Hi,
andyd - Yes No 3 was the problem on early VW engines - valve stretch was the problem, due to insufficient cooling. Valve adjustments were frequently needed and "the stretch" could be picked up via this
Around 1905 Porsche developed a four cylinder boxer air cooled aircraft engine for Austro-Daimler that was very similar to the VW of 1936-7.
In his Consultancy business from 1930 he worked on projects for many Auto Companies. He worked for Auto-Union and Daimler Benz and many others - always on Contract. His credibilty was always kept intact and I would have seious doubts about the Tatra story. Tatra were well known for their aircooled rear engined V8s! They are well known today for their heavy trucks
