Bentley's manual tells the reader that greater valve clearance should be set to HOT engine - .35mm and lesser valve clearance should be set to COLD engine - .30mm...

I find strangeness in these figures for the reason that everything expands in size with greater temperature - the camshaft becomes a bit wider, so do the rockers, and the eccentrics, and the valves, and everything else in nature...

The reasoning tells that therefore, HOT engine must exhibit LESSER valve clearance for the reason of supplanted space by the mentioned parts since they are greater in size. That is:

HOT - .30mm
COLD - .35mm
