(and please don't keep calling me Shirley. ;-) ). If the crankcase is below atmospheric due to the intake suction, and an air leak develops in the rocker cover due to a slipped gasket, won't air tend to flow through the crankcase to the air cleaner? If this moves the oil mist with it, won't that result in oil ending up in the air cleaner channels, and maybe some in the condensate tube? If so, some of the oil could leak out through the flap in the air cleaner or the tube valve. I'm just trying to work out why VW issued a bulletin to all VW garages worldwide with the warning that an ill-fitting RC gasket can cause oil loss from the engine in Types 1, 2 and 3 and the industrial engines. Another bulletin (Nov. 1972) says they are fitting ignition coils made by Lucas to some Type 1, 2/1600 and 3 vehicles except 3/1600 E (injection) on the production lines. I have an idea what Russ will suggest as a reason - probably something rude about our worthy long-standing UK manufacturer of auto-electrical items - but apart from not wanting to give him a reason to be rude :-) , why would they exclude the Type 2/1700 and the Type 3/1600E (injection) when they claim the coils are fully interchangeable? I'll laugh now so I can ignore the funny comments ..... ha-ha! Dave.
