Thanks, Doug (I think... <g>). My transmission tunnel cover is in place, as are the carpets. The noise has to be pretty loud to be heard over all the other noises in a Spitfire at 70mph, and I'm still a trifle concerned. > >>Problem 2. >>Having left Crete in a temperature of around 87F yesterday afternoon, >>and collected my car at Gatwick Airport in a temperature of around 35F >>last night, I drove for a while with the windows shut.

Another correspondent mentioned that he had had a similar problem after his car had been left standing for a while, and that it went away after he had pumped enough petrol through the system to wet the various gaskets. His leak came from the fuel pump. Spookily, when I drove the car yesterday, the smell had gone, so maybe I've got away with it! I have saved your message in case it comes back, though...
