Yes, looking forward, in the airflow toward the front left cylinder,
which because it ran hotter that the other three had greater clearance
between piston and cylinder.

Correct, instead of a gauge, they had a lever so when the fuel got low
and the engines started to splutter you turned the leaver and this gave
you a reserve of about an Imperial gallon. You had to remember to turn
this lever back on filling, or you don't have a reserve and when out of
fuel you were stuck.

My Beetles didn't have any screw on filters, but when I swapped to a one
ton panel van (VW water cooled, same engine), that did have on it the
standard oil filter.

I think you mean "if you change the engine often enough." I am not sure
when VW added the oil filter but it was as big an advance as adding the
gas gauge and a real gas pedal.
