've found the rest of the mud - the engine is covered. I guess the fan went in the muddy water. Must have been when I briefly parked so that 90boy could play with his tow rope. What's the best way to clean the engine? Can I just go at it with the hose pipe like I did the underneath???
2) I was a little worried by the amount of mud under the air filter. It was all before the filter, but it means quite a lot splashed in the air intake!!!! How much were those snorkels?
